Abstract

The thunderstorm events observed by GRAPES-3 muon telescope can be studied with aid of Monte Carlo simulations. One such event observed on 1 December 2014 was analysed and its electrical properties of thundercloud were derived using muon imaging. This recent result showed production of Giga-Volt potential in thunderclouds, possibly responsible for production of 100 MeV $\gamma$-rays in terrestrial $\gamma$-ray flashes. However, these properties derived from simulations rely on choice of low and high energy hadronic interaction models used in CORSIKA. So, the derived properties are model dependent which makes this study very important. The comparison of various combinations using low and high energy hadronic models and its impact on electric potential estimation will be discussed in this work.

强子相互作用模式在GRAPES-3大气电场模拟中的依赖性。

葡萄-3 μ子望远镜观测到的雷暴事件可以借助蒙特卡罗模拟进行研究。对2014年12月1日观测到的一个这样的事件进行了分析，并利用μ子成像推导了其雷雨云的电学特性。最近的结果显示，雷雨云产生了千兆伏特的电势，这可能是在地面伽马射线闪光中产生100兆电子伏特伽马射线的原因。然而，从模拟中得出的这些性质依赖于CORSIKA中使用的低能和高能强子相互作用模型的选择。因此，导出的性质是模型依赖的，这使得本研究非常重要。本文将讨论低能和高能强子模型的各种组合的比较及其对电势估计的影响。
