The Lake Baikal neutrino experiment: selected results
We review the present status of the lake Baikal Neutrino Experiment and
present selected physical results gained with the consequetive stages of the
stepwise increasing detector: from NT-36 to NT-96. Results cover atmospheric
muons, neutrino events, very high energy neutrinos, search for neutrino events
from WIMP annihilation, search for magnetic monopoles and environmental
studies. We also describe an air Cherenkov array developed for the study of
angular resolution of NT-200.Comment: 25 pages, 12 figures. To appear in the Procrrdings of International

BAIKAL experiment: status report
We review the present status of the Baikal Neutrino Project and present the
results obtained with the deep underwater neutrino telescope NT-200.Comment: 4 pages, 3 figures. Presented at TAUP 2001 (7th international

The ANTARES Optical Module
The ANTARES collaboration is building a deep sea neutrino telescope in the
Mediterranean Sea. This detector will cover a sensitive area of typically 0.1
km-squared and will be equipped with about 1000 optical modules. Each of these
optical modules consists of a large area photomultiplier and its associated
electronics housed in a pressure resistant glass sphere. The design of the
ANTARES optical module, which is a key element of the detector, has been
finalized following extensive R & D studies and is reviewed here in detail.Comment: 26 pages, 15 figures, to be published in NI
Neutrino Detectors Under Water and Ice
Underwater/ice neutrino telescopes are multi-purpose detectors covering astrophysical, particle physics and environmental aspects. Among them, the detection of the feeble fluxes of astrophysical neutrinos which should accompany the production of high energy cosmic rays is the clear primary goal. Since these neutrinos can escape much denser celestial bodies than light, they can trace processes hidden to traditional astronomy. Different to gamma rays, neutrinos provide incontrovertible evidence for hadronic acceleration. On the other hand, their extremely low interaction cross section makes their detection extraordinarily difficult
The BAIKAL Neutrino Telescope: From NT200 to NT200+.
We review the status of the Baikal Neutrino Telescope, which has recently been upgraded to the 5 Mton detector NT200+. We present results on searches for upward going atmospheric neutrinos and relativistic magnetic monopoles, obtained from 1998-2002 with the predecessor detector NT200. A search for very high energy neutrinos yields an upper limit on the extraterrestrial diffuse neutrino flux for 20 TeV < E < 50 PeV. We describe the strategy of upgrading NT200 to NT200+ and creating a detector on the Gigaton (km3) scale at lake Baikal. R&D activities on that next stage detector have been started
The prototype string for the km3-scale Baikal neutrino telescope
A prototype string for the future km3-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), 200MHz FADC readout and calibration system - have been
redesigned following experience with NT200+. First results of in-situ operation
of this prototype string are presented.Comment: 8 pages, 15 figures; presented at VLVNT08 (Very Large Volume Neutrino
Telescope) Workshop, Toulon, France, April, 2008; to appear in NIM-
