Okay.
WH11NE- Sunrise: thank you.
WH11NE- Sunrise: And so first, I'll give introduction production, physics, action, detection strategies. I'll go into detail about
WH11NE- Sunrise: the actual collaboration on its first step.
WH11NE- Sunrise: Hey? I'll go over the micro Mega detector, which is the one being developed. And if I have time I'll go over there. So background model the rest of this background on some specific background.
WH11NE- Sunrise: So I was already from the University of doing my thesis on production services,
WH11NE- Sunrise: I'm also a one of the developers of the rest of this framework, which is the the silver framework for the actual collaboration, and I am here for 3 months on. I just, related. But I'll try to spend the actual physics as well as I can.
WH11NE- Sunrise: And okay. So
WH11NE- Sunrise: a why search for actions so axioms are an elegant solution to this from city problem of the standard model. They are very weak, interacting and light and long lead particles. They are a dark matter, candidate
WH11NE- Sunrise: not another solution.
WH11NE- Sunrise: the experimental efforts to detect actions are growing significantly over time. They are still not there. That will be the win. But since we have not found the wing yet, the the search for actions are increasing, and
WH11NE- Sunrise: the relevant parameter space for action services is currently at the reach of current and future experiments which is exciting, and they are also hinted by some astrophysical data, such as the high energy gamma transpose transparency of the universe or the anomalous that are fully.
WH11NE- Sunrise: There are also some
WH11NE- Sunrise: yeah. Particles call action like reminder of the city problem.
WH11NE- Sunrise: And yeah, they used to be a Lagrangian and giving it symmetries, and
WH11NE- Sunrise: can accept a term an additional term of of the following, say, which is parametrized by this data hub parameter, which is on an right this term is doesn't usually appear we're getting to into. Why but
WH11NE- Sunrise: If it was in the Lagrangian this term
WH11NE- Sunrise: would break the it would break the Cp. Symmetry in the in the strong interrupts.
WH11NE- Sunrise: and breaking the Cp symmetry in the strong interaction has some consequences, the most, important one, or or easier to measure is the neutron electric type of phone, which currently is is thought to be 0 or it's measured to be 0. But if Cp symmetry is not construct in the strong interaction, it will not be 0.
WH11NE- Sunrise: So there are, efforts to measure the internally type of moment graph.
WH11NE- Sunrise: And, we have gone to very, very low limits for its value. And we find it basically to be to be seen right? Which this gives us a very stringent restricted after phone for the parameter, of 10 to the minus 10. And remember that this parameter is supposed to be an
WH11NE- Sunrise: so basically, this tells us that the Cp violation industry has not been observed.
WH11NE- Sunrise: That's good. Yeah, maybe I will. Jump between slides. But oh, okay.
WH11NE- Sunrise: yeah, I think I can't.
WH11NE- Sunrise: Yeah, right? Yeah.
WH11NE- Sunrise: yeah, okay. Okay, thank you. Yeah. So basically this so this, this fine tuning problem is what's called the right. So this parameter could just be as small as if it's
WH11NE- Sunrise: in principle it would not break anything right. But from experience, we know that this usual teams towards new offices that maybe I may explain this better. So there is some solutions to the to the strong city problem.
WH11NE- Sunrise: for example, if we introduce some of the spark. The the problem solves itself.
WH11NE- Sunrise: but the most
WH11NE- Sunrise: the preferred solution by the communities that say which is the actual.
WH11NE- Sunrise: The this action particle has some properties. It is a very live with a mass range between 10 microelect, dependent on the model.
WH11NE- Sunrise: It has very weak interaction support with the standard model.
WH11NE- Sunrise: in particular. The most important introduction is the coupling autumns via what's called a primark effect, and we can see here are the 3 Monday
WH11NE- Sunrise: this interaction
WH11NE- Sunrise: tells us that the action can be converted into photos, and vice versa under strong electromagnetic fields. And this is the base the the principle behind actual text the conversion.
WH11NE- Sunrise: and so my previous actions would contribute to the hot or matter in the universe, just like a neutrinos. But more more interestingly.
WH11NE- Sunrise: actions produced by other means just the mechanism in the early universe could explain the call that are mandated in the universe. So they are a dark matter
WH11NE- Sunrise: on top of this what I described as a solution of the problem I call action. But there are some other particles called action, like particles which serve similar properties, but do not come from the same,
WH11NE- Sunrise: Do not come from the sometimes it's confusing, so we may call Qc. The action this that I just described an action to the general particle that serve this property or just call action. Take, you see the action and action like particle.
WH11NE- Sunrise: So when we say, action searches, and where you are talking about action like particle searches in general. So this is the exclusion plot for action on searches. It's basically, I would say, the most important
WH11NE- Sunrise: block in action services where we
WH11NE- Sunrise: and so on. The on the X-axis is the mass of the action, and on the way, axis is the action spot on the another exclusion product is interesting is the action to electron coupling. But for example, this actions electron coupling is limited by aspect of this limits, not by experiment. So this is the important one. When we are talking about experimental.
WH11NE- Sunrise: Yeah, excellent. So it has a few listing regions.
WH11NE- Sunrise: on the right we have the physical or cosmological limits for the action mass on accounting.
WH11NE- Sunrise: then on the top left. We have. What's labeled laboratory, which basically corresponds to a lifetime through wall experiments which are over in detail. Then we have this blue region which corresponds to the Heliosco experiments.
