22. Performance of novel VUV-sensitive Silicon Photo-Multipliers for nEXO

Giacomo Gallina (member@princeton.edu;staff@princeton.edu;employee@princeton.edu)

WG7: Photon Detectors (incl. CCDs)

Contribution Talk

Liquid xenon time projection chambers are promising detectors to search for neutrinoless double beta decay (0$\nu \beta \beta$), due to their response uniformity, monolithic sensitive volume, scalability to large target masses, and suitability for extremely low background operations. The nEXO collaboration has designed a five-tonne time projection chamber that aims to search for 0$\nu \beta...

56. Smart pixels with data reduction at source

WG6: TDAQ and AI/ML

Contribution Talk

Highly granular pixel detectors allow for increasingly precise measurements of charged particle tracks, both in space and time. A reduction in pixel size by a factor of four in next-generation detectors will lead to unprecedented data rates, exceeding those foreseen at the High Luminosity Large Hadron Collider. Signal processing within one bunch crossing clock cycle and smart data reduction...

70. Development of ultrafast silicon sensors for precision timing and 4D tracking

Jennifer Ott (University of California, Santa Cruz (US)), Yuzhan Zhao (SCIPP, UCSC)

WG1: Solid State Detectors and ASICs

Contribution Talk

Low Gain Avalanche Detectors (LGADs) are thin silicon detectors with moderate internal signal amplification, providing time resolution of <20 ps for minimum ionizing particles. LGADs are the key silicon sensor technology for the timing detectors of the CMS and ATLAS experiments in the High-Luminosity LHC. In addition, their fast rise time and short full charge collection time (as low as 1 ns)...

171. Camera Readout and Barium Tagging (CRAB) for Neutrinoless Double Beta Decay

Dr Leslie Rogers (ANL)

30/11/2022, 17:00

WG3: Noble Element Detectors

Contribution Talk

Finding evidence of neutrinoless double beta decay would reveal the Majorana nature of the
neutrino and give insight into the origins of the matter-antimatter asymmetry in the universe,
the smallness of neutrino mass, and the symmetry structure of the Standard Model. The NEXT
collaboration is developing a sequence of high pressure xenon gas time projection chambers
with the aim of creating...

99. Deep learning for improved directional sensitivity to low-energy nuclear recoils in gas TPCs

Jeffrey Schueler (University of Hawaii)

30/11/2022, 17:20

WG5: MPGDs

Contribution Talk

Recoil-imaging gas TPCs with MPGD charge readout are promising detector candidates for directional dark matter searches beneath the neutrino fog. In a future directional dark matter detector, head/tail recognition efficiency is expected to be one of the most important performance metrics for using directionality to reject solar neutrino backgrounds and establish the galactic origin of dark...

34. Development of cryogenic optical beam steering for characterization of novel dark matter detectors

Kelly Stifter (Fermilab)

30/11/2022, 17:40

WG4: Quantum and Superconducting Detectors

Contribution Talk

A major hurdle in searches for sub-GeV particle-like dark matter is demonstrating sufficiently low energy detection thresholds in order to detect recoils from light dark matter particles. Many detector concepts have been proposed to achieve this goal, which often include novel detector target media or sensor technology. A universal challenge in understanding the signals from these new...

46. Timing Performance of an Ultra Compact Radiation-Hard Calorimeter Concept: RADiCAL

Carlos Perez Lara (member@virginia.edu;employee@virginia.edu;staff@virginia.edu)

WG2: Calorimetry

Contribution Talk

We are conducting R&D on advanced calorimetry techniques based on scintillation and wavelength-shifting technologies and photosensor (SiPM and SiPM-like) technology. In particular, we are focusing our attention on ultra-compact radiation hard EM calorimeters, based on modular structures (RADiCAL modules) consisting of alternating layers of very dense absorber and scintillating plates, read out...
