Description
The RICOCHET experiment aims to perform a precision measurement of coherent elastic neutrino-nucleus scattering (CE$\nu$NS) at the Institut Laue-Langevin (ILL) research nuclear reactor. While the ILL reactor provides a 4 order of magnitude larger antineutrino flux relative to spallation sources such as the SNS, these antineutrinos are more challenging to detect due to their 10x lower energy. To meet the challenges of this measurement the RICOCHET collaboration has installed an array of 18 cryogenic germanium detectors 8.8 m from the reactor core, each instrumented with a dual heat and ionization readout. This array provides the energy sensitivity required to detect reactor antineutrinos, enables event-by-event particle identification for mitigating backgrounds, all while achieving 750 g of target mass. Ricochet has completed commissioning and began its science phase in July of 2025. This poster will discuss the commissioning results, as well as progress towards first estimates of CEvNS sensitivity.
