GaAs light source

The paper reviews the ion barrier adopted in 3~(rd) generation image intensifier,which has dual effects on the GaAs photocathode,protecting it from being damaged by ion feedback,at the same time degrading the quantum efficiency.

介绍了国外最新的三代像增强器,以及使用优化改进的高性能微通道板显著减薄甚至彻底去除微通道板离子反馈膜的方法,该方法能维持砷化镓光阴极足够长的工作寿命,还介绍了最新发展的体导电微通道板和硅微通道板。
