Investigations of background due to secondary electron emission in the KATRIN-experiment

Leiber, Benjamin

Abstract:
KATRIN will determine the effective mass of the electron anti-neutrino with a sensitivity of 200 meV (90% C.L.) by scanning the tritium-beta-spectrum close to the endpoint energy with unprecedented precision. The focus of this work lies on the detailed investigation of one of two main background sources of the experiment: the emission of secondary electrons from the large inner surface of the stainless steel vessel which are caused caused by cosmic ray muons and environmental radiation.
