KATRIN: Status Update

ORAL

Abstract

The KArlsruhe TRItium Neutrino (KATRIN) experiment has produced the first sub-eV sensitivity direct neutrino-mass scale measurement from tritium beta decay, and aims to improve its sensitivity to 0.2 eV (90% C.L.). In order to reach this sensitivity, a large number of events near the kinematic endpoint of the tritium beta decay need to be recorded to reduce the statistical uncertainty. Systematic effects affecting the measurement also need to be accurately known and well understood. In this presentation we will report on progress towards the next neutrino-mass result with regards to statistical and systematic uncertainties.
