Streak image tube with wide sweep range and high temporal resolution

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.
