- Abstract
Measuring the neutrino mass is one of the most compelling issues in particle physics. The European Research Council has funded HOLMES, a new experiment for a direct measurement of neutrino mass that started in 2014. HOLMES will perform a precise measurement of the end point of the Electron Capture decay spectrum of $$^{163}$$ Ho in order to extract information on neutrino mass with a sensitivity as low as 0.4 eV. HOLMES, in its final configuration, will deploy a 1000 pixel array of low-temperature microcalorimeters: each calorimeter consists of an absorber, where the Ho atoms will be implanted, coupled to a transition edge sensor thermometer. The read out for an array of 1000 cryogenic detectors is a crucial matter: for HOLMES, a special radio-frequency-based multiplexing system is being developed. In this contribution, we outline the performance and special features of the multiplexing system and readout methods chosen for HOLMES.
