Registration of Cherenkov radiation flashes with the using of optical system of big solar furnace

The possibilities of using optical system of big solar furnace as a part of cosmic rays detection system is shown. The results of registration of Cherenkov radiation flashes from extensive air showers by the use of concentrating collector of solar furnace are presented. It was shown that solar concentrator with photoregistration system can be used in astrophysical researches as search and study high energy gamma-sources and optical bursts.
