| 摘 要： | 采用箍缩反射离子二极管，使阴极发射的电子多次穿过阳极膜并向轴线箍缩，增加了它在二极管中的平均渡越时间，从而提高了离子流产生效率。根据顺位流模型。设计了２００ｋＶ强流脉冲离子束加速器的箍缩反射离子二极管，得到了峰值为１．６ｋＡ，脉宽约２０ｎｓ的离子束流。

| Abstract: | Pinch diodes are used extensively for ion beam production. In pinch reflex ion diodes, electrons are emitted from the cathode reflex through the anode foil. This is a result of their interactions with the azimuthal magnetic field due to current flowing through the central button. Further enhancement of the electron path length and average transit time are obtained, improving the ion production efficiency. According to the parapotential flow model, a pinch reflex ion diode is designed using the 200 kV intense pulsed ion accelerator. The ion beam peak current of 1 6 kA is obtained with a pulse width of about 20 ns. |
