Three different gating manners for a typical second generation converter tube (18 mm,ITT-F4111 type) are compared. A new control circuit for gating the photocathode of the image intensifier is developed, and it generates high amplitude nanosecond pulses. The experimental result shows that a camera exposure time of about 2 ns has been obtained with this gating generator. The matching of the gating generator with the image intensifier is also discussed. a simple and efficient method is presented to eliminate the multi-exposure effect which must be avoided in single-shot photography. %U http://www.alljournals.cn/get_abstract_url.aspx?pcid=5B3AB970F71A803DEACDC0559115BFCF0A068CD97DD29835&cid=1319827C0C74AAE8D654BEA21B7F54D3&jid=EFC0377B03BD8D0EF4BBB548AC5F739A&aid=595F036A17E6DBDD&yid=36250D1D6BDC99BD&vid=B31275AF3241DB2D&iid=B31275AF3241DB2D&sid=8143FF92EEF26F96&eid=03436AC72A659ACA&journal_id=1009-5896&journal_name=电子与信息学报&referenced_num=0&reference_num=5
