Description
Neutrino oscillation experiments have proven that neutrinos are massive particles, nevertheless the
assessment of their absolute mass scale is still an outstanding challenge in today particle physics
and cosmology. The experiments dedicated to effective electron-neutrino mass determination are
the ones based on the study of nuclear processes involving neutrino, like single beta decay and
electron capture decay. The end-poin measurement of 163Ho EC is an appealing alternative respect
to the single beta decay because fewer nuclei are needed and it is a self-calibrating measurement.
Although the calorimetric measurement of the energy released in the EC decay of 163Ho was
proposed in 1982 by A. Rujula and M. Lusignoli, only recent detector technological progresses have
allowed to design a sensitive experiment. Nowadays the two experiments dedicated to this delicate
measurement are ECHO and HOLMES. This contribution gives an outlook for both experiments
underling their technical challenges and perspectives.
