LHAASO-KM2A阵列探测器模拟软件设计

摘要

The design of detector simulation of KM2A is introduced. In this design,the Geant4 is used to construct the KM2A array with more than six thousand detectors, and then to simulate the detector response to the secondary particles of showers. The simulation procedure is optimized to significantly reduce the memory consuming to avoid memory overflow. Some simplifications are used to significantly speed up the simulation to satisfy the practical requirement.%介绍KM2A模拟软件的设计.该设计基于Geant4建立由6000多个探测器组成的LHAASO-KM2A阵列,模拟各探测器对广延大气簇射中次级粒子响应,并通过优化模拟流程大幅降低软件运行时的内存需求避免内存溢出,通过简化部分模拟大幅提高软件运行速度,使软件满足实际需求.
