Abstract
  • Experiments in recent years have shown neutrinos have non-zero rest mass. The Karlsruhe Tritium Neutrino experiment (KATRIN) will directly probe the electron anti-neutrino mass using tritium beta decay. KATRIN's main spectrometer aims to provide a \\SI{0.2}{eV} sensitivity to the neutrino mass, an order of magnitude improvement over the previous generation of experiments. During KATRIN's most recent commissioning phase, a mono-energetic electron source was used to probe transmission properties and study associated potential systematic errors in the main spectrometer. Charge accumulation from this source is identified as a potential source for systematic error and the impact on the neutrino mass measurement is estimated.
