摘要:

这项工作是一个有条不紊的研究的另一种选择的混合方法,最初的目标是在TAIGA实验中的γ/强子分离。在本文中,这种技术进行区分不同质量群的宇宙射线的能量范围为200 TeV - 500 TeV。该研究基于TAIGA原型的模拟数据,包括分析IACT模拟中不同核产生的图像的几何形状以及使用定时阵列模拟重建的簇射堆芯参数。我们表明,混合方法可以有效地精确区分质量群的宇宙射线。

英文摘要:

This work is a methodical study of another option of the hybrid method originally aimed at gamma/hadron separation in the TAIGA experiment. In the present paper this technique was performed to distinguish between different mass groups of cosmic rays in the energy range 200 TeV - 500 TeV. The study was based on simulation data of TAIGA prototype and included analysis of geometrical form of images produced by different nuclei in the IACT simulation as well as shower core parameters reconstructed using timing array simulation. We show that the hybrid method can be sufficiently effective to precisely distinguish between mass groups of cosmic rays.
