Cryogenic sensors are used in experiments to detect low-energy nuclear recoils from dark matter or neutrino interactions through coherent neutrino scattering. Besides the record energy thresholds, the limit of current technologies resides mainly in the scale-up capabilities.
BULLKID is a R&D supported by INFN. It is developing a new detector concept to reach relatively high target masses...
The CUORE Upgrade with Particle ID (CUPID) is a next-generation neutrinoless double-beta decay experiment that will require cryogenic light detectors to improve background suppression by reading out both the heat and light signals from the scintillating crystals. In this work, we describe a light detector based on a novel Ir/Pt bi-layer transition edge sensor for the first time. We have...
Weakly bound semiconductor materials, Cs3Sb and Ag-O-Cs (photocathodes), have low electron-hole pair energies=Eg+Ea.These semiconductors in shapes and volumes could be used as detectors for: (1) low energy depositions, with thresholds as low as ~50 eV depositions when cooled to ≤4°K(Ag-O-Cs), and (2) applications of Cs3Sb to calorimetry or tracking, with a pair energy 1.8-2 eV, but with far...
I describe the Cryogenic Underground TEst (CUTE) facility at SNOLAB. The facility includes an operating dilution refrigerator that can acheive stable operations at 12 mK base temperature. The CUTE facility also includes shielding from ionizing radiation, both from the SNOLAB ground and from the dilution unit of the refrigerator. There are also technologies to isolate the experimental stages...
The Cryogenic Underground Observatory for Rare Events (CUORE) experiment is an ongoing search for neutrinoless double beta decay located at the Gran Sasso National Laboratory (LNGS) in Italy. Recent work has found that the CUORE calorimeters are sensitive to acoustic and seismic events originating from outside the detector at LNGS. To measure the effect of these mechanical disturbances on the...
