Investigation of the energy spectrum and chemical composition of primary cosmic rays in 1-100 PeV energy range with a UAV-borne detector

A new project is developed with the implementation of a relatively new method of studying primary cosmic rays - the detection of reflected from the snow surface optical Vavilov-Cherenkov radiation from extensive air showers. The aim of the new project is to study the cosmic ray mass composition in the energy range of 1-100 PeV. Silicon photomultipliers are planned to be used as the main photosensitive element of the detector and an unmanned aerial vehicle is going to be used to lift the measuring equipment over the snow surface.
