Another look at KATRIN’s response function for isotropic and mono-energetic sources* — •Lukas Voß for the KATRIN collaboration — Bergische Universität Wuppertal
The KArlsruhe TRItium Neutrino (KATRIN) experiment aims to measure the effective electron neutrino mass in a model-independent way with a sensitivity of 200 meV/c2 (90 % C.L.).
Electrons are emitted isotropically in the Windowless Gaseous Tritium Source (WGTS) and guided by magnetic fields through the transport section and the two spectrometers. They are detected when they reach the focal plane detector (FPD). While the electrons travel towards the detector, their energy and angle to the guiding field are being influenced by elastic and inelastic scattering.
With help of KATRIN’s software package KASSIOPEIA the response function of the experiment is simulated. The response function is governed by the energy resolution and includes energy losses by elastic and inelastic scattering. Thereby, the expected spectral shape for isotropically emitted electrons, and electrons originating from an electron-gun at varying tritium cross-sections are investigated as well as the feasibility of full MC simulation of the response-function in KATRIN.
The results of the simulation are discussed in this talk.
