SEARCH AND STUDY OF EXTENSIVE AIR SHOWER EVENTS WITH THE TUS SPACE EXPERIMENT

Abstract

The TUS experiment is aimed to study the energy spectrum and arrival direction of Ultra High Energy Cosmic Rays at E ~ 100 EeV from the space orbit by measuring the fluorescence yield of the Extensive Atmospheric Shower in the atmosphere. It is the first orbital telescope designed for such measurements and is taking data since May 19, 2016. The TUS apparatus structure, methods of UHECR on-line selection and off-line data analysis are described. A few UHECR EAS candidates have been found. Preliminary results of their studying are presented.
