摘　　要：基于雪崩三极管的脉冲源具有稳定度高、脉冲窄、上升时间短等优点,分析了雪崩三极管脉冲源稳定度的影响因素。采用适当的优化措施提高了稳定度指标,设计了高稳定度的雪崩三极管脉冲源,脉冲峰值电压1500V(50Ω负载),脉冲宽度1ns,上升时间200ps,具有很高的稳定度指标:短时抖动小于30ps,长时漂移小于100ps/min,峰值电压和脉冲宽度抖动小于1%。通过对改进脉冲电路的充电形式,实现了重复频率为60kHz的脉冲输出。The merits of the full-solid-state pulser, based on avalanche transistor, are high stability, narrow pulse and short rise-time. In this paper, the effect factors of the stability are analyzed. Some optimizing measures are used to improve the stability, and a high-stability pulser is designed, peak voltage is 1 500 V, pulse width is 1 ns, and the pulse width jitter is less than 1% and the peak voltage jitter is less than 1%. By improving the charging form of pulse circuit, the output pulse with repetition of 60 kHz is realized.
