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…
Modeling the Differential Rate for Signal Interactions in Coincidence with Noise Fluctuations or Large Rate Backgrounds
Xinran Li, Matt Pyle, Bernard Sadoulet
The characteristic energy of a relic dark matter interaction with a detector scales strongly with the putative dark matter mass. Consequently, experimental search sensitivity at th…
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…
A Transition Edge Sensor Operated in Coincidence with a High Sensitivity Athermal Phonon Sensor for Photon Coupled Rare Event Searches
Roger K. Romani, Yen-Yung Chang, Rupak Mahapatra +6
Experimental searches for axions or dark photons that couple to the standard model photon require photosensors with low noise, broadband sensitivity, and near zero backgrounds. Her…
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…
