Characterization of a CsI(Tl) Scintillator Coupled to a SiPM at Cryogenic Temperatures
M. Mirzakhani, R. Mahapatra, M. Platt
We report on the scintillation characterization of a 1 cm^3 CsI(Tl) crystal coupled to a 6 x 6 mm^2 SiPM read out with a custom transimpedance amplifier at cryogenic temperatures.…
Design Studies Of A Pulsed Quasimonoenergetic 2-keV Neutron Source For Calibration Of Low Threshold Dark Matter Detectors
L. Chaplinsky, S. Fiorucci, C. W. Fink +25
We describe design studies for a pulsed quasi-monoenergetic 2-keV neutron source for calibration of sub-keV nuclear recoils. Such a calibration is required for detectors sensitive…
Improved Modelling of Detector Response Effects in Phonon-based Crystal Detectors used for Dark Matter Searches
M. J. Wilson, A. Zaytsev, B. von Krosigk +20
Various dark matter search experiments employ phonon-based crystal detectors operated at cryogenic temperatures. Some of these detectors, including certain silicon detectors used b…
First Demonstration of the HeRALD Superfluid Helium Detector Concept
R. Anthony-Petersen, A. Biekert, C. L. Chang +33
The SPICE/HeRALD collaboration is performing R&D to enable studies of sub-GeV dark matter models using a variety of target materials. Here we report our recent progress on instrume…
Development of a large-mass, low-threshold detector system with simultaneous measurements of athermal phonons and scintillation light
M. Chaudhuri, G. Agnolet, V. Iyer +10
We have combined two low-threshold detector technologies to develop a large-mass, low-threshold detector system that simultaneously measures the athermal phonons in a sapphire dete…
Observation of Time-Dependent Internal Charge Amplification in a Planar Germanium Detector at Cryogenic Temperature
P. Acharya, M. Fritts, D. -M. Mei +4
For the first time, time-dependent internal charge amplification through impact ionization has been observed in a planar germanium (Ge) detector operated at cryogenic temperature.…
Large-mass, low-threshold sapphire detector for rare event searches
S. Verma, S. Maludze, M. Lee +12
Low mass nuclear recoil dark matter and coherent-elastic-neutrino-nucleus-scattering (CENNS) searches confront similar challenges in choosing ultra-low threshold and large-mass det…
A backing detector for order-keV neutrons
A. Biekert, L. Chaplinsky, C. W. Fink +23
We have designed and tested a large-area (0.15~m) neutron detector based on neutron capture on \ce{^{6}Li}. The neutron detector design has been optimized for the purpose of ta…
A novel active veto prototype detector with an inner target for improved rare event searches
M. Chaudhuri, A. Jastram, G. Agnolet +13
We report the fabrication and performance of an annular, cryogenic, phonon-mediated veto detector that can host an inner target detector, allowing substantial reduction in radiogen…
Single Electron-Hole Pair Sensitive Silicon Detector with Surface Event Rejection
Ziqing Hong, Runze Ren, Noah Kurinsky +8
We demonstrate single electron-hole pair resolution in a single-sided, contact-free 1 cm by 1 mm thick Si crystal operated at 48 mK, with a baseline energy resolution of 3 eV.…
