MicroBooNE is a Liquid Argon Time Projection Chamber (LArTPC) neutrino experiment on the Booster Neutrino Beamline at the Fermi National Accelerator Laboratory, with an 85-tonne active mass.
One of MicroBooNE’s primary physics goals is to investigate the excess of electron neutrino events seen by MiniBooNE in the [200-600] MeV range.
MicroBooNE will constrain the intrinsic electron neutrino...
The baseline detection technique for IAXO and BabyIAXO consist of an ultra-low background Time Projection Chamber (TPC) coupled to pixelated Micromegas readout. Microbulk Micromegas detectors show convenient features for solar axion searches because their performance is very stable, they present good energy resolution in the IAXO range of interest, they provide topological information of the...
We are going to present the project for CYGNO, a 1kg gaseous TPC Dark Matter directional experiment, to be hosted at Laboratori Nazionali del Gran Sasso. CYGNO (a CYGNus TPC with Optical readout) fits into the context of the wider CYGNUS collaboration, for the development of a Galactic Nuclear Recoil Observatory at the ton scale with directional sensitivity. The most innovative CYGNO's...
We must know that everything we can’t see or feel, we cannot say that it does not exist. And everything we see or feel, we can't always tell what or how it is made.
The mass, by definition, is a measure of resistance of an object to acceleration when a force is applied.
And, in principle, the mass occupies space and it is there where the force takes effect. Given what has been said, Dark...
NEWS-G (New Experiments With Spheres-Gas) is a direct dark matter detection experiment using Spherical Proportional Counters (SPCs). Key advantages of SPCs for dark matter search and especially light mass DM particles are their low energy threshold -single ionisation electron- and the possibility to use various light target nuclei -Neon/Helium/CH4 gases-. Dark
matter limits were obtained in...
Low BG TPC is a powerful tool for direction-sensitive dark matter search.
I will present our R&D of negative ion TPC, TPC with resistive sheet, and latest NEWAGE results.
I'll also cover an international collaborative activity "CYGNUS".
The high signal amplification factors achievable by multi-layer amplification stages of Gaseous Electron Multipliers (GEMs) and the possibility to record scintillation light emitted during avalanche multiplication with high-granularity imaging sensors makes optical readout of GEM-based detectors an attractive technology for Time Projection Chambers (TPCs). Optically read out GEM-based TPCs...
The Deep Underground Neutrino Experiment (DUNE) is an international long-baseline neutrino experiment that will build an intense neutrino beam from Fermi National Accelerator Laboratory in Batavia, Illinois, to a far detector consisting of four Liquid Argon Time Projection Chambers (LAr-TPC) holding in total around 80 ktons, at the Sanford Underground Research Laboratory in South Dakota at...
The International Axion Observatory (IAXO) is the proposed fourth generation axion helioscope, aiming to improve the sensitivity of the currently most sensitive, third generation experiment (CAST) by more than one order of magnitude. This sensitivity is expected to come from an axion-physics dedicated magnet equipped with x-ray focusing devices that will be coupled to low-background detectors....
The Deep Underground Neutrino Experiment (DUNE) will use a large liquid argon (LAr) detector consisting of four modules each with a fiducial mass of 10 kt of LAr. One of the technology options for the far detector modules is a liquid-argon TPC working in dual phase mode.
ProtoDUNE Dual Phase is a large demonstrator of the double phase liquid argon Time Projection Chamber (TPC) with a...
We will discuss the status of the NEXT project including a summary of the recent results obtained with the NEW demonstrator and an overview of the plans for NEXT-100 and beyond.
Noble liquid radiation detectors have long been afflicted by spurious electron emission from their cathodic electrodes. This phenomenon must be understood and mitigated in the next generation of liquid xenon (LXe) experiments searching for WIMP dark matter or neutrinoless double beta decay, and in the large liquid argon (LAr) detectors for the long-baseline neutrino programmes. We present a...
Since the original detection of core-collapse supernova neutrinos in 1987, all large neutrino experiments seek to detect the neutrinos from the next nearby supernova. Among them, liquid argon time projection chambers (LArTPCs) offer a unique sensitivity to the electron neutrino flux. However, the low energy of the events (scale of MeVs), and the fact that all large (multi-tonne) LArTPCs...
