Joint research project KATRIN: Measurement of the neutrino mass from the tritium beta decay, project 1: set up and commissioning (KATRIN)

Basic data for this project

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 a high luminous windowless gaseous tritium source in combination with 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 at Karlsruhe Institute of Technology, campus north (previously Reseach Center Karlsruhe). The Münster group has developed the 690m2 large electrode system of the KATRIN main spectrometer for background reduction and is constructing and commissioning 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.
