Status of the KATRIN spectrometer and detector section — •Nancy Wandkowsky for the KATRIN collaboration — Karlsruhe Institute of Technology (KIT), Institute for Nuclear Physics (IKP)
The aim of the KArlsruhe TRItium Neutrino experiment is a model-independent determination of the effective mass of the electron antineutrino by a precise measurement of the Tritium β-spectrum with a sensitivity of 200 meV/c2. KATRIN utilizes a windowless gaseous tritium source, a differential and a cryogenic pumping section, a system of two electrostatic spectrometers, which are based on the MAC-E filter technique, and a multi-pixel silicon semiconductor detector. The experiment is currently being constructed at the Karlsruhe Institute of Technology.
In summer 2013, the combined Spectrometer and Detector System (SDS) has been successfully commissioned. The electron transmission and background characteristics of the spectrometer have been determined experimentally and have been verified by simulations.
This talk summarizes the current status of the KATRIN experiment, focusing on the results of the SDS commissioning phase.
Supported by the BMBF under grant no. 05A11VK3 and the Helmholtz Association.
