چکیده
P. Gorla Laboratori Nazionali del Gran Sasso, I-67010, Assergi (L’Aquila), Italy Abstract We present the results obtained in the development of scintillating Double Beta Decay bolometers. Several Mo and Cd based crystals were tested with the bolometric technique. The scintillation light was measured through a second independent bolometer. A 140 g CdWO4 crystal was run in a 417 h live time measurement. Thanks to the scintillation light, the α background is easily discriminated resulting in zero counts above the 2615 keV γ line of Tl. These results, combined with an extremely easy light detector operation, represent the first tangible proof demonstrating the feasibility of this kind of technique.

Characterization of a ZnSe scintillating bolometer prototype for neutrinoless double beta decay search
As proposed in the LUCIFER project, ZnSe crystals are attractive materials to realize scintillating bolometers aiming at the search for neutrinoless double beta decay of the promising isotope 82Se. However, the optimization of the ZnSe-based detectors is rather complex and requires a wide-range investigation of the crystal features: optical properties, crystalline quality, scintillation yields ...

متن کاملLUMINEU: a search for neutrinoless double beta decay based on ZnMoO4 scintillating bolometers
The LUMINEU is designed to investigate the possibility to search for neutrinoless double beta decay in Mo by means of a large array of scintillating bolometers based on ZnMoO4 crystals enriched in Mo. High energy resolution and relatively fast detectors, which are able to measure both the light and the heat generated upon the interaction of a particle in a crystal, are very promising for the re...

Luminescent bolometers are double-readout devices able to measure simultaneously the phonon and the light yields after a particle interaction in the detector. This operation allows in some cases to tag the type of the interacting quantum, crucial issue for background control in rare event experiments such as the search for neutrinoless double beta decay and for interactions of particle dark mat...

The R&D activity performed during the last years proved the potential of ZnSe scintillating bolometers to the search for neutrino-less double beta decay, motivating the realization of the first large-mass experiment based on this technology: CUPID-0. The isotopic enrichment in 82Se, the Zn82Se crystals growth, as well as the light detectors production have been accomplished, and the experiment ...
