Collaborating countries | Russia, Germany |
Number of authors | 55 |
Number of PhD students | 5 |
Location/Infrastructure | Lake Baikal, Siberia; Research Base operated by INR. |
Funding agencies | Russian Academy of Sciences, Ministry of Education and Technology of Russia, Russian Fund of Basic Research, DESY, German Ministry of Science |
Scientific goals | High energy neutrino astronomy, dark matter search, exotic particle search, limnology |
Design | NT200: 192 optical modules at 8 strings, height 72 m, diameter 42 m, depth ~ 1.1 km. NT200+: NT200 plus 3 outer strings, height 210 m, diameter 200 m, geometric volume 5 Mton. |
Present status (R&D, construction, data taking, closed) | NT200 completed in 1998, data taken from 1998-2005. NT200+ upgrade completed in April 2005, data taking. |
Most relevant results | Limits on fluxes of - diffuse all-flavour neutrinos: 8.1* 10-7 GeV cm-2 s-1 sr-1 - muons from WIMP annihilation/Earth: 2* 103 km-2 yr-1 - relativistic magnetic monopoles: 5* 10-17 cm-2 s-1 sr-1 |
Perspective: - total cost, status of funding - merging with other projects - close R&D relations to other projects - coming relevant reviews - branch points | NT200+ is also a prototype for a kilometer size telescope at Lake Baikal: - 2006-2009: R&D (funded) - 2009/2010: start of construction A Baikal gigaton detector is part of the long-term basic research strategy in Russia. |
Which relevant results are expected, and when | Sensitivity based on 3 years of NT200+ data: - diffuse all-flavor neutrino flux: 2* 10-7 GeV cm-2 s-1 sr-1 - muons from WIMP annihilation/Earth 4* 102 km-2 yr-1 - relativistic magnetic monopoles: 2* 10-17 cm-2 s-1 sr-1. - limit on the neutrino flux from Galactic Center |
