A compact beta particle momentum detector
D. Kodroff, M. Hu, K. Adcock +8
We present the design, development, and first calibration results of a compact beta electron detector for the Quantum Invisible Particle Sensor (QuIPS) experiment. The QuIPS electr…

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…

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…
