ABSTRACT:
Via the shape of the photocathode surface and the geometry and potential distribution of electrodes of the electron-optical system, an X-ray image intensifier tube is optimized for reduction of the transit time variance for photoelectrons from the photocathode surface to a photoelectron detector. The photoelectron detector, on which an image need not be formed in this case, has, for example, a comparatively small entrance surface and is arranged in or near a cross-over of the photoelectrons.
