Analysis of First Tritium Data of the KATRIN Experiment — •Christian Karl for the KATRIN collaboration — Max-Planck Institut für Physik

The Karlsruhe Tritium Neutrino (KATRIN) experiment is designed to determine the effective electron anti-neutrino mass with a sensitivity of mν= 0.2 eV/c2 (90 % C.L.) using electrons from tritium β-decay.

First Tritium data was taken in May and June 2018 with the goal of commissioning the full KATRIN system with 1 % nominal activity and demonstrating a global system stability on the 0.1 % level. In addition, this data provides the opportunity to investigate the β-spectrum for systematic effects and test the analysis tools and strategies.

This talk gives an overview of the results from the high-level analysis of First Tritium measurements with a focus on the different analysis strategies as well as a full analysis including systematic effects.
