Abstract :
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 . The TUS detector will measure the fluorescence and Cherenkov light radiated by Extensive Air Shower of the UHECR using the optical system that comprises a Fresnel mirror-concentrator of seven modules with a total area of ~ 2 m 2 . The production process of the Fresnel mirror and the method and results of measurement of its optical parameters are presented.
