The aim of the KArlsruhe TRItium Neutrino experiment is to improve the current neutrino mass sensitivity limit to 0.2 eV/c2 (90%C.L.). For that, the required proof of suitability of several components for a low pressure tritium atmosphere is furnished. In addition, an optical design for an e-gun is developed and the resulting electron rate is calculated. Also, a final Rear Wall with temporally stable and homogeneous work function is developed and characterized within the scope of this thesis.
