Monitoring KATRIN source properties with the Forward Beam Monitor
The KArlsruhe TRItium Neutrino (KATRIN) experiment aims to measure the effective electron antineutrino mass in a model-indepedent way with a sensitivity of 200 meV/cē (90 % C.L.). In order to extract the neutrino mass the Windowless Gaseous Tritium Source (WGTS) properties need to be known to a high precision. For this reason several monitoring systems are installed. One of them is the Forward Beam Monitor (FBM). This system comprises of a complex mechanical setup capable of inserting a detector board into the KATRIN beamline at the end of the transport section. This talk will give an introduction to the KATRIN experiment, describe the technical properties of the FBM setup and present Monte-Carlo based simulations of the expected differential electron spectra for varied source configurations.
