Abstract

The current of electron flux, impinging phosphor screen of the MCP-image intensifier tube with profimily focusing, is produced by amplified flux of electron image, that corresponds radiation flux strike to the photocathode. Screen luminance is proportional to this current. However, in real tube, phosphor screen is subjected to bombardment of electron fluxes that initiated main, and degrading image quality. In result of analytical research is presented mathematic model of summarized electron current, produced by both main and collateral physical processes. This model estimates a part of all physical processes to summarized current. From this model be conclude of about necessary of collateral physical processes suppression to enhance image quality on tube screen. Decreased and suppression collateral physical processes influence may be reached due design elements optimization and high level of technological operation.
