Synchronized trigger system for fast linear transformer driver

A conceptional design of synchronized trigger system for fast linear transformer driver is introduced, which is based on single transmission line pulse forming technology. The trigger system consists of Marx generators, pulse forming lines, main switches, transmission lines and output cables. With the equivalent circuit model, the relationship between Marx generator and pulse forming line is studied. As multiple pulse forming lines are driven in parallel, the number of trigger pulses and the efficiency of energy increase, but the amplitude of trigger pulses decreases. The impedance and number of output cables affect the amplitude as well. With increasing the serial number of cable, the amplitude decreases gradually. As the impedance of transmission line increases, the attenuation rate of the amplitude increases consequently. The trigger signals can be also led out at the same time. When single pulse forming line is driven, 60 trigger signals can be obtained with the amplitude of 293 kV and rise time of 11 ns. When five pulse forming lines are driven in parallel, the amount of trigger signals can reach 300, the amplitude of the pulses is 151 kV and the rise time is 11 ns. (authors)
