A bolometric detector array to prepare a next generation neutrinoless double beta decay experiment of 100Mo – CUPID-1

The aim of the CUPID-1 project is the development of a complete bolometric detector system capable of investigating neutrinoless double beta decay – 2b0n- with unprecedented sensitivity. The project will be dedicated to the design of a detector tower capable to be operated in a next generation 2b0n experiment at the ton scale and to test one of these towers as a final validation of the technology. The crucial innovative feature of the project is to fully develop and optimize an integrated bolometric system combining thermal and mechanical considerations, optimization of light collection, MC simulations and selection of radiopure materials, including an extensive cryogenic tests campaign, that will allow to reach the background goal below 10-4 counts/(keV kg y). This single tower will be also a competitive 2ß0n experiment at the international level and the most sensitive ever for 100Mo.
