摘要
针对三代微光像增强器的GaAs阴极灵敏度下降,分析真空残气对阴极发射性能的影响。实验结果表明,有害气体是造成阴极灵敏度下降的主要因素。
As for the GaAs cathode sensitivity decrease of the third generation LLL image intensifier, the effect of the residual gas on emission property of GaAs cathode in vacuum is analysed. Experimental results show that the harmful gas is the main factor of the cathode sensitivity dropping.
