A hot cathode electron gun to test and characterize silicon drift detector arrays for the KATRIN experiment — •Korbinian Urban for the KATRIN collaboration — Technical University Munich, James-Franck-Straße 1, 85748 Garching bei München

The KATRIN (Karlsruhe Tritium Neutrino) experiment investigates the kinematic endpoint of the tritium beta-decay spectrum to determine the effective mass of the electron anti-neutrino. Its unprecedented tritium source luminosity and spectroscopic quality make it a unique instrument to also search for physics beyond the standard model such as sterile neutrinos. For these searches a new silicon drift detector array is being developed to replace the current silicon detector in KATRIN. Key features of the new detector are the high rate capability and good energy resolution for electrons. This talk presents a setup where these properties of the new detector modules can be tested with electrons of up to 20 keV kinetic energy from a hot cathode electron gun.
