Dark Matter Detection Using Phonon Sensing in Amorphous Materials
Itay M. Bloch, Simon Knapen, Xinran Li +2
We present a concept for a tabletop-scale detector with an amorphous target designed to search for dark matter absorption into phonon excitations. In crystalline materials, absorpt…

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…

Low Tc Hafnium Kinetic Inductance Device with High Internal Quality Factor
Xinran Li, Aritoki Suzuki, Maurice Garcia-Sciveres
Kinetic inductance devices (KIDs) are superconducting resonators with high kinetic inductance sensitive to external energy perturbations. KIDs made with superconductors having $T_c…
