Scientists of the laboratory take part in collaboration with participants of the MAGIC project. The project envisage the contruction of a Cherenkov telescope with the aid of which gamma-rays of energy below 100 Gev may be detected. The Crimean group is going to construct and tune the light receiver of LIDAR which will work jointly with main detector to estimate the distribution of light scattering in the atmosphere for correcting the light distribution of images of Cherenkov flashes. The work is in the beginning. Now we know the way for evaluation of the height distribution of the scattering and have design of the light receiver of the LIDAR.
