运行模式
Operation mode
模式说明 Mode declaration 注入器老练模式
Commissioning mode
停止驱动激光的定时输出，关闭激光光闸，正常情况下，保持功率源工作状态。信号报警不锁存，可自动复位 The trigger for driver laser should be inhibited, and the laser shutter should be closed. Keep the solid-state amplifiers working if the related interlock signals are normal. The alarm signals are not latched, and the function of automatic reset can be implemented. 电子枪运行
Electron gun operation mode
电子枪段建立正常的联锁条件，旁路电子枪段之后的联锁输入 All the signals after the e-gun should be bypassed, and the normal interlock condition is established for e-gun. 注入器运行
Injector operation mode
注入器段建立正常的联锁条件，旁路注入器之后的联锁输入 The normal interlock condition is established for injector, and all the signals after injector should be bypassed. 低重频模式
Low repetition rate mode
禁止激光的定时触发频率超过50 Hz The repetition rate of trigger for driver laser should be less than 50 Hz. 高重频模式
High repetition rate mode
禁止截面靶在线工作，禁止丝扫描设备工作在低速状态 The profiles are forbidden to work on line, and wire scanners are forbidden to work in slow speed.
