A dedicated system for monitoring the tritium source in KATRIN — •Alan Poon — Karlsruhe Institute of Technology, KCETA, Karlsruhe, Germany — Lawrence Berkeley National Laboratory, Berkeley, California, USA

KATRIN is a next-generation tritium beta decay experiment with a neutrino mass sensitivity of 0.2 eV. The tritium source is confined in a windowless cylindrical containment, and the source's ``thickness'', or ``column density'' is one of the dominant systematic errors in the experiment. This column density has a direct impact on the transmission of electrons from the source to the spectrometer. A system consists of an electron gun for testing the electron transmission and a detector system for determining the electron flux in the tritium source is being developed. In this talk, this system to be installed in the rear of the tritium source will be described.
