论文摘要
暗物质粒子探险器（DAMPE）是一种太空式高能宇宙射线和$γ$ - 雷检测器，自2015年12月17日发布以来，它可以顺利运行。二氧化碳（BGO）卡路里仪是用于能量测量和电子蛋白质蛋白质质子识别的DAMPE的关键子探测器之一。对于总能量沉积高于数十年的TEV的事件，在BGO晶体上耦合的PMT的读数将变得饱和，从而低估了能量测量值。基于详细的模拟，我们根据相邻BGO晶体测得的淋浴开发拓扑和能量开发了饱和效应的校正方法。使用模拟和轨道事件进行的验证表明，该方法可以很好地重建饱和BGO晶体中的能量沉积物。
The DArk Matter Particle Explorer (DAMPE) is a space-borne high energy cosmic-ray and $γ$-ray detector which operates smoothly since the launch on December 17, 2015. The bismuth germanium oxide (BGO) calorimeter is one of the key sub-detectors of DAMPE used for energy measurement and electron proton identification. For events with total energy deposit higher than decades of TeV, the readouts of PMTs coupled on the BGO crystals would become saturated, which results in an underestimation of the energy measurement. Based on detailed simulations, we develop a correction method for the saturation effect according to the shower development topologies and energies measured by neighbouring BGO crystals. The verification with simulated and on-orbit events shows that this method can well reconstruct the energy deposit in the saturated BGO crystal.
