Deep Underwater Stationary Neutrino Telescopes on the Baikal Lake. 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. |

The Telescope Array is a large scale experiment located in Utah, USA. It is designed for registration of cosmic rays with energies greater than 1018 eV. The experiment consists of the array of 512 surface detector covering 700 km2 and three fluorescence telescope stations on a 30 km triangle. |

International project LHAASO - Large High Altitude Air Shower Observatory - is the next generation ground-based gamma-ray astronomy and cosmic ray experiment. It is situated in Sichuan province in (China) at altitude of 4410 m. Several arrays joined by LHAASO have record parameters and can measure all EAS components: Cherenkov light, muons, electrons and gammas. There were no hadronic detectors envisaged in the original project and INR RAS proposed to add the ENDA (Electron-Neutron Detector Array) consisting of 400 electron-neutron detectors (en-detectors elaborated in INR, recording electron and hadronic EAS components over whole array area) deployed on surface as a 5-m grid over 100 x 100 m2 total area. This could improve the LHAASO performances to measure mass composition and energy spectrum of cosmic rays in PeV region. The ENDA could serve as a giant hadronic calorimeter of 104m2, which could be expanded later unlimitedly. The proposal had been accepted. |
