Description
The Ricochet experiment aims at measuring the coherent elastic neutrino-nucleus scattering (CEνNS) of reactor antineutrinos at the Institut Laue-Langevin, ILL (Grenoble, France). Ricochet employs two detector technologies to measure the CEνNS: (1) germanium cryogenic calorimeters with neutron-transmutation-doped thermistors (called CryoCube); (2) cryogenic calorimeters with a superconducting target and a transition-edge sensor readout (called Q-Array). The CryoCube exploits a combined readout of phonons and ionization to identify nuclear recoil events and reject other backgrounds (electron recoils). The Q-Array will use pulse shape discrimination related to the different timescales of quasiparticle recombination and phonon relaxation for electron- and nuclear-recoils respectively. In 2024, the Ricochet experiment was commissioned at the ILL with a mini-CryoCube detector, composed by three 42-gram germanium detectors. The results in terms of detector performance and background levels achieved during this commissioning phase will be presented in this contribution.
