摘要:

结果表明,只要知道簇射最大值的垂直深度和地面探测器的总信号,就可以对μ子簇射含量进行高精度的估计。该估计几乎不依赖于初级能量和粒子类型以及天顶角。对QGSJET II/Fluka相互作用模式的21500个簇射进行了研究,这些簇射由能量范围$\log10(E)$ [eV]=18.5- 20的谱$E^{-1}$产生,并且在天顶角间隔$θ=0^\circ-65^\circ$的$\cos^2θ$中均匀分布。

英文摘要:

It is shown, that highly accurate estimation of muon shower content can be performed on the basis of knowledge of only vertical depth of shower maximum and total signal in ground detector. The estimate is almost independent on primary energy and particle type and on zenith angle. The study is performed for 21500 showers, generated with CORSIKA~6.204 from spectrum $E^{-1}$ in the energy range $\log10(E)$ [eV]=18.5--20 and uniformly in $\cos^2θ$ in zenith angle interval $θ=0^\circ-65^\circ$ for QGSJET II/Fluka interaction models.
