Muon Telescope Based on Scintillation Counters

A complex of four modern scintillation cosmic ray muon telescopes, which are part of the cosmic ray spectrograph after A.I. Kuzmin in Yakutsk, is described. Cosmic-ray detectors of this type are placed on the surface of the Earth, as well as in horizontal cuts that were specially dug in permafrost soils of a mine at depths of 7, 20, and 40 m of the water equivalent, and complement the previously created muon telescopes based on SGM-14 gas-discharge counters. New muon telescopes based on SC-301 scintillation counters have a significantly larger area and accuracy of registering muons of atmospheric origin and allow detection of charged particles from 13 different directions. We also report on a system for recording and transmitting data to a database server located at a distance from the Yakutsk cosmic ray station that operates under the control of the PostgreSQL10 system in real time.
