DESCRIPTION:Speakers: Elisabetta Bossio (CEA - Paris Saclay)\n\nCryogenic 
 detectors are opening new opportunities for neutrino physics and rare-even
 t searches thanks to their exceptionally low energy thresholds. In this se
 minar\, I will present recent progress in two complementary efforts: the N
 UCLEUS and CRAB experiments.\nThe NUCLEUS experiment aims to detection of 
 100 eV nuclear recoils induced by coherent elastic neutrino–nucleus scat
 tering using CaWO4 gram-scale cryogenic calorimeters. Following a successf
 ul commissioning campaign at TUM in summer 2024\, the experiment is curren
 tly being installed and commissioned at the Chooz nuclear power plant in F
 rance\, where it will be exposed to an intense reactor neutrino flux. I wi
 ll discuss the current status of this commissioning phase\, including the 
 main challenges and first performance results\, and present the expected p
 hysics reach for the upcoming data-taking phases. \nIn parallel\, the CRA
 B experiment uses neutron capture to study the nuclear recoil response of 
 cryogenic detectors with high precision\, a key ingredient for the interpr
 etation of CEνNS measurements and dark-matter searches. I will present ou
 r latest results obtained with CaWO₄ and Al₂O₃ detectors. In additio
 n to determining the nuclear energy scale with %-level accuracy in the few
  100 eV energy range\, I will discuss a systematic comparison with the ele
 ctronic recoil response. \nzoom connection: https://cern.zoom.us/j/674250
