Precise synchronization of UV laser probe system with the load current of accelerator

In this article, an Nd∶YAG laser is used as light source of the probe system. The main switch signal of the pulsed accelerator can be chosen with specific time delay to trigger the laser system after a 100 ns innate time delay of the laser outer-triggered controlling circuit is attained. In the experiment the triggering signal of Q-switch, the laser light signal, the triggering signal of main switch of the accelerator and load current are temporally associated with an oscilloscope. The delay time of the adjustment system is based on results of measurement of the time association. The synchronization of 9.6 ns between light pulse of probe system and accelerator load current is realized.
