Neutrino Mass Measurement and Beyond with the KATRIN Experiment

The Karlsruhe Tritium Neutrino (KATRIN) experiment is designed to measure the effective electron anti-neutrino mass with a sensitivity of 0.2 eV (90% CL) via precision spectroscopy of the tritium β-decay spectrum. KATRIN’s current results improved the world’s direct limit of the upper bound to 0.8 eV (90% CL). Further data taking and analysis, and research into background reduction techniques are underway to push KATRIN towards our design goal sensitivity.

In this talk, the results of the neutrino mass measurement by KATRIN will be given, in addition to our path to a sensitivity of 0.2 eV (90% CL). The status of the TRISTAN detector upgrade, to enable KATRIN to search for keV sterile neutrinos, will also be presented.
