KEK 的 8-GeV 直线加速器为 KEKB-HER、KEKBLER 和 Photon Factory 的三个环形加速器提供电子和正电子。 KEKB 和 PF 设施同时对这些环进行补充注射，以获得最终的实验结果。新构建了一个基于事件的快速控制系统，与现有的EPICS控制系统重叠。新系统利用 MRF 的事件模块和其他几种技术在全球范围内控制远程设备。事件系统可实现从皮秒到毫秒范围的快速控制，而传统的 EPICS 系统则涵盖较慢的控制。事件系统每 20ms 脉冲全局驱动 100 多个参数，以生成具有三倍不同能量和 100 倍不同电荷的光束。并同步观测500多个参数，保证光束运行。该系统还支持未来的加速器综合体，例如 SuperKEKB。文中详细介绍了软硬件结构的详细设计以及梁的运行经验。
The 8-GeV linac at KEK provides electrons and positrons to three ring accelerators of KEKB-HER, KEKBLER and Photon Factory. Simultaneous top-up injections to those rings are carried for the ultimate experimental results at the both KEKB and PF facilities. An event-based fast control system was newly constructed overlapping the existent EPICS control system. The new system controls the distant equipment globally utilizing event modules from MRF and several other techniques. The event system enables fast controls from picosecond to millisecond range, and the conventional EPICS system covers slower controls. More than 100 parameters are driven globally by the event system every 20ms pulse in order to generate beams with three-times different energies and 100-times different charges. And more than 500 parameters are observed synchronously to ensure the beam operation. The system enables the future accelerator complex such as SuperKEKB as well. This paper describes the detailed design of the hardware and software structures, and beam operation experiences.
