Mo-100-enriched Li2MoO4 scintillating bolometers for 0 nu 2 beta decay search: from LUMINEU to CUPID-0/Mo projects
Original language description
A scintillating bolometer technology based on Mo-100-enriched lithium molybdate (Li-2 (MoO4)-Mo-100) crystals has been developed by LUMINEU to search for neutrinoless double-beta (0 nu 2 beta) decay of Mo-100. The results of several low temperature tests at underground environments have proved the reproducibility of high detector performance and crystal radiopurity: in particular similar to 5-6 keV FWHM energy resolution and at least 9 sigma rejection of alpha's in the vicinity of the 0.2 beta decay of Mo-100 (3034 keV) and below 10 mu Bq/kg bulk activity of Th-228 and Ra-226. A modest acquired exposure (0.1 kgxyr) is a limiting factor of the LUMINEU experiment sensitivity to the 0 nu 2 beta decay half-life of Mo-100 (T-1/2 >= 0.7x10(23) yr at 90% C.L.), however the two-neutrino 2 beta decay has been measured with the best up to-date accuracy, T-1/2 = [6.92 +/- 0.06(stat.) +/- 0.36(syst.)] x 10(18) yr. The applicability of the LUMINEU technology for a tonne-scale 0.2 beta decay bolometric project CUPID is going to be demonstrated by the CUPID-0/Mo experiment with similar to 5 kg of Mo-100 embedded in forty 0.2 kg Li-2 (MoO4)-Mo-100 scintillating bolometers. A first phase of the experiment with twenty Li-2 (MoO4)-Mo-100 detectors is in preparation at the Modane underground laboratory (France) to start by the end of 2017.
