摘　　要：介绍了基于Marx发生器原理设计的脉冲X光机,在设计Marx发生器时选择了正负极充电,极间电容耦合为Z形回路的Marx发生器线路,采用低抖动场畸变开关和固体低感电阻为结构元件,低感陶瓷电容作为储能元件。Marx发生器通过高压电缆和X射线管连接,得到脉冲X光机特性为：输出电压100-150kV;0.25 m处的X射线剂量约为90.3×10^-7C/kg;脉冲宽度约为70 ns。具有性能稳定、结构紧凑、使用方便等特点。A 150 kV pulsed X-ray system designed according to the bipolar charged Marx generator was introduced.Low jitter electric field-distortion switches,low inductance solid-state resistors and ceramic capacitors were used in the pulse generator to shorten the pulse risetime and width.The Marx generator was connected to the X-ray tube through the high-voltage cable.Then it can output a pulse with 100～150 kV amplitude,and drive the X-ray tube to produce a flash X-ray with 90.3×10^-7 C/kg dose and 70 ns pulse width at 0.25 m.The X-ray system is easy to operate with stable performance and compact structure.
