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 low…
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…
Low Energy Backgrounds and Excess Noise in a Two-Channel Low-Threshold Calorimeter
Robin Anthony-Petersen, Clarence L. Chang, Yen-Yung Chang +29
We describe observations of low energy excess (LEE) events, background events observed in all light dark matter direct detection calorimeters, and noise in a Transition Edge Sensor…
