Abstract Cryogenic single-particle detectors are devices, operated close to absolute zero, widely used in current and future generation for the search rare particle physics processes, example neutrino-less double beta decay. Traditionally, these assembled copper structures inside dilution refrigerators. The use of copper, however, is expected become a limiting factor on path towards background reduction needed projects. Its high density large Z make it an effective target where gamma-rays...

Core-collapse supernovae (SN) mark the end of life massive stars (>8 $M_{\odot}$). Such a process leads to emission high-intensity flux all-flavor (anti-)neutrinos, with $\sim$10$^{58}$ $\nu$ ejected within time window $\simeq$10 s. SN-neutrinos carry away large fraction binding energy progenitor star, and they are direct probe stellar core. Therefore their detection would provide insights about many processes happening during core collapse star SN explosion. RES-NOVA aims deploy first...
Many of the most sensitive physics experiments searching for rare events, like neutrinoless double beta ($0\nu\beta\beta$) decay and dark matter interactions, rely on cryogenic macro-calorimeters operating at mK-scale. Located underground Gran Sasso National Laboratory (LNGS), in central Italy, CUORE (Cryogenic Underground Observatory Rare Events) is one leading search $0\nu\beta\beta$ decay, implementing low-temperature calorimetric technology. We present a novel multi-detector analysis to...

Abstract The Cryogenic Underground Observatory for Rare Events (CUORE) is the most sensitive experiment searching neutrinoless double-beta decay (0 νββ ) in 130 Te. CUORE uses a cryogenic array of 988 TeO 2 calorimeters operated at ∼10 mK with total mass 741 kg. To further increase sensitivity, detector response must be well understood. Here, we present non-linear thermal model on detector-by-detector basis. We have examined both equilibrium and dynamic electro-thermal models detectors by...
One of the most energetic events in Universe are core-collapse Supernovae (SNe), where almost all star's binding energy is released as neutrinos. These particles direct probes processes occurring stellar core and provide unique insights into gravitational collapse.

Pb offers highest neutrino interaction cross-section via coherent...
