We report on the development of thermal kinetic inductance detectors (TKIDs) suitable to perform X-ray spectroscopy measurements. The aim is to implement MKIDs sensors working in thermal quasi-equilibrium mode to detect X-ray photons as pure calorimeters. The thermal mode is a variation on the MKID classical way of operation that has generated...

HOLMES is a new experiment aiming at directly measuring the neutrino mass with a sensitivity below 2 eV . HOLMES will perform a calorimetric measurement of the energy released in the decay of163Ho. The calorimetric measurement eliminates systematic uncertainties arising from the use of external beta sources, as in experiments with...

The main goal in the HOLMES experiment is the neutrino mass measurement using an array of 1000micro-calorimeters with standard metallic absorber. A good isotope for such measurement is the163Ho, those isotopes embedded in the metallic absorber will be 1011-1013. Since163Ho is not available in nature, a dedicated process must be set up to...

The European Research Council has recently founded HOLMES, an experiment for a direct neutrino mass measurement with a sensitivity as low as 0.4 eV. HOLMES will perform a calorimetric measurement of the the energy released in the Electron Capture (EC) spectrum of 163Ho. The neutrino mass is assessed from the end point of the spectrum; the...

The determination of the neutrino mass is an open issue in modern particle physics and astrophysics. The direct mass measurement is the only theory-unrelated experimental tool capable to probe such quantity. The HOLMES experiment will measure the end-point energy of the electron capture decay of163Ho, aiming at a statistical sensitivity on the...
