摘要
为改善大偏转角度的偏转像质,设计了一种高时间分辨、大扫描长度的扫描变像管电子光学和行波偏转系统。对变像管后加速技术进行了实验研究,结合图像外增强技术,解决了大面积扫描图像的探测灵敏度问题,达到了同时扩展扫描变像管的时间量程和提高时间分辨力的目的,研制出了宽时间量程、高时间分辨力的扫描变像管。初步实验表明,在量程为5 ns时,时间分辨力达到5 ps,也就是时间分辨力与时间量程之比达到1/1 000。
Abstract
Some efforts have been made on developing an optical streak image tube: creating a unique electro-optics configuration of streak image tube with large sweep range and high temporal resolution, designing a proper travelling-wave deflection system to improve the deflecting image quality at large deflection angle, and combining the post-acceleration and external image intensifying technique to solve the limitation on detection sensitivity in large streaking area. Preliminary experiments show that the image tube’s temporal resolution is 5 ps within 5 ns sweep range, i.e. the ratio of temporal resolution to time range reaches 1/1 000.
