Zusammenfassung: | Nuclear Inst. and Methods in Physics Research, A 1057 (2023)
168765 Coherent elastic neutrino-nucleus scattering (CE$\nu$NS) offers valuable
sensitivity to physics beyond the Standard Model. The Ricochet experiment will
use cryogenic solid-state detectors to perform a precision measurement of the
CE$\nu$NS spectrum induced by the high neutrino flux from the Institut
Laue-Langevin nuclear reactor. The experiment will employ an array of
detectors, each with a mass of $\sim$30 g and a targeted energy threshold of 50
eV. Nine of these detectors (the "Q-Array") will be based on a novel
Transition-Edge Sensor (TES) readout style, in which the TES devices are
thermally coupled to the absorber using a gold wire bond. We present initial
characterization of a Q-Array-style detector using a 1 gram silicon absorber,
obtaining a baseline root-mean-square resolution of less than 40 eV. |
