Abstract
In an X-ray tube for an X-ray analysis apparatus an optimized minimum working distance is achieved, together with an adequately high radiation yield, by integrated optimization of the radiation end of the tube, the position and the mounting of the exit window, and the electron-optical configuration in the tube. This results in an X-ray tube having a conical end, an angle of cone of approximately 45.degree. and the use of the cone as such in the electron-optical system of the tube. Exact determination of the anode position relative to a reference face outside the tube enables exact positioning of each individual tube in an analysis apparatus.
