Effect of Mass Pollution of the Micro-Channel Plate on Function of II Generation Invert Lowlight Level Tube

In order to resolve the problem of low eligible rate of producing tube in research ofⅡgener- ation invert lowlight level tube,it makes analysis on craft quality of disposing process for micro-channel plate and outgas component.The result shows ineligible quality of micro-channel plate,surface contamina- tion and low consensus of function are main causes to result in low sensitivity,field dark spots,low resolu-tion,and large back grade.We have taken measure to clean and disposing craft process of removing gas of oil free vacuum stove.These methods eliminate the pollution of micro-channel plate that is caused by the craft process.We have researchedⅡgeneration invert lowlight level tube successfully that the whole func-tion is total eligible.
