Description

Here we present the current technical design of the SPHERE project’s new detector. The SPHERE project is aimed at primary cosmic ray studies in the 1-1000 PeV energy range using reflected Cherenkov light. The concept of a drone-mounted detector with a photosensitive camera based on silicon photomultipliers is discussed. The combination of the reflected CL registration method with specific data analysis approaches is a unique feature of this project. The developed earlier event-by-event data analysis approach allows to carry out primary particle mass reconstruction and PCR mass composition studies with high accuracy. This is achieved through careful analysis of each EAS CL lateral distribution function without building any kind of intermediate distributions of any “typical” characteristics.
