摘要
扫描型变象管Ｘ射线皮秒分幅相机在强Ｘ射线情况下，由于空间电荷效应，像质变坏，甚至无法工作。本文简述了ＭｇＦ２光阴极材料的性能，首次在Ｘ射线皮秒变象管分幅相机上的应用结果：降低了强Ｘ射线源情况下分幅管内空间电荷效应的影响，并获得了清晰的物理图象。
Image distortion of the electro-optical tube X-ray framing camera becomes serious for intense X-ray pulse operation because of the space charge effect. This paper describes the characteristic of MgF2 photocathode and its first application in the framing camara. The space charge effect has been reduced and the clear pictures have been obtained for the intense X-rays.
