本文介绍了面向HL-LHC ATLAS MDT升级的二期CSM高速读出模块的设计与生产级验证，支持双路10.24 Gbps光学上行链路，并已投入生产。
AI 中文摘要
大型强子对撞机高亮度升级（HL-LHC）对ATLAS缪子谱仪提出了更高要求，特别是在数据吞吐量、时间分配和系统可靠性方面。二期腔室服务模块（CSM）是升级后的监视漂移管（MDT）触发和读出系统的关键组件，为前端电子学与后端系统提供高速接口。本文描述了二期CSM的设计、实现及其验证。结果表明，CSM支持两条独立的光学上行链路，每条链路工作在线速率10.24 Gbps，并在预期运行环境中提供时钟分配和慢控制。本文还介绍了与小直径MDT（sMDT）腔室的集成以及与原型L0MDT触发系统的测试。CSM板现已投入生产，将在即将到来的LHC长期停机期间用于安装和集成。
英文摘要
The High-Luminosity upgrade of the Large Hadron Collider (HL-LHC) introduces increased demands on the ATLAS Muon Spectrometer, particularly in terms of data throughput, timing distribution and system reliability. The Phase-II Chamber Service Module (CSM) is a key component of the upgraded Monitored Drift Tube (MDT) trigger and readout system, providing a high-speed interface between the front-end electronics and the backend systems. This paper describes the design and implementation of the Phase-II CSM, together with its validation. The results show that the CSM supports two independent optical uplinks, each operating at a line rate of 10.24 Gbps, together with clock distribution and slow control in the expected operating environment. Integration with small-diameter MDT (sMDT) chambers and tests with the prototype L0MDT trigger system are also presented. The CSM boards are now in production and will be used for installation and integration during the upcoming LHC Long Shutdown.
