Development of microwave-multiplexed superconductive detectors for the HOLMES experiment

Understand

In recent years, the progress on low temperature detector technologies has allowed design of large scale experiments aiming at pushing down the sensitivity on the neutrino mass below 1\,eV.

• Even with outstanding performances in both energy ($\sim$eV on keV) and time resolution ($\sim 1\,\mu$s) on the single channel, a large number of detectors working in parallel is required to reach a sub-eV sensitivity.
• HOLMES is a new experiment to directly measure the neutrino mass with a sensitivity as low as 2\,eV.
• HOLMES will perform a calorimetric measurement of the energy released in the electron capture (EC) decay of 163Ho.