WH11NE- Sunrise: The
WH11NE- Sunrise: doing vertical lines correspond to to a Hello scope experiment. And then we have this yellow diagonal band which corresponds to the region of the parameter space where the Qc. The action would leave
WH11NE- Sunrise: right because, there are some constraints for the
WH11NE- Sunrise: but everything outside of this would respond to
WH11NE- Sunrise: do actually like particles. But they are also interesting. Right? Searches usually focus on on this blue and yellow dialog.
WH11NE- Sunrise: So okay, so first, I'll talk about how scope experiments.
WH11NE- Sunrise: So these experiments are rely on the fact that
WH11NE- Sunrise: the dark matter halo
WH11NE- Sunrise: is composed of of actions right?
WH11NE- Sunrise: They are resonant cavities that are tuned to a specific frequency
WH11NE- Sunrise: photos and signal.
WH11NE- Sunrise: and they are obviously very model, dependent right? They would not. Even if actions existed, they would not detect them if they were not. The main component, like the dark matter hit. But this kind of experiments are very
WH11NE- Sunrise: a particular
WH11NE- Sunrise: and properties in the indexation grab us. They
WH11NE- Sunrise: they only explored a very narrow, a mass range, but they can reach very low, values of the company, and you can see here, the values, obviously this, the mass values that this is going to explore are those that are compatible
WH11NE- Sunrise: with the dark matter hypothesis right now.
WH11NE- Sunrise: and
WH11NE- Sunrise: maybe an action of higher mass would not, be able to explain that matter situations.
WH11NE- Sunrise: So such, then, so in principle, assume a particular particular dark matter. Density.
WH11NE- Sunrise: such? Or yeah, II. To be honest, I'm not really sure about the the physics of
WH11NE- Sunrise: II wouldn't be able to. But yeah, I'm not very familiar with how scope besides what I just described. So, yeah, can you expand more about the middle class, like the frequency of power.
WH11NE- Sunrise: So I guess the frequency is
WH11NE- Sunrise: So so this is like a radio frequency
WH11NE- Sunrise: restaurant company, right? and you expect the
WH11NE- Sunrise: just picked out already. Seen them.
WH11NE- Sunrise: And so basically you you, the action would.
WH11NE- Sunrise: So so your cavity would take some energy from the action field from the A from the action field right? And and get
WH11NE- Sunrise: get some forward out of the time. I'm sure I explained the your question right? So you will see some.
WH11NE- Sunrise: You would see a signal. So you put this experiment in a very control environment where there is no background. So I'm not very familiar with the background, this type of experience. Because II will get into our experiments. They are.
WH11NE- Sunrise: And so so the photos are, we typically detect our X ray photons right? But these particular experiments they detect right if you want to see photon right? So I'm really familiar with the
WH11NE- Sunrise: with how the specific experience are not. But basically, it's just to do to the text on signal where it's not supposed to exist. Right? Okay? So through all experiments.
WH11NE- Sunrise: and are probably the most basic experiments in the sense that they are the less small dependent. They just rely on the physical properties of the actions. How to start converting to photos on vice versa
WH11NE- Sunrise: on the working principle is. it's pretty simple. So you basically have some source of photos on one end you would convert these photons into actions under our strong magnetic field.
WH11NE- Sunrise: This conversation, by the way, preserves the energy, I'm on the accent, right? So the photon. the actions of confession that is looking practical to have the same momentum on energy.
And so you can't do this right?
WH11NE- Sunrise: And so typically it's action. 2 photon process. But one of the photons is arbitrary photon. Right?
WH11NE- Sunrise: Yeah. Okay. so you produce some photos
WH11NE- Sunrise: through some work, basically
WH11NE- Sunrise: in such a way, that apple don't kind of go through the world and then try to convert it back into an action on the other side. Right? So it's pretty simple concept
WH11NE- Sunrise: and
WH11NE- Sunrise: less one independent. But it doesn't produce very strongly limits, right? Because you need to convert it twice. So this limitation.
WH11NE- Sunrise: the Helisco. Experiments are the ones that our group focuses on, and are those that try to detect actions to produce in the sun? Right? Because the the sun, obviously has a very strong electromagnetic field inside, and this primark of conversion would take place in the sun. Right?
WH11NE- Sunrise: It doesn't have anything to do with our matter. Right actions may not necessarily compose with our matter, but they would still be produced in the sun.
WH11NE- Sunrise: and
WH11NE- Sunrise: it has a more competitive performance than the lifetime through all experience actually is, is the most competitive in this region
WH11NE- Sunrise: of the environment space.
WH11NE- Sunrise: Why would you do it in a lab.
WH11NE- Sunrise: That's a good question.
WH11NE- Sunrise: Let's people do.
WH11NE- Sunrise: Yeah, I mean, I guess it's because this is the purest way you can do it by the most model independent way. Here you have some
WH11NE- Sunrise: is a you need to have, like a good solar model, right? That they you need to know the precisely the say, the spectrum of the lots of solar action. Samsung. Right? So
WH11NE- Sunrise: it's better right in in. It's it's better. But it's more modern independence. So I guess it's always good to cover the department space in a different way. Right?
WH11NE- Sunrise: Okay, yeah. Yeah. The reason I can go to lower limits is just because there's more photos.
