Description

The TUS space experiment is aimed to study the energy spectrum and arrival direction of Ultra High Energy Cosmic Rays (UHECR) at E ⁓10^20 eV by measuring the fluorescence yield of EAS in the atmosphere. The "Lomonosov" satellite, with TUS, was launched at the April 16, 2016. Satellite now is in orbit and fully operational. The TUS collaboration design and produce a ground-based system of light sources for the in-flight calibration of the TUS detector. Two types of the possible UV light sources were selected for this purpose: LEDs and laser stations. Now laser station Simeiz-1873 can produce UV light and completed more than 10 experiments. But short time under satellite position, and time gaps in TUS operation make detecting of a event extremely hard.
