论文摘要
在LHC时代，探测器系统在苛刻的辐射环境中运行，颗粒通量很高。位置敏感的硅设备通常位于实验设置的最内向区域，必须应对高度不均匀的辐射场。在LHC运行II的结尾，硅跟踪器的通量达到10 $^{15} $ n $ _ {eq} $/cm $ $^2 $。初始仿真研究预测，HL-LHC的最大通量可能比LHC Run I和Run II中的一个数量级高两个数量级。在本文中，比较了在LHC Energies：Pythia 8.2和DPMJET 3上使用用于模拟质子 - 蛋白质碰撞的两个通用物理事件。使用这些模型获得的通力以及对LHC数据的最新调整，在位于质子 - 普罗顿碰撞点附近的检测器中也确定了。
At the LHC era, the detector systems are operating at the harsh hadronic environment with the unprecedentedly high particle flux. Position sensitive silicon devices are usually positioned at the innermost regions of the experimental setups and must cope with highly non-uniform radiation fields. At the end of LHC Run II, fluence in silicon trackers reached 10$^{15}$ n$_{eq}$/cm$^2$. Initial simulation studies predict that the maximal fluence for the HL-LHC may be up to two orders of magnitude higher than the one seen in LHC Run I and Run II. In this paper, two general-purpose physics events generators used for simulation of proton-proton collisions at LHC energies: Pythia 8.2 and DPMJET 3, are compared. Fluences obtained using these models, with the latest tuning to the LHC data, in detectors situated close to the point of proton-proton collisions are determined as well.
