As a temporary substrate for preparing the Al2O3 ion barrier film, the continuity of the organic membrane significantly affects the compactness of the ion barrier film, while the continuity of the organic membrane prepared by water surface spreading method is directly affected by the non-solvent component. In this paper, the effect of ultrapure water, non-deionized water, NaCl solution, NaOH solution and HCl solution as non-solvent component on the compactness of the organic membrane and ion barrier film are studied. The results show that NaCl solution is the best non-solvent component for the preparation the most continuous organic membrane and the most compact Al2O3 ion barrier film.
Different causes of similar view defects of ion barrier MCP were studied. Select ion barrier MCP with dark spots and bright spots. By analyzing its view and its own quality during operation, the different causes of the similar view defects of the ion barrier MCP were obtained. The analysis leads to solutions for different defects, which have a very positive effect on the improvement of the view of image intensifier.
