Description
Since its discovery in 2017, interest in Coherent Elastic Neutrino-Nucleus
Scattering (CENNS) has rapidly increased. The precise measurement of CENNS
energy spectrum and cross section opens the possibility of exploring physics
beyond the Standard Model and plays a crucial role in constraining the
background for next-generation dark matter experiments.
Cryogenic detectors are particularly well-suited for observing CENNS due to their
exceptional sensitivity, which allows for the detection of particle interactions at very
low energy thresholds. With this motivation, the RICOCHET experiment aims to
perform a precision measurement of the CENNS spectrum by detecting neutrinos
emitted from the nuclear reactor at the Institut Laue–Langevin in France.
The experiment plans to employ an array of cryogenic thermal detectors using
different technologies: germanium ionization and phonon detectors using Neutron
Transmutation Doped (NTD) thermometers, and superconductor-based detectors
using Transition Edge Sensor (TES) thermometers. In this talk, I will present an
overview of the RICOCHET experiment and discuss its most recent results.
