摘要
采用双磁透镜设计时间展宽分幅变像管，对其空间分辨特性进行模拟和测试。采用2#分辨率板测试像管空间分辨率，以及大面积阴极测试像管在离轴位置的空间分辨能力。测试结果表明，双磁透镜像管的空间分辨率为74 μm；在图像缩小1 倍时，能有效分辨阴极距离中心轴位置30 mm 的信息。像管的空间分辨率和在阴极离轴位置的分辨能力都优于单磁透镜像管。因此，双磁透镜能有效提高时间展宽分幅变像管的空间分辨特性。
Abstract
The pulse-dilation framing tube using the double magnetic lenses is designed and the performance of spatial resolution is simulated and measured. The spatial resolution of tube is measured through the 2# plate. The spatial resolution at the off-axis position is tested through a large cathode. The measurement results show that the spatial resolution of tube is 74 μm, and the 30 mm off-axis position on the cathode is resolved while the image is demagnified 1 times. The spatial resolution and the spatial resolving power at the off-axis position are better than the tube using the single magnetic lens. Therefore, the spatial resolving performance of pulse-dilation framing tube is improved by the double magnetic lenses.
