Influence of gas switch jitter on output characteristics of single modular fast linear transformer driver

The triggered breakdown delay time distribution of the gas switch was presented for the 1 MA/100 ns fast linear transformer driver(FLTD), consisting of 40 parallel bricks. The delay time and switch jitter were simulated by random arrays generated by MATLAB program. The influence of the switch jitter on the rise time and amplitude of the FLTD's output current has been studied based on the simplified second-order circuit of the FLTD brick. Simulated results indicate that the peak of the output current is about 996 kA at 90 ns with a rise time of about 54 ns (10% to 90%) in the ideal situation of 0 ns switch jitter. The rise time of the output current increases by about 14% and the peak decreases by 2% when the switch jitter is about 10 ns. The rise time increases by about 38% and the peak decreases by 5% when the switch jitter is about 20 ns.
