SPOT-TYPE HIGH-INTENSITY X-RAY SOURCE

摘要

The present invention relates to X-ray sources having radiation areas with reduced effective dimensions. This invention can be used in X-ray microscopes, in microdefectoscopes as well as in X-ray tomographs. The device of the present invention includes an electron emitter (7), electronic focalisation lenses (9, 10) as well as a shooting-through anode (11), wherein said anode can be arranged in the window of the radiation source and may be provided with a cooling system (17). The electron beam is focused in the shape of a spot or a line behind the anode and along its trajectory. The iris (16) of the X-ray beam diaphragm (15) is provided at the focus of the electronic lens (10).
