The Karlsruhe Tritium Neutrino (KATRIN) experiment will provide a measurement of the effective electron-neutrino mass, $m(\nu_e)$, based on a precision measurement of the tritium beta decay spectrum near its endpoint. The effective mass is an average of the neutrino mass eigenstates $m_i$ weighted by the flavor-mass mixing parameters $U_{ei}$ according to the relation $m^2(\nu_e)=\sum_{i=1}^3...
