Description
The RICOCHET collaboration aims to observe coherent elastic neutrino-
nucleus scattering (CEνNS) to reveal deviations in the electroweak sector from the Standard Model of particle physics. The setup is located 8.8m from the core of the research reactor at the Institut Laue-Langevin (Grenoble, France). The RICOCHET experiment employs germanium-based cryogenic calorimeters, called CryoCube, which can identify particles interactions in the crystal based on a dual measurement of phonon and ionization signals, allowing discrimination between electronic and nuclear recoils, as well as non-ionising events. RICOCHET began its first science phase in July 2025 with its full payload of 18 detectors, corresponding to a total mass of 0.75 kg of germanium. This poster presents the initial on-site energy calibration data of the 18-detector array.
