SPS电源转换器控制向LHC时代的发展
Evolution of the SPS Power Converter Controls towards the LHC Era
摘要：
到90年代末，欧洲核子研究中心质子加速器（SPS）的功率转换器控制系统（Mugef）已经完成了全面的现代化改造。这导致在LynxOS实时操作系统下，在VME环境中开发了用于功能生成、测量和I/O的新硬件。这提供了一个平台，在这个平台上可以为大型强子对撞机（LHC）时代的未来操作开发扩展。本文介绍了这些扩展，特别是一个快速的监视和联锁系统，用于监测功率转换器的输出电流。这对于SPS传输线TI 2和TI 8到LHC的安全操作以及未来的类似应用是强制性的。概述了用于处理功率变换器的各种故障模式和及时激活联锁的策略。目前正在开发的新的SPS控制基础设施将为Mugef系统带来新的操作模式。与所提出的中间件的集成必须在结构化的演进中进行，同时保持与当前使用的兼容性。
英文摘要：
By the end of the nineties, the power converter control system (Mugef) of the CERN proton accelerator (SPS) had undergone a complete modernization. This resulted in newly developed hardware for function generation, measurement and I/O in a VME environment, under the LynxOS real-time operating system. This has provided a platform on which extensions can be developed for future operation in the Large Hadron Collider (LHC) era. This paper describes some of these extensions, in particular a fast Surveillance and Interlock system for monitoring the power converter output currents. This will be mandatory for the safe operation of the SPS transfer lines TI2 & TI8 to LHC and for similar applications in the future. The strategies employed to cope with various failure modes of the power converters and the timely activation of the interlock are outlined. The new SPS controls infrastructure now under development, will give rise to new modes of operation for the Mugef systems. Integration with the proposed middleware must be undertaken in a structured evolution, while retaining compatibility with the current usage.
