Imaging and streaking tubes including a lid for covering an aperture in a wall separating the tube envelope into spaces during fabrication thereof

摘要

An imaging tube for amplifying and observing a diminished light image and a streaking tube for analyzing the light intensity distributions of light sources with elapsing of time. In order to avoid adhesion of alkali metal to the micro-channel-plate in fabrication of the imaging tube and to avoid adhesion of alkali metal to the deflection electrode in the streaking tube, a separation wall and a lid movable on the separation wall are used.
