Baksan Neutrino Observatory Baksan Neutrino Observatory

Baksan Neutrino Observatory

is situated in the North Caucasus in the area of the Baksan river at a height of 1700 m above the sea level.

The underground setups are located under the mount Andyrchy (3922 m) at different distances from the entrance of the adit which is 4000 m in length.

It comprises

• the Baksan Underground Scintillation Telescope (BUST) with a volume of 3000 cub.m. at a depth of more than 800 meters of water equivalent (m.w.e);
• the highland setup Andyrchy for detecting wide atmospheric showers which is located above BUST and covers about 5*104 sq.m;
• the ground-based facility Carpet comprising a Large Muon Detector, Scintillation Telescope and Neutron Monitor for studying a hard component of cosmic rays and wide atmospheric showers;
• the Gallium-Germanium Neutrino Telescope with a 50 ton target of metallic gallium and a laboratory for extraction of germanium atoms located at a depth of 4700 m.w.e in the mountain rock;
• low-background laboratories at the depths of 660, 1000 and 4900 m.w.e.

The Observatory is a shared research center for various experiments in the field of fundamental and applied physics.

The underground telescopes are incorporated into the world network observing the processes in space.

Research Areas:

• studies of the internal structure and evolution of the Sun, stars, Galaxy nucleus and other objects of the Universe by detecting their neutrino emission;
• studies of neutrino properties with artificial neutrino sources;
• a search for new particles and super-rare processes predicted by various modern theoretical models at a sensitivity level inaccessible to other methods;
• investigation of high-energy cosmic rays, gamma-astronomy, a search for gravitational waves;
• studies of the influence of cosmic factors on the processes in the atmosphere and on the surface of the Earth.
