Optimization and Performance of the CryoCube Detector for the Future Ricochet Low-Energy Neutrino Experiment

The RICOCHET reactor neutrino observatory is planned to be installed at Institut Laue-Langevin starting in mid-2022. scientific goal of the collaboration perform a low-energy and percentage-precision CENNS measurement order explore exotic physics scenarios beyond standard model. To that end, will host two cryogenic detector arrays : CryoCube (Ge target) Q-ARRAY (Zn target), both with unprecedented sensitivity O(10)eV nuclear recoils. composed 27 Ge crystals 38g instrumented NTD-Ge thermal sensor as well aluminum electrodes operated 10mK measure ionization heat energies arising from particle interaction. competitive detector, array designed following specifications low energy threshold ($\sim 50$eV), ability identify reject high efficiency overwhelming electromagnetic backgrounds (gamma, betas, X-rays) sufficient payload 1$kg). After brief introduction future experiment its CryoCube, current works first performance results on optimization channel electrode designs presented. We conclude preliminary estimation signal within RICOCHET.
