DOIAbstract
HOLMES is an experiment aimed at directly measuring the neutrino mass through the calorimetric measurement of the 163 Ho electron capture decay. The final goal of the project consists in providing a sensitivity on the neutrino mass below 2 eV; in addition, it will establish the potential of this approach to achieve a sub-eV sensitivity. The detectors performances play a crucial role in achieving the desired sensitivity. Indeed, for such an experiment, the following characteristics are required: short response time ([Formula presented]) to solve pile-up events, great energy resolution ([Formula presented]1 eV @ 2.8 keV) and compatibility to be multiplexed in large detector arrays ([Formula presented]1000). HOLMES will deploy 1000 Transition ...
