Joint research project KATRIN: Measurement of the neutrino mass from tritium beta decay: Commissioning and start of data taking of the KATRIN experiment (KATRIN)

Basic data for this project

Type of project: Participation in federally funded joint project

Duration at the University of Münster: 01/07/2011 - 30/06/2014 | 2nd Funding period

Description

The KATRIN experiment will determine the neutrino mass with a sensitivity of 0.2eV/c2 from the precision measurement of the tritium beta spectrum near its endpoint. The KATRIN experiment uses ahigh luminous windowless gaseous tritium source in combinationwith an electrostatic retardation spectrometer of MAC-E-Filter type,which combines a very high energy resolution with a very large accepted solid angle.The experiment is being set up by a large interational collaboration atKarlsruhe Institute of Technology, campus north (previously Reseach Center Karlsruhe).The Münster group has developed and built the 690m2 large electrode system of the KATRIN main spectrometer for background reduction and is commissioning the system of the 248 electrode modules. Other Münster projects in KATRIN are the precision high voltage distribution and measurement, various calibration electron sources, the KATRIN data base, analyses and simulations.
