HOLMES is an experiment to directly measure the neutrino mass with a calorimetric approach. The calorimetric technique eliminates several systematic uncertainties usually present in spectrometers where the external source and decays to excited states affect the measurement. 163Ho is chosen as source for its very low Q value (2.8 keV), the...

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...

The HOLMES experiment aims to directly measure the [Formula presented] mass with a calorimetric approach. The choice of 163 Ho isotope as source is driven by the very low decay Q-value ([Formula presented] 2.8 keV), which allows for high sensitivity with low activities (O(10[Formula presented])Hz/detector), thus reducing the pile-up...

This paper describes the production and chemical separation of the163Ho isotope that will be used in several nuclear physics experiments aiming at measuring the neutrino mass as well as the neutron cross section of the163Ho isotope. For this purpose, several batches of enriched162Er have been irradiated at the Institut Laue-Langevin high flux...

Measuring the neutrino mass is one of the most compelling issues in particle physics. HOLMES is an experiment for a direct measurement of the neutrino mass. HOLMES will perform a precise measurement of the end point of the electron capture decay spectrum of (Formula presented.) in order to extract information on the neutrino mass with a...

The HOLMES experiment will perform a precise calorimetric measurement of the end point of the Electron Capture (EC) decay spectrum of 'Ho in order to extract information on neutrino mass with a sensitivity below 2 eV. In its final configuration, HOLMES will deploy 1000 detectors of low temperature microcalorimeters with implanted Ho-168 nuclei....

HOLMES is an experiment aimed at directly measuring the neutrino mass through the calorimetric measurement of the 163 Ho electron capture decay. The final goal of the project consists in providing a sensitivity on the neutrino mass below 2 eV; in addition, it will establish the potential of this approach to achieve a sub-eV sensitivity. 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 aims to measure the end-point energy of the electron capture (EC) decay of 163Ho with a statistical sensitivity on...
