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…
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…
Low-Energy Backgrounds in Solid-State Phonon and Charge Detectors
Daniel Baxter, Rouven Essig, Yonit Hochberg +5
Solid-state phonon and charge detectors probe the scattering of weakly interacting particles, such as dark matter and neutrinos, through their low recoil thresholds. Recent advance…
