| 摘 要： | 用于直线感应加速器的3.5 MeV注入器脉冲功率系统采用了感应叠加原理。整个系统包含了脉冲形成系统、触发系统以及感应腔负载。脉冲形成系统主要由Marx发生器和Blumlein脉冲形成线组成，产生12个脉宽约90 ns，幅度约200 kV的高压脉冲，通过12个感应腔和变阻抗阴阳极杆，在阴阳极间隙处产生3.5 MV的二极管电压，由天鹅绒阴极发射强流电子束。触发系统主要由两级触发开关构成，严格控制12个高压脉冲的输出时间，时间分散性统计值小于1 ns(动作时间抖动)。采用该脉冲功率系统注入器能产生能量约3.5 MeV，电流2～3 kA的强流电子束。

| Abstract: | A 3.5 MeV injector for linear induction accelerator has been built up at Institute of Fluid Physics, China Academy of Engineering Physics. The injector is based on the principle of inductive adder. It consists of 12 induction cells. Seven induction cells are on the cathode stem side, which are connected in series, and provide about 2 MV on the cathode of the diode. The other five are connected in series on the anode stem side and provide about 1.5 MV on the anode of the diode. A 3.5 MV pulsed power system to provide energy for the injector has been designed, which consists of two Marx generators,12 water insulated Blumleins, and trigger system. Charge voltage of each water insulated Blumlein is 200 kV. A 300 kV/90 ns high voltage pulse is fed into one induction cell since load impedance is higher. The pulsed power system can generate an intense electron beam with 2~3 kA. |
