Study of superconducting and magnetic microcalorimeters for a high sensitivity neutrino mass measurement experiment — •Loredana Gastaldo^1,2 and Daniel Haug¹ — ¹Kirchhoff Institute for Physics, Im Neuenheimer Feld 227, D-69120 Heidelberg, Germany — ²University and INFN Genoa, Via Dodecaneso 33, I-16146 Genoa, Italy

Since the neutrino oscillation experiments have proved that neutrinos are massive particles, the question if it is possible to determine its absolute value can be addressed with a very high precision β decay experiment. An international collaboration is growing around the project of Microcalorimeter Arrays for a Rhenium Experiment (MARE) for measuring the neutrino mass with a sensitivity of about 0.2eV/c². Here we present the status of the development of superconducting and magnetic low temperature microcalorimeters for the detection of ¹⁸⁷Re beta decay.
