Demonstration of a cryogenic, switchable electron source for low-temperature detector calibration

Abstract We present the realization of a prototype of a compact, switchable electron source operating at cryogenic temperatures, demonstrated at energies ranging from 100 eV to 300 eV, and conceptually extendable to an arbitrary energy range. The electrons are produced via photoe...

Probing dark matter interactions with a RES–NOVA prototype cryogenic detector

Abstract We report on the operation of a 13 g PbWO $$_4$$ 4 crystal, grown from archaeological Pb and operated as a cryogenic calorimeter in an underground environment. Read out with a Ge thermistor, the detector achieves a low energy threshold and, for the first time, enables th...
