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

用无人机载探测器研究 1-100 PeV 能量范围内初级宇宙射线的能谱和化学成分

一个新项目的开发实施了一种相对较新的初级宇宙射线研究方法——记录从雪面反射的大量空气淋浴的光学瓦维洛夫-切伦科夫辐射（切伦科夫光）。该项目的目的是通过探测反射的广泛空气淋浴的切伦科夫光来研究 1-100 PeV 能量范围内的宇宙射线质量组成。计划使用硅光电倍增管作为探测器的主要光敏元件，并计划使用无人机将测量设备抬升到积雪覆盖的地面上。
