研制了一款新型磁聚焦成像电子束时间展宽分幅相机，研究了其空间分辨率与磁聚焦透镜数目及电流间的关系，实验结果表明：采用三个磁聚焦透镜且电流适合时，相机的空间分辨率最高；离轴越远，空间分辨率越低。研究了相机的空间分辨率与电压间的关系，发现空间分辨率随着阴栅极间电压的增大而提高。该新型分幅相机成像面为一个曲面，整个阴极面不能同时清晰成像。采用电子束时间展宽技术后，该新型分幅相机的时间分辨率提高至11 ps；当成像倍率为2∶1时，相机的静态空间分辨率为5 lp·mm-1。

A novel framing camera based on multiple magnetic focusing imaging and electron pulse time dilation is developed. The relationship between the spatial resolution and the number of the magnetic focusing lenses as well as that between the spatial resolution and the current is investigated. The experimental results show that the spatial resolution is the best when three magnetic focusing lenses and the suitable current are chosen. The larger the off-axis distance is, the worse the spatial resolution is. The relationship between spatial resolution and bias voltage is investigated and it is found that the spatial resolution improves with the increase of the bias voltage between the photo-cathode and the mesh. The image plane of this novel framing camera is a curved surface and the whole cathode surface cannot be simultaneously imaged. The temporal resolution is improved to 11 ps when the time dilation technology is introduced and the static spatial resolution is 5 lp·mm-1 when the image ratio is 2∶1.
