New generation Cherenkov telescope array: HADAR and its performance introduction

Astrophysical very high energy (VHE) gamma-rays are believed to result almost exclusively from the interactions of populations of highly relativistic particles with ambient matter or photon fields. The study of these VHE photons therefore allows us to examine the processes of particle acceleration in the Universe, and the extreme environments in which they occur.To explore the origins and properties of gamma-rays, the High Altitude Detection of Astronomical Radiation (HADAR) experiment has been proposed to study these events. The refractive atmospheric Cherenkov telescope, a key component of HADAR, features a wide field of view (FOV) and exceptional sensitivity. It is designed to indirectly detect gamma-rays by capturing Cherenkov radiation produced by extensive air showers initiated by primary gamma-rays. This study concentrates on the design and performance parameters of the refractive atmospheric Cherenkov telescope array.

Abstract

Astrophysical very high energy (VHE) gamma-rays are believed to result almost exclusively from the interactions of populations of highly relativistic particles with ambient matter or photon fields. The study of these VHE photons therefore allows us to examine the processes of particle acceleration in the Universe, and the extreme environments in which they occur.To explore the origins and properties of gamma-rays, the High Altitude Detection of Astronomical Radiation (HADAR) experiment has been proposed to study these events. The refractive atmospheric Cherenkov telescope, a key component of HADAR, features a wide field of view (FOV) and exceptional sensitivity. It is designed to indirectly detect gamma-rays by capturing Cherenkov radiation produced by extensive air showers initiated by primary gamma-rays. This study concentrates on the design and performance parameters of the refractive atmospheric Cherenkov telescope array.
