摘　　要：介绍了用于最近成功运转的高功率，强流密度，低发射度，高亮度虚火花电子束源的强流测量方法──自积分线圈测量法。给出该线圈的实用化设计及其标定方法。实验表明，这种线圈在强流环境里特性很好，虚火花电子束的束质量比冷阴极电子束好得多。A self-integrating coil measurement of intense current in a successfully-operated pseudospark electron beam source characteristic of high power,intense current density,low emittance, and high brightness is introduced.The practical design and calibration ways are given. Experiments show that this coil behaves very well in the case of intense current;the quality of the pseudospark electron beam is much better than that of the cold cathode one.
