From KATRIN to TRISTAN: Neutrino mass and sterile neutrinos

KATRIN (Karlsruhe Tritium Neutrino Experiment) is an experiment built to perform a high-statistics and high-resolution measurement of the endpoint region of the Tritium β spectrum, with the main goal of measuring the neutrino mass. KATRIN holds the world-leading limit on the neutrino mass of 0.8 eV as a result of the joint analysis of the first two measurement campaigns. After KATRIN's data taking, a new phase with an upgraded detector, called TRISTAN, is planned. This new detector will sustain a higher count rate, allowing a high-statistics measurement of the whole spectrum. The main target is the search for new physics, like sterile neutrinos with mass in the keV-range, which are candidates to be Dark Matter particles.
