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 163Ho in order to extract information on neutrino mass with a sensitivity as low as 04 eV HOLMES in its final configuration will deploy a 1000 pixel array of lowtemperature 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 radiofrequencybased 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
