During the last couple of decades, the use of arrays of bolometers has represented one of the leading techniques for the search for rare events. CUORE, an array of 988 TeO 2 bolometers that is taking data since April 2017 at the Laboratori Nazionali del Gran Sasso (Italy), exploits the large mass, low background, good energy resolution and low...

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...

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...
