Abstract

The state-of-the-art Yakutsk cosmic ray spectrograph consists of the 24-NM-64 neutron monitor, four muon telescopes of the same type, and SGM-14 gas-discharge counters that detect particles coming from five directions and are installed at levels of 0, 7, 20, and 40 meters of water equivalent. A new complex of four muon telescopes of the same type based on SC-301 scintillation counters that record particles from 13 destinations has now been added to the spectrograph. Acceptance vectors that consider the geometry, geographical position, and energy spectra of the observed cosmic ray variations have been developed for these instruments. Analysis of the data from the new scintillation detectors shows that the count rate is as expected in all directions. The parameters of the acceptance characteristics of the new scintillation telescopes and current detection data are available on the Institute’s website at http://www.ysn.ru/smt.
