Simulation of global beamline alignment of the KATRIN experiment — •Marco Deffert for the KATRIN collaboration — Hermann-von-Helmholtz-Platz 1, 76344 Eggenstein-Leopoldshafen

The KArlsruhe TRItium Neutrino (KATRIN) experiment aims to determine the effective mass of the electron anti-neutrino with a sensitivity of 200 meV/c² (90 % C.L.) by investigating the kinematics of tritium β-decay. For this purpose it uses a high luminosity windowless gaseous tritium source (A=10¹¹ Bq) combined with a high resolution electrostatic spectrometer (Δ E =0.93 eV at 18.6 keV). In fall 2016 First Light measurements were performed with the full KATRIN beamline when electrons were guided magnetically through the 70-m long setup for the first time.

In order to simulate the electron transport and interactions in KATRIN the KASSIOPEIA particle tracking framework has been developed. This talk will focus on the implementation of the full KATRIN beamline into KASSIOPEIA and first results on simulations of the electron transport with regards to the First Light measurements.
