Abstract
High-energy area source electron gun is a key component in image intensifier screen testing instrument. On the basis of the analysis of relationship between thermal emission characteristics, the shape of filament and the density of thermal electron emission, high-energy area source electron gun is designed. The distribution of electric field and electronic tracks are theoretically analyzed and calculated to make it has features of dispersing, uniform, converging and submerging. By testing a standard screen, correct the structure of high-energy area source electron gun to meet the requirements of test indexes and obtain reasonable high-energy area source electron gun. Its successful development provides effective technical support to the luminous screen test for uniformity, brightness, luminescence efficiency and afterglow and to the examination of other components (such as MCP parameters)of Low-light Image Intensifier.
