Description

The determination of the neutrino mass in the KATRIN experiment relies on the magnetic adiabatic collimation with electrostatic filtering (MAC-E filter) technique. A precise knowledge of the electric potential in the source region is essential for achieving the experiment’s targeted sensitivity. Metastable krypton-83 (83mKr) is used as a calibration source to probe and characterize the source electric potential. Accurate extraction of the source potential model parameters requires a detailed understanding of the krypton conversion electron spectrum. In this poster, we present recent measurements and analysis results from calibration campaigns using 83mKr, focusing on the determination of the KATRIN source electric potential and its impact on the experiment’s systematic uncertainties.
