The major scientific goals of DArk Matter Particle Explorer (DAMPE) are to study cosmic-ray electrons (including positrons) and gamma rays from 5 GeV to 10 TeV and nuclei from Z = 1 to 26 up to 100 TeV. The deposited energy measured by the Bismuth Germanate Oxide (BGO) calorimeter of DAMPE is affected by fluorescence attenuation in BGO crystals that are 600 mm long. In this work, an in-orbit attenuation calibration method is reported, and energy correction of the sensitive detector unit of the BGO calorimeter is also presented.

基于 DAMPE 荧光衰减的能量校正

暗物质粒子探测器 (DAMPE) 的主要科学目标是研究 5 GeV 至 10 TeV 的宇宙射线电子（包括正电子）和伽马射线以及 Z = 1 至 26 至 100 TeV 的原子核。DAMPE 的锗酸铋 (BGO) 量热仪测量的沉积能量受 600 毫米长 BGO 晶体中荧光衰减的影响。在这项工作中，报告了一种在轨衰减校准方法，并介绍了 BGO 热量计敏感探测器单元的能量校正。
