亚纳秒触发脉冲延时分配器设计

The subnanosecond trigger pulse delay and assignation apparatus for storage ring injection at SSRF

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。

A trigger pulse delay and assignation apparatus, using an appropriative and controllable delay line chip, has been developed for SSRF storage ring injection system. With the input being one light pulse, and the outputs being 4 electric pulses, the delay is independent and adjustable, and the rise time is short and jitter is low. The delay is 0.25-ns steps, with an adjustable range of up to 64 ns. In addition to the fimction of pulse delay, the apparatus also has the interlock fimction and LCD display. It can be operated on keyboard, and can be controlled remotely through its serial port.
