COBRA is a neutrinoless double-beta-decay experiment using an array of Cadmium-Zinc-Telluride semiconductor detectors, the isotop of interest being Cd-116 with a Q-value of 2814~keV. To investigate the experimental challenges of operating CdZnTe detectors in low background mode and to identify potential background components a demonstrater setup is operated at the Gran Sasso underground...

"The KATRIN experiment is aiming to directly measure the absolute neutrino mass scale from the kinematics of tritium beta-decay. KATRIN is located at KIT (Karlsruhe Institute of Technology) and is currently under construction. The experiment will analyze the shape of the high energy end of the tritium beta-spectrum. A nonzero neutrino mass reduces the endpoint energy and distorts the...

The goal of the MARE project (Microcalorimeter Array for a Rhenium Experiment) is the direct and calorimetric measurement of the electron neutrino mass. The design is based on arrays of thermal detectors to study the beta decay of 187Re and the electron capture (EC) of 163Ho. The measurement of 163Ho EC is an appealing alternative to the 187Re beta decay measurement because few nuclei are...

The determination of the absolute scale of the neutrino masses is one of the most challenging questions in particle physics. Different approaches are followed to achieve a sensitivity on neutrino masses in the sub-eV range. Among them, experiments exploring the beta decay or electron capture of suitable nuclides can provide necessary information on the electron neutrino mass value. In this...

The Project 8 experiment aims to determine the electron neutrino mass by measuring the spectrum of tritium beta decay electrons near the 18.6 keV endpoint. Unlike past tritium experiments, which used electrostatic and magnetostatic spectrometers, Project 8 will detect decay electrons nondestructively via their cyclotron radiation emission in a magnetic field. An individual electron is...
