The wide range front-end electronics for readout amplitude date of the ionization calorimeter

Abstract In this paper the set analog converters for the multi channel analog processor is presented. This processor is used in high-energy cosmic-ray experiments involving ionization calorimeter is sited near Alma-Ata at a height of 3340 m above sea level, at the Tien Shan. Also the system front-end electronics with dynamic range 500000 : 1, worked put specialty for research of halo at the ionization calorimeter is cited

Search for structures in the distribution of particles from the central area of wide atmospheric showers conducted on the Adron-55 installation

The ionization calorimeter “Adron-55”, located at an altitude of 3340 meters above sea level, is part of the unified registration system for the shower installation of the Tian-Shan high-mountain station. The “Hadron-55” installation is a 2-tier ionization calorimeter consisting of a shower system, a gamma block and a hadron block located under it with a vertical air gap of 2.2 meters. The calorimeter consists of 6 layers of ionization chambers with 144 chambers in each layer and a spatial resolution of the WAS structure equal to 11 cm. The total area of the calorimeter is 55 square meters with an absorber thickness of 1150 g / cm2. The calorimeter also contains helium counters for recording the neutron component. The central shower calorimeter system contains 30 scintillation detectors with an area of 400 m2 and 8 peripheral Sc-detectors at a distance of up to 100 m. The total area of the entire recording system is ~ 30000 m2. Over 4 years of operation, more than 120,000 events with energies above 1015 eV have been recorded. Currently, the processing and analysis of the data being obtained are performed

Modern status of the Tien-Shan cosmic ray station

We present a description of the new complex installation for the study of extensive air showers which was created at the Tien Shan mountain cosmic ray station, as well as the results of the first measurements made there in 2015–2016. We also present new results on high-energy radiation observed during a thunderstorm

High energy cosmic rays and thunderstorm connected radiations at the Tien Shan complex installation

We present a general description as well as a sample of illustrative experimental results of the Tien Shan high altitude detector complex which is aimed for fundamental and applied investigations in different fields of astroparticle, atmospheric, and environmental physics. The unique natural conditions of the Tien Shan Mountain Scientific Station where this complex resides, the presence of a modern equipment, and the use of multi-messenger integrated approach by detection of various radiation types open a new stage of research in cosmic ray physics and high-energy atmospheric phenomena
