一种新型的“条纹”管已研制成功,它用于研究高速光学瞬变过程,例如,在加利福尼亚大学的劳仑斯利物莫尔实验室把它用于分析Shiva激光聚变。该管把具有直接读出特点的CCD与光快门象管的高速偏转系统结合在一起。从而能及时给出适于数据处理的电子信息读出。这种管子的前段是一象增强器级,它具有对1.06μm激光灵敏的S-1红外光电阴极。当激光束入射到光电阴极上时,发射出的电子流被加速,并且被加入偏转电极上的扫描电压偏转。偏转的光束撞击CCD,由每个光电子产生出数千个电子—空穴对。然后,扫描电荷分布图,从而提供一幅激光束的时间——强度分布图。
A new type of “stripe” tube has been developed that is used to study high-speed optical transients, such as the Shiva laser fusion at Lawrence Livermore Laboratory at the University of California. The tube combines a direct readout CCD with a high speed deflection system of a photo shutter tube. Which can be timely given for data processing electronic information read out. The front section of this tube is an image intensifier stage with an S-1 infrared photocathode sensitive to a 1.06 μm laser. When the laser beam is incident on the photocathode, the emitted electron current is accelerated and deflected by the scanning voltage applied to the deflection electrode. The deflected beam strikes the CCD, producing thousands of electron-hole pairs per photoelectron. Then, the charge profile is scanned to provide a time-intensity profile of the laser beam.
