Accession number: 20154701593549 Title: Simulation research of electrostatic field of MCP input in proximity image intensifier Authors: Song, De1, 2 Email author songde614@163.com; Piao, Xue2; Bai, Xiaofeng1; Liu, Chunyang2 Author affiliation: 1 Science and Technology on Low-Light-Level Night Vision Laboratory, Xi'an, China 2 College of Science, Changchun University of Science and Technology, Changchun, China Source title: Hongwai yu Jiguang Gongcheng/Infrared and Laser Engineering Abbreviated source title: Hongwai yu Jiguang Gongcheng Infrared Laser Eng. Volume: 44 Issue: 10 Issue date: October 25, 2015 Publication year: 2015 Pages: 2981-2986 Language: Chinese ISSN: 10072276 Document type: Journal article (JA) Publisher: Chinese Society of Astronautics Abstract: The electrostatic distributions between Micro-channel plate (MCP) and photocathode will affect the movement locus of photogenerated electrons and the proximity image intensifier's performance. However the distributions of electrostatic fields and equipotential lines were complex due to a lot of micro-channel in the micro channel plate. So this paper simulated the electrostatic distribution of MCP input in proximity focusing low-light-level image intensifiers by the finite element simulation analysis software Ansoft Maxwell 3D. How the electrostatic distribution of MCP input were affected by micro- channel diameter, angle of micro-channel, minimum interspacing between micro-channels walls and flaring-condition of the input end of the channel were analyzed according to the simulation result. Meanwhile, the photogenerated electrons' trajectory and image intensifier's resolution affected by the change of electrostatic distribution were discussed. This study will provide a theory foundation for the fabrication of the high quality MCP. ©, 2015, Editorial Board of Journal of Infrared and Laser Engineering. All right reserved.