WH11NE- Sunrise: that's a huge magnetic field and a very huge
WH11NE- Sunrise: once right? You only need to convert the actions into photos. In your experience, you need to convert the photos to actions, and then the actions. Right? So it's like a double conversation. No, but here it's also twice right. The first time happens in the sun.
WH11NE- Sunrise: Oh.
WH11NE- Sunrise: company, to be honest.
WH11NE- Sunrise: I've never sight I sent to all experiment in detail. Right they are. I don't think they're very popular. Let's say that people focus more on the Helesco experiments.
WH11NE- Sunrise: I'm not really sure if we like. If people put the same resources up are being thrown to telescope in in the laboratory experience what we would get right? I think there's a similar exam.
WH11NE- Sunrise: I didn't get it. No, it's not a question. It's like
WH11NE- Sunrise: that. We probably have. Yeah, yeah, yeah.
WH11NE- Sunrise: why don't we? We make our yeah make high cube cavities? It seems like you would use them to do this.
WH11NE- Sunrise: Yeah, actually, for example, this, this kind of experiments are usually so in our experience with the past experiment that I will talk later. We have this restaurant cabin inside the Aesthe, because there is room for it, basically. But there is no reason
WH11NE- Sunrise: it doesn't need to track this on or anything right? So
WH11NE- Sunrise: would be done. So so basically, the hell scope, wise sort of Kevin, the next 5
WH11NE- Sunrise: next next slide next slide. So basically, the help school wise on the right side of the is basically the right side of the direct, basically the right side of the because you're measuring things from the size of your
WH11NE- Sunrise: the yeah. The thing is the
WH11NE- Sunrise: okay. I'm not really familiar with the energies of the on on the left, right for the actions, but they would be
WH11NE- Sunrise: on on the lower end. This is like zoom visible, right? Right?
WH11NE- Sunrise: Oh, interesting. I didn't know.
WH11NE- Sunrise: That's that's quite interesting. Thank you, Andrew. And Jim.
WH11NE- Sunrise: Interesting.
WH11NE- Sunrise: Okay? I'll continue.
WH11NE- Sunrise: Sorry. Close to 10.
WH11NE- Sunrise: That's okay. I'm monitoring chat. Okay? Where? West side?
WH11NE- Sunrise: Yeah. Okay, yeah. So so. And all stars for the Saxons. Right?
WH11NE- Sunrise: It's actually one of the explanations, one of the theories to explain that I want to start pulling, which is an open problem that basically says that stars, are pulling faster than what we would expect right? So, pulling through actions.
WH11NE- Sunrise: it's an additional mode for pulling, so it would explain why they are being pulled
WH11NE- Sunrise: faster than that, right? And there are some models to explain what to describe the spectrum of actions.
WH11NE- Sunrise: I won't go into details. But basically it has a difference between the models and the roughly 10 kv, right? So they have energy experts. Right? So when we compare the the action. 12 of them we need to detect on X, right?
WH11NE- Sunrise: Okay? So the key components of a helicopter. Basically, you need to have a more platform that is able to point the telescope to our assigned. You need to have a very strong magnetic field
WH11NE- Sunrise: that is, carbon nuclear to the optical axis.
WH11NE- Sunrise: And then you need to have some X-ray optics that would focus the X-ray bottoms into a into a right and obviously is detector would be would need to have the lowest background possible, because we are like in something very painful. So typically this is a figure of made for telescopes, which is separate out of 3 things, the market.
WH11NE- Sunrise: the the texture on on the optics on the tracking time. Right
WH11NE- Sunrise: here is the cost experiment, which is every successful
WH11NE- Sunrise: that has been running from 2,002 until recently to 2,022
WH11NE- Sunrise: it was hosted at absurd near Alex TV.
WH11NE- Sunrise: It just length of 9 25 meters.
WH11NE- Sunrise: And this blue thing, big big blue thing in the middle is the market.
WH11NE- Sunrise: And it hosted a different detector technologies. Right? So
WH11NE- Sunrise: here you you can see the an experiment. Right? So here is the mobile platform that displays the
WH11NE- Sunrise: so we'll rotate the experiment, and then it has like a thread that elevate the desktop. But, as you can see from this image.
WH11NE- Sunrise: then it is very limited in movement. Right? This is a very basic experiment. I mean this using, you know, some solids magnets right on becoming some magnets. So it it's not really signed from the grown up report. We are making the best of what was available at the time. Right? So
WH11NE- Sunrise: by the way, here in the gas. We have 2 2 sites based on set detectors and the sound rest detectors because they
WH11NE- Sunrise: only only one side can point out the sun other than right. It's not like a full Tesco where you can fully rotate it.
WH11NE- Sunrise: and it had, like a tracking time of probably one and a half hours each day for each side. Right? So after 24 h. And this is very, very low, tracking time right? And remember you.
WH11NE- Sunrise: you just need to point out the sun right? It doesn't need to. Life doesn't need to reach experiment. You can point through the earth or whatnot.
WH11NE- Sunrise: and the results from the cast experiment our link here. It's an upper limit for the actual copy of point 6 6 10 to the time 10
WH11NE- Sunrise: times. It's 10 to understand Tvs.
WH11NE- Sunrise: And so my clients. okay, so as a continuation to the test experiment we have Ixo. which is a platform for action detectors specifically designed for this right with a magnet specifically constructed for this.
WH11NE- Sunrise: a trucking system. And actually, optics.
WH11NE- Sunrise: So this would be the appropriate concept, for I actually much bigger than cast. You will have at the right environment, 20 meters long.
