摘　　要：　分析了脉冲线加速器在放电过程中产生的预脉冲电压现象。为了减少预脉冲电压引起的等离子体发射对正常状态的影响,采用了一种冷阴极撬棒管,将它与阴极杆相连。实验证明在采用了这种器件后,预脉冲电压可以从150kV左右减少到50kV。相对论返波管和相对论磁控管的性能得以显著改善。The prepulse phenomena in the discharge process of accelerator are analyzed in this paper. The prepulse will result in forming plasma, and further affect the diode performance. To remove or reduce this effect, a crowbar tube with cold cathode was adopted in the accelerator. The results show that prepulse voltage decreased from about 150 kV to 50 kV after adopting crowbar tube. The output power of relativistic backward-wave oscillator increased from 50 MW to 250 MW under the same condition. The frequency of relativistic magnetron tended to be reasonable obviously too.
