在北京正负电子对撞机(BEPC)中用于同步辐射X光研究的插入件4W1磁铁由主线圈绕组和补偿线圈绕组组成,由两台高精度直流电源(主电源和辅助电源)供电.2004年11月,BEPC开机使用的两台主电源和辅助电源是重新设计制造的,采用新的控制接口PSI和控制器PSC进行控制.这套系统是在BEPCⅡ磁铁电源控制样机PSC/PSI完成的基础上仅用1个月的时间完成的.在运行初期经过多次调试和修改后,安全无故障运行历时4个月,为同步辐射提供两条X光束线,保证了用户顺利地进行实验.它是第一个投入运行的BEPCⅡ储存环控制系统的一个新系统.介绍了基于EPICS平台开发的4W1磁铁电源新的控制系统和4W1磁铁升降流的特点以及控制升降流应用程序的研制.
