Results of First Tritium Measurements at the KATRIN Experiment — •Martin Slezák for the KATRIN collaboration — Max Planck Institute for Physics, Munich, Germany
The aim of the Karlsruhe Tritium Neutrino (KATRIN) experiment is to search for the effective electron antineutrino mass with a sensitivity of 0.2 eV/c2 (90 % C.L.) using electrons from tritium β-decay.
First Tritium measurements were taken in Summer 2018 with the goal of commissioning the full KATRIN system with 1 % nominal tritium activity and demonstrating a global system stability on the 0.1 % level. In addition, the data provides the opportunity to investigate the β-spectrum for systematic effects and cross-check the analysis tools and strategies.
This talk gives an overview of the preliminary results from the high-level analysis of First Tritium measurements. In particular, I will discuss different analysis strategies, relevant systematic effects, and stability of the analysis results.
