EXPERIMENT KATRIN
Name of experiment/device KATRIN (Karlsruhe Tritium Neutrino) Experiment
Present Spokesperson
(location, email) 		G. Drexlin, Univ.+FZ Karlsruhe, drexlin@ik.fzk.de, C. Weinheimer, U M?nster, weinheimer@uni-muenster.de
Collaborating Institutions FZ+Univ. Karlsruhe, U Mainz, U Bonn, FH Fulda, INR Troitsk, UW Washington, UW Swansea, INP Rez/Prag
Collaborating countriesGermany, USA, UK, Russian Federation, Czech Republic
Number of authors 105
Number of PhD students 12
Location/Infrastructure FZ Karlsruhe
Funding agencies BMBF, HGF, PPARC, DOE, Russ.+Czech Academy
Scientific goals Measurement of neutrino mass with sensitivity 0.2eV
Design Windowless T2 source + Electrostatic retarding spectrometer + solid state detector
Present status (R&D, construction, data taking, closed) Major construction works have started, major order have been placed, test experiments are running, electro-magnetic of pre-sprectrometer on-going
Most relevant results Ultra high vacuum test concept confirmed
Perspective:
- total cost, status of funding
- merging with other projects
- close R&D relations to other
projects
- coming relevant reviews
- branch points 		Experiment approved by HGF, DOE funding still pending, worldwide unique experiment, close R&D work on tritium processing with fusion community via tritium laboratory Karlsruhe, HGF evalution finshed with positive feedback
Which relevant results are expected, and when Start of measurements end of 2008, then 5 years of measurements, final results in 2013
