An experimental setup consisting of 12 layers of glass Resistive Plate Chambers (RPCs) of size 2m$\times$2m has been built at IICHEP-Madurai to study the long term performance and stability of RPCs produced on large scale in Industry. In this study, the data obtained by this setup was analysed to find out the events where more than one trajectories of charged particles are detected within a single trigger window. The results obtained from observation was then compared with different hadronic models of CORSIKA prediction.

在 IICHEP-Madurai 使用 2 m × 2 m 电阻板室堆栈研究宇宙射线事件的粒子多样性

在 IICHEP-Madurai 建造了一个由 12 层玻璃电阻板室 (RPC) 组成的实验装置，尺寸为 200 万美元\times $200 万美元，用于研究工业上大规模生产的 RPC 的长期性能和稳定性。在这项研究中，分析了通过此设置获得的数据，以找出在单个触发窗口内检测到多个带电粒子轨迹的事件。然后将观察获得的结果与 CORSIKA 预测的不同强子模型进行比较。
