Paper Abstract

Fluorescence screen of Image intensifier is the key part to imaging quality of micro light and ultraviolet Image intensifier. To research the performance testing and analysis of Fluorescence screen seems more important in China. The research will help to understand the performance of Fluorescence screen, know where improvement should be made and then a best performance entire tube will be achieved. This article will do the theory analysis to part of testing instrument, area source electron gun's uniformity. Electron gun consists of taper tantalum filament, vacuum environment and axial symmetry high pressure static field. The uniformity of hot electron emission of filament has been analyzed. Upon that, this article will specially analyze the uniformity of electron in the effective area after they go through the axial symmetry high pressure static field and get accelerated.
