50. LEGEND-1000 cryostat and cryogenic system

Bernhard Schwingenheuer (MPI Kernphysik)

Invited plenary talk

LEGEND-1000 searches for the neutrinoless double beta decay of Ge-76 by operating germanium detectors in a liquid argon cryostat. The argon surrounding the detectors is from an underground gas source extracted by a method developed by the DarkSide experiment. The talk discusses special features of the cryostat design and the cryogenic infrastructure.

Invited plenary talk

DarkSide-20k is a next-generation detector for the direct search for dark matter, currently under construction at the Gran Sasso National Laboratory (Italy). The experiment employs a dual-phase liquid-argon time projection chamber (TPC) and relies on two distinct types of liquid argon: atmospheric argon, used as a thermal bath and for the muon veto, and ultra-pure underground argon, which...

16. Applications of mK technologies in astroparticle physics: from resolution to exposure frontiers

Dr Paolo Gorla (Laboratori Nazionali del Gran Sasso (INFN) (IT))

Invited plenary talk

In recent years, millikelvin (mK) technologies have undergone remarkable progress, driven both by scientific applications and by rapid developments in quantum-computing industries. Rare-event searches - such as the hunt for the dark-matter content of the universe and investigations into the Majorana nature of the neutrino - continue to push the performance of cryogenic instrumentation to new...
