Abstract: The time sequence control of the Marx generators, laser-triggered gas switches(LTS), self-break water switches (WS) which affects the PTS synchronization was studied. Synchronization of Marx generators affects energy efficiency of transmission process and PTS synchronization is mainly determined by LTS and SW. The key to achieve precise synchronization of the PTS is to independently and precisely adjust the trigger time of the 12 lasers, each laser is split into two beams used to trigger two laser triggered gas switches (LTGS). The LTGSs in the upper layer of PTS are triggered 20 ns later than the LTGSs in the lower layer to compensate the transmission time difference caused by length different between the transmission lines in the upper layer and the lower layer. The gap distances of the electrodes of the self-breaking water switches are set to suitable values to adjust the switching time. Experiments show that the synchronization jitters of the Marx generators, the main switches, the water switches, and the tri-plate transmission lines are 11, 4, 10 and 6 ns respectively. The 24 modules were well synchronized for the experimental shots. Currents of magnetically insulated transmission line (MITL) and load showed good repeatability with similar load.
