Abstract

A new design concept of the electron-optical focusing system for widescreen single-frame and streak image intensifier tubes with the gating-deflection-type shutter system is presented. The effectiveness of a 'quasispheric' immersion objective for forming of widescreen image has been studied using a numerical model. This objective is used in a new LD-F-5 tube with a useful photocathode area of 40 mm and LD-S 10 streak image inverter tubes. The spatial resolution of LD-F-5 tubes is about 25lp/mm under the strobe pulse duration of about 10 ns and voltage +/- 350 V.
