摘要
在紧凑加速器的重复运行模式下,推导了相邻脉冲间初级电容上初始电压的递推关系,得到了平衡态下初级电容上初始电压满足的方程,给出了由非平衡态到平衡态的过渡时间的计算方法,讨论了充电晶闸管导通时间不依赖于气体火花隙主开关击穿电压的条件,介绍了调制器系统重复运行实验调试的方法和步骤。通过理论分析和实验研究,通过选择合适的晶闸管导通时间,可以使重频运行从第1个脉冲开始即达到平衡态。
Recurrence relations of the initial voltages across the primary capacitor between adjacent pulses are derivated based on the sequence processes of discharge and recharge of the primary capacitor in repetitive mode for a compact accelerator. The equation of the initial voltage across the primary capacitor in steady state is obtained. And the transition time or the number of the transition pulses between the unsteady state and the steady state can be calculated. The condition, under which the charge thyristor switch＇s turn-on time is independent of the gas spark switches breakdown voltage, is theoretically discussed and experimentally obtained. Furthermore, the corresponding methods and steps are presented to guide the experiments. From the theoretical analyses and experimental investigations above, the conclusion is drawn as follows： by choosing appropriate turn-on time of the charge thyristor switch, the steady state of the initial voltage across the primary capacitor can be obtained since the first pulse.
