介绍了上海光源储存环注入系统冲击磁铁定时触发脉冲延时分配器的设计和研制。采用可控专用延时芯片设计了该触发脉冲延时分配器,实现1路光脉冲输入,4路延时独立可调的快前沿低抖动电脉冲输出,输出脉冲延时调整步长0.25 ns、可调延时范围64 ns。除具有延时功能外,还具有联锁保护、输出脉冲状态、联锁输入状态显示等功能,不仅可以通过仪器面板操作,还可以通过RS232接口遥控。
The design and development of the timing trigger pulse delay distributor of impacting magnet in Shanghai light source storage ring injection system are introduced. The controllable dedicated delay chip is used to design the trigger delay divider to realize 1 optical pulse input and 4 fast-adjustable low-jitter electrical pulse outputs independently adjustable in delay time. The output pulse delay adjustment step is 0.25 ns, Adjustable delay range 64 ns. In addition to the delay function, but also with interlock protection, the output pulse status, interlock input status display and other functions, not only through the instrument panel operation, but also through the RS232 interface remote control.
