Physics Seminar - First results from the KATRIN experiment (neutrino physics)
This is a past event.
Friday, November 13 at 1:00pm to 2:15pmVirtual Event
With Prof. Susanne mertens, Technical University Munich.
Abstract: The Karlsruhe Tritium Neutrino (KATRIN) experiment is designed to directly measure the neutrino mass via the kinematics of tritium beta decays. The neutrino mass manifests itself as a small shape distortion of the beta-decay spectrum close to its endpoint. KATRIN combines a high-activity tritium source with a high-resolution spectrometer of the MAC-E-Filter type. The experiment is designed to reach a sensitivity of 0.2 eV (90%CL) after 1000 days of data taking. In this talk the working principle of KATRIN, the analysis strategy and the challenges will be described in detail. Finally, the first result of KATRIN, setting a new world-leading limit of 1.1 eV (90% CL), will be presented.
