The CMS electromagnetic calorimeter (ECAL) is a homogeneous calorimeter made of about 75000 lead tungstate scintillating crystals. In view of the high-luminosity phase of the LHC, the ECAL readout electronics must be upgraded to cope with the more stringent requirements in terms of trigger latency and rate, as well as the harsh radiation environment and the extreme level of pile-up events,...
As nuclear and high energy facilities around the world are upgraded and move to higher and higher intensities, the detectors in use at these facilities must become more radiation tolerant. Diamond is a material in use at many facilities due to its inherent radiation tolerance and ease of use. In this talk, we will present the results of recent radiation tolerance measurements of the highest...
In the High Luminosity-LHC, the CMS Tracker will deliver data with gigabit rate. The pixel detector will be read out using a custom chip developed by the RD-53 collaboration. Low-mass, high bandwidth electrical links transfer the data at a speed of 1.28 Gbps from the readout chip to a low power gigabit transceiver. This transceiver will further send the serialized data at the rate of 10 Gbps...
The Gigabit Transceiver (GBCR) is one of the ASICs designed for the ATLAS Inner Tracker (ITk) upgrade project. It recovers the high-frequency loss of the data in the transmission cable that brings signals from the pixel readout chip. There are 4 receiver channels, each operating at 5.12 Gbps, and a transmitter channel operating at 2.56 Gbps. The first prototype has been designed and tested...
The Monitored Drift Tube (MDT) detector will be used at the first-level trigger to improve the muon transverse momentum resolution and thus reduce the muon trigger rate for high-luminosity LHC runs. The small-diameter MDT (sMDT), with half the drift-tube diameter of the MDT and using the same readout electronics, will be installed in detector regions where MDT chambers will not fit. A new...
The future PANDA experiment at the Facility for Antiproton and Ion Research (FAIR) in Darmstadt (Germany) is a fixed-target experiment for collisions of antiprotons with a proton target up to a beam momentum of 15 GeV/c and designed to address a large number of open questions in the hadron physics sector.

During the LHC Run-2 operations ATLAS gathered a total of $139~fb^{-1}$ of $pp$ collision data at a center-of-mass energy of $\sqrt{s}=13~$TeV. The uncertainty on the measurement of the total integrated luminosity, $1.7\%$, is the dominant uncertainty for a number of analyses. A precise luminosity measurement is therefore of high importance. In this talk, we provide a description of the...

The DarkSide-20k detector is currently...
To observe signals from low-energy nuclear recoils, including WIMP-xenon scatters, the LZ dark matter detector must maintain strong drift and extraction fields within its dual-phase xenon time projection chamber (TPC). This will be accomplished with a set of four high-voltage grids made of stainless steel wire mesh that are placed at various heights in the TPC. Reaching and holding the grids’...
The Scintillating Bubble Chamber (SBC) is a rapidly developing new technology for sub-keV nuclear recoil detection. Demonstrations in liquid xenon at the few-gram scale have confirmed that this technique combines the event-by-event energy resolution of a liquid-noble scintillation detector with the world-leading electron-recoil discrimination capability of the bubble chamber, and in fact...
Noble liquid detectors have become an attractive option for exploring physics beyond the standard model. Current experiments are using these detectors to search for dark matter interactions, neutrinoless double beta decay, and other phenomena. Improved energy resolution can be leveraged from an optimized combination of two detection channels: ionization and scintillation. Experimentally, a...

Large-scale neutrino detectors deploy a wide variety of technologies, most commonly water, ice, or scintillator targets surrounded by PMTs. The detected photons carry information that goes unused, most notably the wavelength, which can indicate the production method and travel time of the photon. In particular, in scintillator detectors, wavelength can be used to discriminate Cherenkov from...
Though hardware-based trackers were a crucial element of the triggering systems for both D0 and CDF, no such system has yet been incorporated into either ATLAS or CMS. The ATLAS Fast TracKer (FTK) is a first step towards this goal and will provide full tracking information for all events passing ATLAS’s Level-1 trigger in Run 3. This system greatly reduces the CPU required to identify...

The High Luminosity upgraded LHC is expected to deliver proton-proton collisions per 25 ns with an estimated 140-200 pile up interactions per bunch crossing. Ultrafast track finding is vital for handling L1 trigger rates in such conditions. An FPGA-based track trigger system, capable of finding tracks with momenta above 2 GeV is presented.
Position resolution is a key property of the innermost layer of the upgraded ATLAS and CMS pixel detectors for determining track reconstruction and flavor tagging performance. The 11 GeV electron beam at the SLAC End Station A was used to measure the position resolution of RD53A modules with a $50\times50$ and $25\times100\ \mu$m$^2$ pitch. Tracks are reconstructed from hits on telescope...

electron that results from this process can be mimicked by cosmic-ray muons or their
products entering the detector. An active veto detector surrounding the apparatus
is used to detect incoming cosmic-ray muons. To reduce the...
The NuSOL collaboration pursues the physics motivation and detector development for a neutrino detector in space. I will briefly present some of the physics motivation for detecting solar neutrinos at a distance of just a few solar radii from the sun. The environment close to the sun provides very different backgrounds from those present on Earth. I will also discuss some detector design...
Many neutrino mass extensions to the standard model require the neutrino to be a Majorana fermion. If this is the case, the rare process of neutrinoless double beta decay is predicted with half lives greater than about 10^25 years. Many current and future experiments look for this decay by identifying a summed double beta energy at the Q value of the decay, but adding energy and angular...