WH11NE- Sunrise: with 5.4, which is lower than a cast. But it's the important thing is that my volume, which would be much higher, you will have 8 more. So 60 cm. You would have a dedicated X ray optics tracking system, which would allow 50% time.
WH11NE- Sunrise: and then it would be able to accommodate different detective technologies in particular, micromanage, which is the one that my group focuses on, which is the baseline detective technology forecast. But it would be like a platform where different research groups can put their expect right. We just provide the tracking and the magnetic field on experiment can put it's detector
WH11NE- Sunrise: at the other end of the of the world. So before building a I actually.
WH11NE- Sunrise: and the first step is constructing baby actual, which is a kind of like a finder, or a proof of concept, but it is significant experiment in itself, because it would improve the the results of past right. So this experiment is currently a under construction in the C German
WH11NE- Sunrise: it was originally planned for 2,024, but there was some
WH11NE- Sunrise: delays with the with the magnet that we are trying to
WH11NE- Sunrise: to solve at the time.
WH11NE- Sunrise: But hopefully soon it will be. it will be ready.
WH11NE- Sunrise: So this experiment has 10 meters long.
WH11NE- Sunrise: And okay. So here are the prospects for the yes, you can see, we would reach lower values of the company.
WH11NE- Sunrise: even for maybe actually significant and working. And most importantly, we would explore this region of the Qcp. Right? Which is the the most interesting thing.
Okay?
WH11NE- Sunrise: And
WH11NE- Sunrise: you, you need to improve this significantly to to improve the the company. Right, for example, in the case of the full X experiment, the synapse ratio ratio would be improved by 4 order of magnitude, but this would only translate into one a ordering the actions.
WH11NE- Sunrise: Okay, so
WH11NE- Sunrise: are there some
WH11NE- Sunrise: dash lines also, for the haloscopes being showed there. Cause I see some like like other
WH11NE- Sunrise: in the paper.
WH11NE- Sunrise: yeah, they would be that their high school experience, right? So probably at at this time this look is not the most they have already.
WH11NE- Sunrise: uncovers some personal of these reasons. Right?
WH11NE- Sunrise: So, so that was like a platform like multiple planned experiments. Exactly. Yeah, exactly. Yeah. So this would correspond to. There you go. Oh, nice.
WH11NE- Sunrise: Yeah, I don't. I have a lot, a very large amount. Think? So this are some data about the magnet. I'll just skip it the X-ray optics, we are gonna be using dedicated X-ray optics which come from newstart telescopes built by NASA
WH11NE- Sunrise: on in.
WH11NE- Sunrise: So they are. Currently.
WH11NE- Sunrise: we currently have access to one, spare a sorry optics that was not into space.
WH11NE- Sunrise: The okay. So going to the detectors.
WH11NE- Sunrise: which is basically what we focus on on my university right, the development of the of the sector.
WH11NE- Sunrise: And you need to have a a internal background. Right? You are detecting something that
WH11NE- Sunrise: it's extremely extremely low rate
WH11NE- Sunrise: the background units that we use are these ones? Right? We we call this background units, which is coms per a Kv person images per per second. and in the region of interest that we
WH11NE- Sunrise: we are discussing, which is between one and 10 kvis, something like in disorder
WH11NE- Sunrise: the detectors have been using cast from time, and they are influen our reliable technology.
WH11NE- Sunrise: But we also support a
WH11NE- Sunrise: other technologies. And one of the advantages of this Micromegas technologies that it is intensively ready view, right? So that the material is used for the construction are not radioactive for us as the lowest amount of activity, and that you can't get
WH11NE- Sunrise: because we can't control the full
WH11NE- Sunrise: manufacturing process of the
WH11NE- Sunrise: of the detector, and they are pixelated detectors.
WH11NE- Sunrise: So we can use a discrimination and strategies right with the should be data, or through your data.
WH11NE- Sunrise: And to remove a bugger events, right
WH11NE- Sunrise: is, remember that we are trying to detect low energy. X-ray follow ups and interaction. I mean, the detector would be
WH11NE- Sunrise: and point like, right? Because it's
WH11NE- Sunrise: which would interact in a yeah like process, and would just be a point like the position. So having app isolated
WH11NE- Sunrise: detective would enable us to reject most of the background very easily.
WH11NE- Sunrise: And then we have some silliness strategies for the director
WH11NE- Sunrise: the the directories the first layer is, really pure cover electrophone cover. Then we have some. Let's see, to protect from a cosmic background
WH11NE- Sunrise: which is 20 cm thick with an inner layer of.
WH11NE- Sunrise: And then we have some active system. Right? So one particular interesting thing about the
WH11NE- Sunrise: at least a technical right is.
WH11NE- Sunrise: it is internal background. Detector parties hosted in above ground. Right? So typically, these types of detectors are in underground laboratories. But because, the experiment. That platform is so be it cannot be sleep in an underground. So we need to
WH11NE- Sunrise: to reduce the the background as as much as possible and
WH11NE- Sunrise: face some backgrounds that maybe are not relevant in underground experiments. Right? For example, cosmic new terms
WH11NE- Sunrise: are typically not a relevant because they do not reach underground. But here are our our problem because of their interactions.
WH11NE- Sunrise: Okay, so and the Microsoft victim, yeah.
