60. Reactor neutrinos at CONNIE: the Multi-Chip Module upgrade

Nicolás Avalos (LPNHE - IN2P3 - CNRS)

14/07/2026, 09:00

The Coherent Neutrino-Nucleus Interaction Experiment (CONNIE) has been using Skipper-CCDs with the aim of detecting CEvNS near the Angra-2 reactor since 2021. These detectors have demonstrated exceptional sensitivity to low-energy ionization signals thanks to their sub-electron resolution and ultra-low noise performance. Recent analyses with reactor data have produced competitive limits on...

8. Probing Neutrino Electromagnetic Interactions and CE$\nu$NS with sub-keV Threshold Germanium Detectors at KSNL

Germanium ionization detectors with their unique features and diverse applications in fundamental research are novel candidates for studies of neutrino electromagnetic interactions ($\nu EM$) as well as coherent elastic neutrino-nucleus scattering (CE$\nu$NS). The TEXONO collaboration aims at progressively improving the sensitivities towards $\nu EM$, CE$\nu$NS and physics beyond the Standard...

13. The NUCLEUS experiment at Chooz: commissioning status and CEνNS prospects

Elisabetta Bossio (CEA Paris-Saclay)

The NUCLEUS experiment aims to detect nuclear recoils at the O(10 eV) scale induced by coherent elastic neutrino–nucleus scattering (CE$\nu$NS) using gram-scale CaWO$_4$ cryogenic calorimeters. Its uniquely low energy threshold provides direct sensitivity to the low-energy part of the reactor neutrino spectrum, setting it apart within the current CE$\nu$NS experimental landscape.
Following a...

18. High precision characterization of the response of cryogenic detectors to sub-keV nuclear recoils

David Lhuillier (CEA Saclay)

14/07/2026, 10:00

The CRAB (Calibrated Recoil for Accurate Bolometry) experiment leverages radiative neutron capture to calibrate the response of cryogenic detectors to nuclear recoils. This method inherently provides high measurement precision in the low-energy range (100–1000 eV) of interest for CEvNS event detection. In this presentation, we describe the dedicated experimental setup installed at the TRIGA...
