The European Research Council has recently funded HOLMES, a new experiment to directly measure the neutrino mass. HOLMES will perform calorimetric measurement of energy released in decay 163Ho. eliminates systematic uncertainties arising from use external beta sources, as experiments with spectrometers. This was proposed 1982 by A. De Rujula and M. Lusignoli, but only detector technological progress allowed design sensitive experiment. deploy large array low temperature microcalorimeters...
Neutrinoless double beta decay ( $$0\nu \beta $$ ) is one of the most sensitive probes for physics beyond Standard Model, providing unique information on nature neutrinos.

We summarize recent advances in background suppression demonstrated using bolometers with simultaneous readout heat light signals. simulate several configurations a future CUORE-like bolometer array which would utilize these improvements present sensitivity...