WH11NE- Sunrise: do you lose any? If you went underground. Do you lose any tax? It's just basically that
WH11NE- Sunrise: it's to be to fit on the ground. There are some places, I think, in China that is on underground that would fit the experiment. But it's not been
WH11NE- Sunrise: so. We we need to do it on this. How big is it? Just 20 meters? Here we have a scale.
WH11NE- Sunrise: some person right? So 20 meters of of length of the of the magnet. But then you have you? Do you have more more more stuff, right? So the optics
WH11NE- Sunrise: so so the mindset would be
WH11NE- Sunrise: here right? I don't know. I don't know.
WH11NE- Sunrise: Probably 40 50 meters I don't know. All. The probably have like much bigger.
WH11NE- Sunrise: like.
WH11NE- Sunrise: I'm not sure of how much buffer.
WH11NE- Sunrise: I mean, if we would, we would do it on the ground right, there would be a challenge to target a sound right? Because this is extremely challenging it. It may seem easy at first, but
WH11NE- Sunrise: tracking the sound without seeing you need a very high precision is is not easy, right, for example, in experiment.
WH11NE- Sunrise: and that is like a window that aligns with. So there is some plugin system is very complex, and once a year some comes through our window and you can check that. Everything is working correct, right.
WH11NE- Sunrise: But if you were underground, may you will need to improve it.
WH11NE- Sunrise: You need to do it another way, right? Because you cannot see.
WH11NE- Sunrise: Okay. So
WH11NE- Sunrise: it's pointing out of the sun. Yeah, you need to. But so that cast experiment was pointing, just
WH11NE- Sunrise: based on measurement in one time a year. Calibration, yes, and the rest is like, you know where the sun goes. So. But if it worked, I mean it was running for 20 years on every year.
WH11NE- Sunrise: I was right? Yeah.
WH11NE- Sunrise: yeah. So micro, masters are guys with Dpcs, right? Yeah, you can see the working of A of a Dpc, you have some region, and you have some amplification right?
WH11NE- Sunrise: And so here, on the left itself. It's this
WH11NE- Sunrise: square thing, right? It's 6 by 6 centimeters. it has a pretty good energy and energy resolution and very good special resolution.
WH11NE- Sunrise: And most interestingly, it's it's right here.
WH11NE- Sunrise: So in in my university, we are. We have.
WH11NE- Sunrise: Yeah, different sets of these detectives. Right? How did you ensure that it is ready up here? So, okay, yeah. So
WH11NE- Sunrise: because I've known a number of very sensitive dark matter, experiments that have got had to go to really extreme links to make something radio. So we have the 20 year experience in past.
WH11NE- Sunrise: where? I I'll taste like a section in the presentation for. But basically, we, we are experts in right? I'll go over later. Yeah, yeah, there are people in our group that basically
WH11NE- Sunrise: so the technical they produce and we are characterizing them right? We are doing test
WH11NE- Sunrise: I can only top left
WH11NE- Sunrise: experiment with that assistance later. And then we are also doing test of the underground laboratory and come from right in in Spain and
WH11NE- Sunrise: in the earliest right. We have another laboratory where we we have been collaborating for a long time.
WH11NE- Sunrise: It's not very, very deep, right? It's only 700 meter water equivalent, I think. But for this is good enough, right? So we can characterize the the background of the detector.
WH11NE- Sunrise: See what background phones from cosmics and what doesn't alright?
WH11NE- Sunrise: So in in a discussions detector, we use ours on isobutane mixtures typically, and we are also assigned the possibility of using ceno. Right? So Argon has been working the best for us. But they just like a slight problem that there are some
WH11NE- Sunrise: argon. 39 is very active. Basically. So it would be
WH11NE- Sunrise: an intensive social background. That's not really a problem, because it's very low on once. But if using Ceno, for example, will run with this background.
WH11NE- Sunrise: So here you can see the window.
WH11NE- Sunrise: That's right window, right? So they express phone from the from the magnet to the background, they there needs to be some interface between the gas and the
WH11NE- Sunrise: and the vacuum. Is this in Milar window, which is, I think, 200 micron, thick very transparent to X-rays. And this is
WH11NE- Sunrise: 4, 5 calibration both right where we can see the we would put that calibration source, and we can see the outline of the window in the in the micromics.
WH11NE- Sunrise: And yeah. okay, and here you can see a sample spectrum of of this detector. Right? So and no, we like get an order of mind where we're talking about. Right? So, for example, when we say alternative resolution.
WH11NE- Sunrise: we are talking about this, right? So this would be a 5.9, a TV photon from I don't. 55 source
WH11NE- Sunrise: in right maximum here.
WH11NE- Sunrise: if compared to Germany detectors, for example, you say, say say that this, but it it works fine enough, right?
WH11NE- Sunrise: We've care more about the It
WH11NE- Sunrise: precision. And next right, for example, in order to do this parentheses. Okay? So going back to radio purity.
WH11NE- Sunrise: So our research group has a very long history of the developing right here, detective and doing measurements.
WH11NE- Sunrise: And the underground authority, for example, has a service for measuring
WH11NE- Sunrise: and
WH11NE- Sunrise: a service with a German detectors for measuring very low the backgrounds right?
WH11NE- Sunrise: And we have built over the years a very detailed right beauty database right of different components. And down to the, for example, when we are designing the electronics week.
