Cross-check of KATRIN simulation and analysis tools — •Dominik Fuchs for the KATRIN collaboration — Max Planck Institute for Physics — Technical University of Munich
The Karlsruhe Tritium Neutrino (KATRIN) experiment is designed to determine the effective electron anti-neutrino mass with a sensitivity of 200 meV/c2 (90% C.L.) by the investigation of the kinematics of tritium beta decay in a direct and model independent way.
The modeling of the spectrum is based on theoretical calculations using Fermi theory combined with properties of the experimental setup. Those properties include e.g. scattering of electrons in the source as well as spectrometer and detector responses.
Due to the high complexity of the modeling and fitting of the experimental data, a validation of the analysis tools is essential. For this purpose a procedure has been developed which is mainly based on comparisons of independent sofware. This talk will present the basic philosophy of the KATRIN validation procedure and show the results of a first detailed comparison of two independent KATRIN analysis tools.
