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 < |η| < 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.

CMS RPC 背景 — 研究和测量
CMS RPC 系统中的预期辐射背景已使用 MC 预测与探测器和洞穴的 CMS FLUKA 模拟进行了研究。分析中使用的 MC 几何非常准确地描述了当前的 RPC 系统，但仍然不包括伪快速度为 1.9 < |η| 的 RPC 升级区域的完整描述。< 2.4。一旦可用，当前的结果将使用最终的几何描述进行更新。已经根据预期粒子率、吸收剂量和注量对辐射背景进行了研究。在收集 3000 和 4000 fb -1之后，研究了两种高亮度 LHC (HL-LHC) 情景。还考虑了安全系数为 3 的估计值。