WH11NE- Sunrise: Take a sample from the manufacturer of every literally, every every piece of the board right, the capacitors, the
WH11NE- Sunrise: the resistor, the tips, and we measure the background of of these components right? Take loose use every everything you can think of
WH11NE- Sunrise: right. And we have a long history of
WH11NE- Sunrise: and working with the people that make this detectors. We are aware of the processes they use to make the directors right down to the materials that they are using where they source the copper with a assets. For example, they use in the processing right? Not not just the material. So that's products that they use. Sometimes we have issues right? Because they were using zoom. That was more
WH11NE- Sunrise: for this this process. Right? So this one, the relativity of the detector, is is pretty under contract. and
WH11NE- Sunrise: and we also have extensive experience of simulation of known right. For example, as I told you, they are on 39 presence in, or a led to 10 intellect.
WH11NE- Sunrise: okay, so I'll go over the background model.
WH11NE- Sunrise: what is that pitch for like? Is that the lab where you do the test. So yeah, the the laboratory is actually situated in.
WH11NE- Sunrise: So the entrance is
WH11NE- Sunrise: like in the middle of the tunnel between Spain and France. So when you go by car from Spain to France. It is like a huge tunnel that you give the Pyrenees, and you go.
WH11NE- Sunrise: You enter the laboratory through there right? And this is how you exit. The laboratory, which is a tunnel that is not under us is our old, but it's now it's only been used for the laboratory. Right? But it it's okay. So the background model for experiment. And there are some contributions. For example, you have the
WH11NE- Sunrise: a contamination alreadyogenic activation of the different materials in the detector, such as the vessel decision, the attorneys, and so on.
WH11NE- Sunrise: And then you have the environmental background
WH11NE- Sunrise: coming from a gammas,
WH11NE- Sunrise: From the case around the around the experiment. And then you have some very specific backgrounds, such as around 39.
WH11NE- Sunrise: If you are using outbound mixture, which is the most likely scenario.
WH11NE- Sunrise: and then you have a background due to custom. Grace is where I work most, on, this cosmic rate background can be basically broken down into 3 components, the meals, the
WH11NE- Sunrise: energy gammas? Right? So these particles are produced by cosmic racing. The atmosphere. And this would be like the way to deal with each of these backgrounds. Right? So, for example, for a contamination environment, you just increase reliability.
WH11NE- Sunrise: And you can seal from environmental calendars or environmental interrupts.
WH11NE- Sunrise: You can, for example, use 39 or just use a different mixture. We are not using our Ipr argon right now, because it's extremely expensive and they level off background. That argon 39 introduces is not.
WH11NE- Sunrise: That's significant at this time, but, for example, if you improve everything else, and there would be solutions for the for the argon so for the cosmic race the biggest phones, right? But they are very easy to steal from using vetoes.
WH11NE- Sunrise: A 100 cameras, according to our simulations.
WH11NE- Sunrise: are not significant social background. It's basically impossible to
WH11NE- Sunrise: to shield from them, right? But
WH11NE- Sunrise: their contribution is not that significant? And currently, we're focusing more on the on the right.
WH11NE- Sunrise: is, neutrons are particularly difficult to to seal from right, because the scene how they would produce in the is basically indistinguishable from the
WH11NE- Sunrise: from the axion for them. Right? So the photon from action. Compression is a low energy X-ray that would just produce a point like interaction via photographic effect.
WH11NE- Sunrise: I'm a neutron
WH11NE- Sunrise: can produce up point like interaction. Also in the detector. So basically, from the readout point of view, it's impossible to distinguish some of these events. So we thought about the how to solve this. And
WH11NE- Sunrise: we are developing
WH11NE- Sunrise: unusual time system that I'll I'll discuss later.
WH11NE- Sunrise: Okay. so
WH11NE- Sunrise: and what? So rest of physics is the software framework that we are using in this in the actual operation, right? It has
WH11NE- Sunrise: a so basically, it appeared as as a way to unify how we did
WH11NE- Sunrise: how everybody in our in our group did the analysis right? At some point we came together and said, Okay, let's put it together as a single. So we're framework. That's happening
WH11NE- Sunrise: 2,014, right? And it's being used,
WH11NE- Sunrise: By users from different institutions.
WH11NE- Sunrise: So it is a
WH11NE- Sunrise: so preference originally, Jared? Towards Tpc. Experiments. But it is fairly generic, right? It can be adapted to different experiments if there is a willingness to do it.
WH11NE- Sunrise: I forgot to say, it's root based, but heavily based on route which has its pros and contract
WH11NE- Sunrise: it has a modular structure, so it can do. Basically, there are packets to many things. Right? So, for example, multi cover simulation using jump for a or different analysis right away from analysis or analysis of the
WH11NE- Sunrise: Hope Monte Carlo.
WH11NE- Sunrise: So basically, the the idea of the server framework is to have a unified event format for this data. Right?
WH11NE- Sunrise: So it's it's a. The event is like the best the most important thing in in this over framework. And you go from one event type to another event type through zoom processes. I know. In the meantime you feel some some routine where you come in later to your analysis.
WH11NE- Sunrise: In our experience, risk has been useful. Especially they when being with other guys. Right? So for
WH11NE- Sunrise: and
WH11NE- Sunrise: education projects right for students is not easier to than using our arrest for physics framework, and, for example, using pure or pure route, because the students usually don't have enough time to
WH11NE- Sunrise: and to learn these these tools.
