A prototype string for the future km
3-scale Baikal neutrino telescope has been deployed in April, 2008, and is fully integrated into the NT200+ telescope. All basic string elements–optical modules ...(with 12″/13″ hemispherical photomultipliers), 200
MHz FADC readout and calibration system–have been redesigned following experience with NT200+. First results of in-situ operation of this prototype string are presented.

A km-scale (Gigaton Volume) Neutrino telescope in Lake Baikal is planned, the R&D phase has started in 2006. We give the basic layout of this Baikal km3-detector, which will be made of building blocks similar to

We present the first neutrino induced events observed with a deep underwater neutrino telescope. Data from 70 days effective life time of the BAIKAL prototype telescope NT-96 have been analyzed with ...two different methods. With the standard track reconstruction method, 9 clear upward muon candidates have been identified, in good agreement with 8.7 events expected from Monte Carlo calculations for atmospheric neutrinos. The second analysis is tailored to muons coming from close to the opposite zenith. It yields 4 events, compared to 3.5 from Monte Carlo expectations. From this we derive a 90% upper flux limit of 1.1 · 10

An optical detector and an electronic system have been developed for studying the shape of Cherenkov light pulses from extensive air showers in the TUNKA experiment. Results of measurements on the ...described experimental setup are presented.
