Progress Towards the RICOCHET Experiment

The RICOCHET experiment is a reactor neutrino observatory aiming to make a precision measurement of the coherent elastic neutrino-nucleus scattering process. Towards this goal, RICOCHET will deploy two cryogenic detector payloads: the CryoCube and the Q-Array. The CryoCube consists of Ge crystals, each weighing 38 g and instrumented with both electrodes and a neutron-transmutation-doped thermistor to measure ionization and heat respectively. The simultaneous measurement of ionization and heat allows for background reduction through the identification of electron and nuclear recoils on an event-by-event basis. The Q-Array will utilize superconducting targets (such as Al, Sn, and Zn) with a transition-edge sensor readout, aiming to use the timing of quasiparticle and phonon dynamics for electron and nuclear recoil identification. This past winter the RICOCHET cryostat and three Ge detectors (the MiniCryoCube) were installed at the Institut Laue Langevin in Grenoble, France. This presentation will highlight the status of the RICOCHET experiment.
