In the Karlsruhe Tritium Neutrino Experiment (KATRIN) the mass of the electron neutrino is intended to be measured directly by precision energy spectroscopy of the tritium β-decay electrons in its endpoint region. To achive the target sensitivity of 0.2 eV/c2, a reduction of background electrons, assumed to be caused by Rydberg atoms and autoionizing states, is needed. An active transverse energy filter (aTEF, Eur. Phys. J. C 82, 922 (2022)) distinguishes electrons due to their angle to a magnetic field line. It preferentially detects signal electrons with a broad angular distribution rather than background electrons with a small angular distribution. This poster presents insight in the testing procedures and characterization of aTEF-prototypes in dedicated test environments.