WH11NE- Sunrise: So here are some links for the, for a paper, for rest, for example.
WH11NE- Sunrise: and details on. We also have this call experiment, which is a direct
WH11NE- Sunrise: and it's the official sober framework of the actual colleagues. And
WH11NE- Sunrise: so right? So right
WH11NE- Sunrise: from route, right? It probably doesn't need to inherit from the object at this point, but that's on our topic.
WH11NE- Sunrise: It can be serializing in an event. 3.
WH11NE- Sunrise: And the different rest processes take you from one event to to another right? So in this case, for example, you would do a jump for simulation you would produce and then you would apply some process that would take 70 to for example, what you have wave forms. And in the meantime you can also do other processes that would just produce some of the roles that would be safe.
WH11NE- Sunrise: I'm 12, 3
WH11NE- Sunrise: in a rest file. You basically have a run restaurant
WH11NE- Sunrise: which is stores all the information for the file. So there's one run for the file, and it's a convenient way to access updates, inside a file. And we have this mental data class which basically allows to return
WH11NE- Sunrise: great configuration files for our analysis. So rest is a very dependent on configuration files. They would start based on Xml, I,
WH11NE- Sunrise: we probably want to do channel at some point.
WH11NE- Sunrise: yeah. So basically, we have the inventory where we have the full limit data. And the analysis, too, where we have a simple treat that can't be analyzed
WH11NE- Sunrise: data. We have the rest.
WH11NE- Sunrise: We have a bunch of metadata here, right? So every process that we supply this you rights
WH11NE- Sunrise: unmute on the file with what it did. So we have some very good traceability.
WH11NE- Sunrise: We can go back and see what how the file was analyzed.
WH11NE- Sunrise: The okay. So, for example, here it's other house sites, Where we go from?
WH11NE- Sunrise: from to the event. Right?
WH11NE- Sunrise: After analyzing the the waveforms.
WH11NE- Sunrise: And we apply
WH11NE- Sunrise: and sector electron process, right? So so basically sorry, this event would be produced from a simulation.
WH11NE- Sunrise: we simulate the techno response. And then we can, for example, for example, simulate the electron diffusion and the base. In order to have the
WH11NE- Sunrise: this result right? Or we can apply this this processing, for the wave forms right? So this would be the output of you obviously have some deltas. Then you have, correctly constructed your detector response.
WH11NE- Sunrise: And you can
WH11NE- Sunrise: we get the
WH11NE- Sunrise: yep, okay.
WH11NE- Sunrise: So that's finalized. I'll go some of my work, in the.
WH11NE- Sunrise: in the cosmic mutual background for experiment?
WH11NE- Sunrise: Remember that the this experiment, this is about ground, right? So very special backgrounds are important here which are not important in our experiments.
WH11NE- Sunrise: and
WH11NE- Sunrise: the are right because they have not been tied by many other experiments. Comparison to to, for example, that even reach is not very effective.
WH11NE- Sunrise: And we thought that it was thought you was. So. This is the time system that we developed. It's under development right now, right? It's already built. And we are.
WH11NE- Sunrise: trying to fully analyze the data, right? So I have done an extensive simulation work for the system right on the design.
WH11NE- Sunrise: But we are still a in need of experimental data to to validate it. Right?
WH11NE- Sunrise: So typically a new Vito would just run the detector
WH11NE- Sunrise: you need. You want for by coverage, right? When I'm young. goes through your detector
WH11NE- Sunrise: it will always have 2 points of interaction, and it's pretty easy to to be doing right, and this the neon.
and
WH11NE- Sunrise: you just need one layer. But the we have a
WH11NE- Sunrise: extra scintillators, right plastic scintillators.
WH11NE- Sunrise: and we came out with this. Multi layer beta system, right where we have multiple layers of plastic simulators. And then we have this great stuff. Here is is which is a material that can capture.
WH11NE- Sunrise: So this would be the spectrum of sorry, the spectrum of
WH11NE- Sunrise: the
WH11NE- Sunrise: going from spectrum high energy less likely.
WH11NE- Sunrise: And this is an example of a simulated event.
WH11NE- Sunrise: As you can see, it's pretty messy. You have a very high energy, energetic, cosmic neutron that produce a lot of secondary neutrons that basically go all over the place.
WH11NE- Sunrise: And at some point some of them may try with the with the tech.
WH11NE- Sunrise: And this
WH11NE- Sunrise: is the new. The planning system
WH11NE- Sunrise: will be capable of detecting these second dynamics on
WH11NE- Sunrise: the
WH11NE- Sunrise: okay. So here would be an example of of 2 2 different Internet. So, for example, this one
WH11NE- Sunrise: would be very easily to to beat up from the there without the information. So even though they haven't this year I did by a primary neutron, the particle that
WH11NE- Sunrise: gets inside the detector itself, maybe an electron, for example, such as this case. And then, if extensive target can be filtered. But in the case of the right, for example, this is a a neutron that is producing appoints right? So it's principle. The energy is right and the position right? It's impossible to differentiate from the why we worry so much about the
WH11NE- Sunrise: and it's the customers.
WH11NE- Sunrise: Yeah, just told me at any time. If you think
WH11NE- Sunrise: so, should I? Should I rub it out? The
WH11NE- Sunrise: yeah. Okay.
WH11NE- Sunrise: And
WH11NE- Sunrise: yeah, so that so you have the very high, energetic neutron E, which has a very low interaction with everything.
