STUDY OF THE INTERACTION OF PARTICLES OF SPACE RADIATION BY THE HYBRID IONIZATION CALORIMETER METHOD

At present, in cosmic rays at energies above 1015 eV, a certain number of phenomena are observed mainly in the trunk (center) region of a wide air shower (EAS) that do not fit into the traditional concepts of the nuclear cascade process in the atmosphere. If we consider that the trunk region with a radius of up to 10 meters at a distance of 20–30 km from the point of the first interaction of a particle that produced an EAS, belongs to the pseudo-fastness region that is inaccessible on accelerators, then the study of the central part of EAS is a good addition to accelerator experiments. It is also possible that unusual particles can be present in the cosmic-ray flux at energies above 1015 eV, which are the primary cause of the observed anomalous phenomena in experiments with cosmic radiation and which, due to their properties, are not observed in accelerator experiments. The complex installation “ADRON-55” is located at an altitude of 3340 meters above sea level and is part of the unified system of registration of particles of cosmic radiation at the Tian-Shan high-altitude scientific station. The “ADRON-55” facility is aimed at solving a number of astrophysical and nuclear physics problems: the study of interactions of high-energy hadrons in the central part of EAS trunks, the search for sources of high-energy cosmic rays.
