摘要
SDUV-FEL是进行FEL新原理测试的实验装置,其电源控制系统是在EPICS系统架构下开发与集成实现的基于Ethernet的分布式控制系统。本文介绍了系统的基本结构与工作原理,描述了针对直接I/O控制模拟电源、数字化控制电源、GPIB接口电源设计的控制方案,以及基于嵌入式系统的IOC控制器开发、电源控制实时数据库和图形化操作界面的设计。在已进行的多项FEL实验中,电源控制系统的性能得到了充分检验。
Background： The power supply control system of Shanghai Deep Ultra-Violet Free Electron Laser （SDUV-FEL） test facility is an Ethernet-based distributed control system developed and integrated using the Experimental Physics and Industrial Control System （EPICS） toolkit. Purpose： The SDUV-FEL test facility has been integrated to test new FEL principles. Methods： The power supply control system provides control scheme for direct I/O controlled analog power supply, full digital-controlled power supply and Agilent commercial power supply with GPIB interface. Embedded I/O controller, runtime database and graphic operation interface are applied in this system. Results： The high performance of system demonstrated that the SASE and seeded FEL experiments were carried out in the past years. Conclusions： The power supply control system of the SDUV-FEL test facility has achieved long-term stable running, which is useful for future similar facility.
