Low Energy Phonon Bursts Created By Fast Neutron Damage
A. Armatol, C. Augier, L. Bergé +67
Solid state athermal phonon calorimeters used in the search for low mass dark matter or coherent neutrino-nucleus interactions have long observed a large excess of events below sev…
Spontaneous generation of athermal phonon bursts within bulk silicon causing excess noise, low energy background events and quasiparticle poisoning in superconducting sensors
C. L. Chang, Y. -Y. Chang, M. Garcia-Sciveres +25
Solid state phonon detectors used in the search for dark matter and coherent neutrino nucleus interactions (CENS) require excellent energy resolution (eV-scale or below) and lo…
First Limits on Light Dark Matter Interactions in a Low Threshold Two Channel Athermal Phonon Detector from the TESSERACT Collaboration
C. L. Chang, Y. -Y. Chang, L. Chaplinsky +45
We present results of a search for spin-independent dark matter-nucleon interactions in a 1 cm by 1 mm thick (0.233 gram) high-resolution silicon athermal phonon detector opera…
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…
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 +24
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…
