Particle Physics:
– Member of the next Enriched Xenon Observatory (nEXO) collaboration, for the study of neutrinoless double beta decay. International collaboration of more than 150 scientists with a planned budget of 250 M$USD. Realization of 3DdSiPM operated at the cryogenic temperature of liquid xenon.
– Production of 3DdSiPM for the study of dark matter, operated at cryogenic temperature in liquid argon.
Quantum sensor:
Realization of a 3DdSiPM for the distribution of quantum keys between the earth and a satellite.
