论文摘要
提出了由于CMS检测器的强子端盖（HE）卡路里量表中使用的塑料闪烁瓷砖的辐射损伤引起的信号输出的降低。将瓷砖暴露于质子 - 蛋白质（PP）碰撞的颗粒，其质量中心能量为13 tev，对应于50 fb $^{ - 1} $的递送发光度。这些测量基于使用硅光电培养基仪器的HE的读出通道，并使用来自多个来源的数据得出：激光校准系统，可移动的放射性源，以及在PP碰撞中产生的HADRON和MUON。还讨论了使用$^{60} $ CO来源的几个辐照活动的结果。损害是作为剂量率的函数所呈现的。在这些测量范围内，对于固定剂量，损害随剂量率降低而增加。
Measurements are presented of the reduction of signal output due to radiation damage for plastic scintillator tiles used in the hadron endcap (HE) calorimeter of the CMS detector. The tiles were exposed to particles produced in proton-proton (pp) collisions at the CERN LHC with a center-of-mass energy of 13 TeV, corresponding to a delivered luminosity of 50 fb$^{-1}$. The measurements are based on readout channels of the HE that were instrumented with silicon photomultipliers, and are derived using data from several sources: a laser calibration system, a movable radioactive source, as well as hadrons and muons produced in pp collisions. Results from several irradiation campaigns using $^{60}$Co sources are also discussed. The damage is presented as a function of dose rate. Within the range of these measurements, for a fixed dose the damage increases with decreasing dose rate.
