| Abstract: | The merits of the full-solid-state pulser, based on avalanche transistor, are high stability, narrow pulse and short rise-time. But the disadvantage of this pulser is that its output power is low, thus Marx circuit is used to improve the peak-voltage. In this paper, the effect factors of the time-stability and shape-stability are analyzed, some optimizing measures are used to improve the stability, and a high-stability pulser is designed. The pulser’s peak voltage is 2 000 V, pulse width is 5 ns, repetition frequency is higher than 25 kHz, and the pulse width jitter is less than 1% and the peak voltage jitter is less than 1%. |
