Description

The Ricochet experiment is an international collaboration that aims at detecting the CEvNS process using germanium crystal calorimeters at cryogenic temperatures. The detectors can simultaneously readout the ionization and heat energies following particle interactions occurring in the crystal. This dual measurement allows to both perform particle identification, i.e. to discriminate between electronic and nuclear recoils, and to determine the recoil energy of the interactions. This poster presents a preliminary study dedicated to measuring the ionisation yield of nuclear recoils at the keV energy scale based on the first Ricochet commissioning data.
