Abstract A method is proposed to reconstruct the depth at which showers reach the maximum number of charged particles (X max charged ) using atmospheric Cherenkov telescopes. The dependence of the Cherenkov signal with telescope distance from shower core is explored and a region in which the measurement is possible is determined (150 to 200 m). A parametrization is presented to reconstruct X max charged . The resolution of the method is studied as a function of energy, for different primary particle types and for telescope fields of view ranging from 3.5∘ to 10∘. Good resolution ( ∼ 25 g/cm2) is achieved for most of the cases of primary particle type (gamma ray, proton and iron nuclei) and energy (10 TeV 40 g/cm2) is seen for energies below 30 TeV. The results presented here contribute to the understanding of the development of gamma-ray showers and suggest another possibility of using atmospheric Cherenkov telescopes to study cosmic rays in the TeV-PeV energy range.

使用切伦科夫灯测量大范围空气淋浴的最大淋浴深度

摘要 提出了一种使用大气切伦科夫望远镜重建淋浴达到最大带电粒子数（X max Charge ）时的深度的方法。探讨了切伦科夫信号与距淋浴核的望远镜距离的相关性，并确定了可以进行测量的区域（150 至 200 m）。提出了一个参数化来重建 X max Charged 。对于不同的初级粒子类型和范围从 3.5∘ 到 10∘ 的望远镜视场，该方法的分辨率被研究为能量的函数。对于大多数初级粒子类型（伽马射线、质子和铁核）和能量（10 TeV 40 g/cm2）而言，可以实现良好的分辨率（~ 25 g/cm2）低于 30 TeV 的能量。
