论文摘要
CERN的LHCB（大型强子对撞机美女）的实验旨在实现比最初通过两个重大升级计划的最初计划的明显更高的发光度：在长时间关闭2（LS2）（LS2）和升级II期间进行的升级I预见了LS4。相对于设计值的瞬时和集成光度的增加需要重新评估LHC磁铁，低温和电子设备的辐射暴露，该设备位于LHCB周围的插入区域8（IR8）中。蒙特卡洛模拟是一种强大的工具，可以理解和预测粒子阵雨与加速器元素之间的相互作用，尤其是在未来情况下。为此，他们通过与可用测量的比较进行验证是相关的一步。通过Fluka代码实现了包括LHCB检测器在内的详细IR8模型。这项研究的目的是评估由于质子 - 普罗顿碰撞而引起的辐射水平，并基准对2018年进行的针对光束损耗监测仪（BLM）测量值的预测剂量值。最后，我们对即将到来的LHC运行（运行3）进行评论，以LHCB中的第一个亮度跳跃为特征。
The LHCb (Large Hadron Collider beauty) experiment at CERN aims at achieving a significantly higher luminosity than originally planned by means of two major upgrades: the Upgrade I that took place during the Long Shutdown 2 (LS2) and the Upgrade II foreseen for LS4. Such an increase in instantaneous and integrated luminosity with respect to the design values requires to reassess the radiation exposure of LHC magnets, cryogenics and electronic equipment placed in the Insertion Region 8 (IR8) around LHCb. Monte Carlo simulations are a powerful tool to understand and predict the interaction between particle showers and accelerator elements, especially in case of future scenarios. For this purpose, their validation through the comparison with available measurements is a relevant step. A detailed IR8 model, including the LHCb detector, has been implemented with the FLUKA code. The objective of this study is to evaluate radiation levels due to proton-proton collisions and benchmark the predicted dose values against Beam Loss Monitor (BLM) measurements performed in 2018. Finally, we comment on the upcoming LHC run (Run 3), featuring a first luminosity jump in LHCb.
