The idea of measuring the coherent elastic nuclear scattering of neutrinos emitted by a high intensity 51Cr radioactive source is investigated. To produce the high intensity source, the radioactive material used in the GALLEX experiment (36 kg of Chromium 38.6% enriched in 50Cr) could be reactivated to an intensity of few MCi. The advantages of...

Searches for new physics in the coherent elastic neutrino-nucleus scattering require a precise knowledge of the neutrino flux and energy spectrum. In this paper we investigate the feasibility and the performance of an experiment based on a Cr-51 source, whose neutrino spectrum is known and whose activity can be heat-monitored at few permil...

The CUPID-0 experiment searches for neutrinoless double beta decay using the first array of enriched Zn82Se scintillating bolometers with double (heat and light) read-out. To further enhance the CUPID-0 detector performances, the heat-light correlation has been exploited to improve the energy resolution. Different decorrelation algorithms have...

The production of ultra-pure raw material is a crucial step to ensure the required background level in rare event searches. In this work, we establish an innovative technique developed to produce high-purity (99.999%) granular zinc. We demonstrate the effectiveness of the refining procedure by measuring the internal contaminations of the...
