Abstract :
An experimental measurement of the effects of oxygen, water, carbon dioxide, methane, hydrogen and helium gases on the different process stages of the cathode ray tube are presented. Using the residual gas analysis results, exhaust timing, getter flashing, and emission aging could be adjusted for obtaining an optimal process control. The tube size of 15 inch and 17 inch are measured in this study. The test procedure, the experimental set-up, and the analysis results are proposed. The methodology of the measuring program could be constructed for future study and assurance of the quality on the different process stages could be obtained