WH11NE- Sunrise: It usually goes through the to the plastic scintillators. But it's very likely that it interacts with the system because it's a basic on on this right and with interaction industry. What's the big conference
WH11NE- Sunrise: multiple secondary neutrons are produced with lower energy and a very high amount of these new terms.
WH11NE- Sunrise: And these neutrons.
WH11NE- Sunrise: interact with the system. But they lose a very little energy, because let has a very high atomic number. At some point they they may reach the plastic scintillators, they would lose energy.
WH11NE- Sunrise: This energy would be recorded by the plastic scintillators, but
WH11NE- Sunrise: the energy of a neutron is twice right in comparison to the energy of a by simulation is lower. If it's a neutron interacting, that means it is
WH11NE- Sunrise: so if by adding between the plastic integrators, what we achieve is that once the user is thermalized, it will be captured. and some photons are not points and can be detected by the
WH11NE- Sunrise: by scintillators.
WH11NE- Sunrise: So this is the current strategy to type the
WH11NE- Sunrise: because we need your ads right? So this this diagram of the
WH11NE- Sunrise: simulation event. Right? Then the blue crosses correspond to capture events.
WH11NE- Sunrise: Photos? Right? So that would be significant number of photos.
WH11NE- Sunrise: So this would be, and this would be very.
WH11NE- Sunrise: But if it's in as compared to not using a capture monthly, so there are some.
WH11NE- Sunrise: cabinets about this strategy. So, for example.
WH11NE- Sunrise: if we started the generation time of of these new terms.
WH11NE- Sunrise: we can see that basically, they are produced instantaneously right in a few nanoseconds. All the generation of new terms. So our but this time scale for echoes that give, time? Right? So well, we have the position in our gas.
WH11NE- Sunrise: We need to have an acquisition window that would cover
WH11NE- Sunrise: the 15 from the for this part of our microseconds, right or or a few times of microseconds. So nanosecond is basically instant. However, if we started time for neutron capture, this takes much longer, it takes a
WH11NE- Sunrise: may take up to 100 200 a microsecond, because the termization of the neutrons is somewhat slow, so we need to tune that this is some window
WH11NE- Sunrise: in order to
WH11NE- Sunrise: so accommodate the right. If we have a very short acquisition window, we may miss some intern set events. Background.
WH11NE- Sunrise: So here's an example of the
WH11NE- Sunrise: so yeah, we have overlay the signals from the micro managers. Which are these?
WH11NE- Sunrise: they are. They are same time at the pure time, and then we have
WH11NE- Sunrise: the signals from the metro system. Right? So.
WH11NE- Sunrise: right? So
WH11NE- Sunrise: when there is a signal is usually likely that there are other signals at the same time.
WH11NE- Sunrise: Hey, we can study different ways of recognizing this event. So, for example, we can study special patterns right? So there is
WH11NE- Sunrise: a correlation magic, so different simulators for new events on the left. So it's here admin events will have some special pattern right? This is the pattern on left, and you may think that, neuters would also have some special pattern. But after doing this study, we basically see that it's not the case, right? Efficiency about our reaction versus
WH11NE- Sunrise: yes, efficiency of the system.
WH11NE- Sunrise: We compare the feature of the different bit of the bit of groups. Basically, they are all similar
WH11NE- Sunrise: the top. Most not that much more important, not the bottom, for example, and we study the number of layers efficiency versus the number of layers of the system.
WH11NE- Sunrise: and we reach the conclusion that 3 layers system is the they're most efficient
WH11NE- Sunrise: material. That is significant
WH11NE- Sunrise: improvement in using this, a capture material, so that
WH11NE- Sunrise: in principle, in theory, the study should work right? So
WH11NE- Sunrise: experimental efforts for this are ongoing right? So this is the system I build and currently taking data. And we are on.
WH11NE- Sunrise: And yeah. So the some of my conclusions that the actions are interesting, targets protection. They solve the they may solve the strong city problem. And they also Darwin candidates. And I actually would prove they would probe an important reason of the parameter space.
WH11NE- Sunrise: Yeah. So if this is unique challenges in bugger reduction background of open.
WH11NE- Sunrise: Thank you very much.
WH11NE- Sunrise: Thank you.
WH11NE- Sunrise: Is there any any questions
WH11NE- Sunrise: for the
WH11NE- Sunrise: a signal in this correlation part.
WH11NE- Sunrise: what do you mean? The same. Now, this. Okay, so this is a
WH11NE- Sunrise: yeah.
WH11NE- Sunrise: So that I know what the signal would look like.
WH11NE- Sunrise: Yeah, the actual. So obviously, the action was not producing. So this would only be triggered by background. So I'm pretty simple, depending on the background. Right? So, for example,
WH11NE- Sunrise: there would be a correlation between some features. Right? But typically you would be, there would be seamless, uncorrelated.
WH11NE- Sunrise: How much dead time do you have due to these backgrounds. Is it significant? And
WH11NE- Sunrise: it it it? That's a good question. II don't have a
WH11NE- Sunrise: the numbers for the for this person at the moment, so that that time is not very significant. But when we are talking about the
WH11NE- Sunrise: posting mute on I system, for example.
WH11NE- Sunrise: we need to be careful with this right? Because we need to increase that position. We know this would have some
WH11NE- Sunrise: country house. any other questions
to option.
WH11NE- Sunrise: Okay, thank you very much.
