论文摘要
使用MC预测与检测器和洞穴的CMS Fluka模拟,已经研究了CMS RPC系统中的预期辐射背景。分析中使用的MC几何形状非常准确地描述了当前的RPC系统,但仍未包括使用伪the的RPC升级区域的完整描述$ 1.9 <\ lvertη\ rvert <2.4 $。目前的结果将在最终的几何描述中进行更新。辐射背景已经根据预期的颗粒速率,吸收剂量和通量研究。已经研究了两个高光度LHC(HL-LHC)方案 - 收集了$ 3000 $和$ 4000 $ fb $^{ - 1} $之后。还考虑了安全系数为3的估计。
The expected radiation background in the CMS RPC system has been studied using the MC prediction with the CMS FLUKA simulation of the detector and the cavern. The MC geometry used in the analysis describes very accurately the present RPC system but still does not include the complete description of the RPC upgrade region with pseudorapidity $1.9 < \lvert η\rvert < 2.4$. Present results will be updated with the final geometry description, once it is available. The radiation background has been studied in terms of expected particle rates, absorbed dose and fluence. Two High Luminosity LHC (HL-LHC) scenarios have been investigated - after collecting $3000$ and $4000$ fb$^{-1}$. Estimations with safety factor of 3 have been considered, as well.
