Abstract

Abstract

The accurate control technology for 24 modules of the Primary Test Stand (PTS) and the experimental results are given in this paper. The synchronicity of 24 lines pulsed current is controlled by 24 laser trigger switches. The current waveform can form through adjusting laser time easily. 24 laser trigger switches are triggered by 12 Q- switched Nd: YAG fourth harmonic 266 nm laser, i.e., two laser switches are triggered by one laser. The experimental results show that the jitter of the laser trigger system is less than 1.0 ns, the jitter of switch is less than 1.5 ns. The load current is 9.8 MA and the rising time of current is 75 ns under 65 kV charging voltage, when 24 modules are triggered synchronously. The adjusting range of rising time of current get to about 600 ns, 5.5 MA in PTS. The measured result of current waveform is consistent with the simulation result. The current waveform is repeatable for same load.
