Search for EAS candidates with the TUS /Lomonosov orbital experiment: results of preliminary data reconstruction and analysis

The "Lomonosov" satellite, with the TUS instrument on board, was launched on April 28, 2016 on solar-synchronized orbit with altitude about 500 km. The main goal of the TUS space experiment is to search the Ultra High Energy Cosmic Rays (UHECR) at E >~70 EeV by measuring the fluorescence and Cherenkov radiation of extensive air showers (EAS) in the Earth's atmosphere. The TUS instrument's design and principles of operation are briefly presented. A multi-level algorithm for the search of EAS-like events was developed and applied to the TUS data set analysis. The preliminary results of the off-line reconstruction program for data analysis, search and study of candidates for the UHECR event are described and its parameters as statistical characteristics and arrival directions are presented.
