ABSTRACT:
In order to achieve a strong and safe construction, the tube wall of an image intensifier tube is provided with at least two comparatively heavy supporting rings. On one of these rings a cup-shaped or spherical, vacuum-tight sealing entrance window of X-ray transparent metal is secured. As a result of the use of an adapted electrode construction and a concave exit screen, the length of the tube is smaller than 1.5 times the effective diameter of the entrance screen.
