摘要
文章对爆炸发射阴极的物理机制进行了阐述,着重对爆炸发射阴极的各种特性进行了介绍,包括阈值电压、发射均匀性、等离子体闭合速率、阴极寿命等.并且对研究爆炸发射阴极特性所采用的理论和测量方法进行了介绍,给出了目前阴极材料使用中存在的问题.
The physical mechanism of explosive emission cathodes is reviewed. The properties of these cathodes are introduced in detail, including the threshold voltage, uniformity, plasma closure velocity, and life time. The experimental methods used in their study are also described, and some suggestions to improve their properties ale given.
