The KATRIN Search for Neutrino Mass
ORAL
Abstract
The Karlsruhe Tritium Neutrino (KATRIN) experiment is a sensitive probe of the neutrino mass scale, using the kinematics of tritium beta decay to target a design sensitivity of 0.2 eV (90% CL). Since KATRIN's first neutrino-mass results in 2019, which improved the world's best direct limit by a factor of about two, the collaboration has developed new improvements and operational modes to further improve its physics reach. I will give an overview of the current status and progress of the experiment, including a more intense tritium source and reduced backgrounds.
