欧洲核子研究中心（CERN）的大型强子对撞机（LHC）将升级为高亮度大型强子对撞机（HL-LHC），这会提高粒子碰撞率，进而对探测器读出提出更高要求。此次升级的关键部件是新型CMS径迹探测器，其硅传感器将产生总计约10 TB/s的数据，这些数据必须被高效路由至处理系统并在存储前完成过滤。Serenity-S1是一款基于AMD Virtex UltraScale+ VU13P FPGA的ATCA读出与数据处理卡，配备128个高速串行收发器；20个12通道Samtec FireFly光模块可提供多达120个发送通道和120个接收通道，线路速率最高达25 Gb/s，另有1个额外光模块支持CMS径迹探测器链路，单通道速率最高达10 Gb/s。模块化光布局结合大尺寸FPGA，使Serenity-S1适用于CMS内部及外部的多种应用；ATCA为其在CMS服务 cavern 中运行提供所需的供电与冷却。底层管理和IPMI接口由OpenIPMC夹层板提供，而运行AlmaLinux 9的AMD Kria K26系统级模块则执行更高级别的板管理与应用控制。固件与软件框架提供通用基础设施，让用户可专注于特定应用逻辑。本文介绍了Serenity-S1的硬件、固件与软件架构，以及其在CMS径迹探测器集成与研发活动中的部署情况。
英文摘要
The CERN Large Hadron Collider will be upgraded to the High-Luminosity LHC, increasing the particle-collision rate and the demands on detector readout. A key element of this upgrade is the new CMS Tracker, whose silicon sensors will generate data at an aggregate rate of about 10 TB/s. This data must be routed efficiently to processing systems and filtered before storage. Serenity-S1 is an ATCA readout and data-processing card based on an AMD Virtex UltraScale+ VU13P FPGA with 128 high-speed serial transceivers. Twenty 12-channel Samtec FireFly optical modules provide up to 120 transmit and 120 receive channels at line rates of up to 25 Gb/s, while an additional optical module supports CMS Tracker links at up to 10 Gb/s per channel. The modular optical layout, combined with the large FPGA, makes Serenity-S1 suitable for several applications within and beyond CMS. ATCA provides the power and cooling required for operation in the CMS service cavern. Low-level management and the IPMI interface are provided by an OpenIPMC mezzanine, while an AMD Kria K26 system-on-module running AlmaLinux 9 performs higher-level board management and application control. Firmware and software frameworks provide common infrastructure so that users can focus on application-specific logic. The paper describes the hardware, firmware and software architecture of Serenity-S1 and its deployment in CMS Tracker integration and R&D activities.
