The Muon Upgrade Phase II of the Compact Muon Solenoid (CMS) aims to guarantee the optimal conditions of the present system and extend the $\eta$ coverage to ensure a reliable system for the High Luminosity Large Hadron Collider (HL-LHC) period. The Resistive Plate Chambers (RPCs) system will upgrade the off-detector electronics (called link system) of the chambers currently installed chambers and place improved RPCs (iRPCs) to cover the high pseudo$-$rapidity region, a challenging region for muon reconstruction in terms of background and momentum resolution. In order to find the best option for the iRPCs, an R\&D program for new detectors was performed and real size prototypes have been tested in the Gamma Irradiation Facility (GIF++) at CERN. The results indicated that the technology suitable for the high background conditions is based on High Pressure Laminate (HPL) double-gap RPC. The RPC Upgrade Phase II program is planned to be ready after the Long Shutdown 3 (LS3).

CMS二期RPC升级项目
紧凑型μ子螺线管（CMS）的μ子升级第二阶段旨在保证现有系统的最佳条件并扩展$\eta$覆盖范围，以确保高亮度大型强子对撞机（HL-LHC）时期的可靠系统。电阻板室 (RPC) 系统将升级当前安装的室的探测器外电子设备（称为链接系统），并放置改进的 RPC (iRPC) 以覆盖高伪 $-$ 快速区域，这是一个具有挑战性的介子重建区域在背景和动量分辨率方面。为了找到 iRPC 的最佳选择，我们执行了新探测器的研发计划，并在欧洲核子研究中心的伽玛辐照设施 (GIF++) 中测试了真实尺寸的原型。结果表明，适用于高背景条件的技术是基于高压层压 (HPL) 双间隙 RPC。RPC 升级第二阶段计划计划在长时间停机 3 (LS3) 后准备就绪。
