One of the main directions of research activities is the
development of methods for deep underwater elementary particles
detection and construction of detectors using vast bulks of water of
natural reservoirs as target and working substances. At the Baikal
Neutrino Station a unique large telescope NT-200 is now being
constructed for deep underwater neutrino research with an effective
detection area 2-11 thousand square meters (for atmospheric muons) and
controlled water bulk of about 200 thousand cubic meters.
The construction of this many-purpose setup will allow one to search
for new elementary particles and rare processes and fulfill a large-scale
experimental research program in the field of high-energy cosmic ray physics.
