Coherent elastic neutrino-nucleus scattering detection at a reactor with RICOCHET
ORAL
Abstract
The Ricochet experiment aims to detect coherent elastic neutrino-nucleus scattering (CEvNS) at the Institut Laue-Langevin nuclear reactor in Grenoble, France.
The experiment is expected to start data-taking in 2024 with two complementary detector technologies, both employing cryogenic calorimeter arrays:
CryoCube (Germanium) and Q-Array (superconducting crystals).
CryoCube comprises 30g Ge crystals instrumented with NTD-Ge thermal sensors and aluminium electrodes,
measuring the heat and ionization arising from particle interactions.
These detectors have demonstrated a low energy threshold (~50 eV),
enabling them to probe into unexplored CEvNS recoil energies with new physics sensitivity.
Meanwhile, Q-Array aims to lower the threshold further by developing superconducting calorimeters,
exploiting the rich phonon and quasi-particle physics to gain particle identification capabilities
and discriminate between electron and nuclear recoil events.
This talk will highlight the first demonstration of 30 eVee ionization energy resolution
with Ricochet germanium cryogenic bolometers and present the path towards
lowering the threshold in future generations using superconducting technologies.
