The progress in the construction and operation of the Baikal Gigaton Volume Detector in Lake Baikal is reported. The detector is designed for search for high energy neutrinos whose sources are not yet reliably identified. It currently includes over 3500 optical modules arranged on 98 strings, providing an effective volume of 0.6 km3 for cascades with energy above 1 PeV. We review the...
A brief history and the main results of the study of cosmic rays and high-energy gamma radiation using the Cherenkov EAS installations located in the Tunka Valley 50 km from the southwestern tip of Lake Baikal are presented. Since 1993, the important results have been got about the energy spectrum and mass composition of cosmic rays in the energy range of 1 – 1000 PeV with the Tunka-4,...
When we speak on Space Weather we are commonly meaning the radiation and electro magnetic conditions in the near Earth space. Cosmic ray variations define directly a radiation situation. And they are also related to the variations of electromagnetic conditions in the interplanetary space and Earth’s magnetosphere. This makes cosmic ray variations one of the important resources for validating...
Interest to study neutrons produced in Extensive Air Showers (EAS) is rising last years. Recent publications on this subject are overviewed and estimated. Advantages of the method to study hadronic component being the main EAS component, as well as perspectives of the method are shown.
