Abstract

The study describes the experimental complex of the station located in the Tien Shan mountains at an elevation of 3340 m above sea level. The complex consists of detectors of different types scattered across the station area, such as scintillation particles detectors, Cherenkov detectors, radio emission detectors for the measurement of the electron component of extensive air showers (EAS) created by the (1–1000) PeV cosmic ray particles, an ionization calorimeter and neutron detectors for the study of the nuclear-active component of EAS cores, and the underground particle detectors for the detection of cosmic ray muons. The data acquisition system allows the simultaneous recording of parameters from various stand-alone detectors registering an EAS, and storage of the acquired data in the database. As an illustration of research capability, the results of the EAS study are presented here which were obtained during the last few years at the different experimental set-ups constituting the Tien Shan complex.

Highlights

  • In the 1960s an experimental research complex of the Tien Shan mountain cosmic ray station was developed by the Institute of Physics and Technology of the Ministry of Education and Science of the Republic of Kazakhstan and of the P

Summary

Introduction

Investigation of the processes of high-energy particle interaction measuring extensive air showers (EAS) which are the large cascades consisting of (105 –108 ) secondary particles, mostly electrons, created by the (1–1000) PeV cosmic rays in the atmosphere [2]. Study of the large-scale distribution of cosmic ray primaries’ directions over the celestial sphere and the search for possible sources of high energy cosmic rays, in dependence on their energy, using the anisotropy effects of this distribution [5,6]. Study of the large-scale distribution of cosmic ray primaries’ directions over the ce of 11 lestial sphere and the search for possible sources of high energy cosmic rays, in dependence on their energy, using the anisotropy effects of this distribution [5,6].
