The 1-ton-scale CUORE detector is made of 988 TeO2 crystals operated as cryogenic bolometers at a working temperature of similar to 10mK. In order to provide the necessary cooling power at 4 K stage, a total of five pulse tube (PT) refrigerators are used. The PTs make the cryogenic system reliable and stable, but have the downside that...

The HOLMES experiment aims to directly measure the v mass studying the 163Ho electron capture decay spectrum, using arrays of TES-based micro-calorimeters implanted with O(102 Bq/detector) 163Ho atoms. The neutron irradiation of 162Er enriched samples, used for the production of 163Ho, also generates radioactive contaminants. Chemical processes...

The HOLMES experiment aims to directly measure the nu mass studying the Ho-163 electron capture decay spectrum developing arrays of TES-based microcalorimeters implanted with O(300 Bq/detector) Ho atoms. The embedding of the source inside detectors is a crucial step of the experiment. Because the Ho-163 production process (neutron irradiation...
