Description
The KArlsruhe TRItium Neutrino experiment (KATRIN) is a next generation tritium beta-decay experiment, which aims to determine the neutrino mass with an estimated sensitivity of $0.2$ eV/c$^2$ (90% C.L.).
One of the main sources of systematics in KATRIN is the scattering of beta-electrons on the source gas and its impact on the shape of the measured spectrum. To improve the understanding of the scattering cross-section and for additional systematics and monitoring tasks, the KATRIN beam line is equipped with a mono-energetic and angular selective electron source. This e-gun can reach electron energies of $32 \, keV$, energy widths better than $200 \, meV$ and rates of $100 \, kcps$.
The poster will give details on working principle, technical realization, commissioning measurements and future systematics studies and regular monitoring tasks.
