Sensitivity studies of the KATRIN experiment with a differential detector — •Svenja Heyns for the KATRIN collaboration — Institute for Astroparticle Physics, Karlsruhe Institute of Technology
The Karlsruhe Tritium Neutrino Experiment (KATRIN) is designed to probe the neutrino mass with a sensitivity of 0.2 eV/c2 (90% C.L.). The measurement principle relies on an integral measurement of the tritium beta spectrum at the kinematic endpoint of T2 by a high-pass MAC-E-type filter. Switching to a differential measurement of the beta-electron spectrum with eV-scale resolution would increase statistics and allow improved discrimination of background events. This presentation outlines the potential modification to the setup with possible detector concepts and discusses their impact in first studies on neutrino mass sensitivity.
