Abstract

The Run Control System of the Compact Muon Solenoid (CMS) experiment at CERN's new Large Hadron Collider (LHC) controls the sub-detector and central data acquisition systems and the high-level trigger farm of the experiment. It manages around 10,000 applications that control custom hardware or handle the event building and the high-level trigger processing. The CMS Run Control System is a distributed Java system running on a set of Apache Tomcat servlet containers. Users interact with the system through a web browser. The paper presents the architecture of the CMS Run Control System and deals with operational aspects during the first phase of operation with colliding beams. In particular it focuses on performance, stability, integration with the CMS Detector Control System, integration with LHC status information and tools to guide the shifter.

首次使用CMS运行控制系统

欧洲核子研究中心新型大型强子对撞机(LHC)紧凑型介子螺线管(CMS)实验的运行控制系统控制着实验的子探测器和中央数据采集系统以及高水平触发场。它管理大约10,000个应用程序，这些应用程序控制自定义硬件或处理事件构建和高级触发器处理。CMS运行控制系统是一个运行在一组Apache Tomcat servlet容器上的分布式Java系统。用户通过web浏览器与系统交互。本文介绍了CMS运行控制系统的体系结构，并讨论了碰撞光束运行第一阶段的操作问题。特别着重于性能、稳定性、与CMS探测器控制系统的集成、与LHC状态信息的集成以及引导移位器的工具。
