The invention relates to an x-ray anode and a process for its manufacture. The x-ray anode is characterized in that the anode material is embodied as a layer on a diamond window. The x-ray anode is preferably used with x-ray units which require as selective as possible x-radiation production to achieve as high as possible radiation intensity.

The microstructures may have any number of geometric shapes to best generate x-rays of high brightness and efficiently disperse heat.In some embodiments, the target comprising microstructures may be incorporated into a rotating anode geometry, to enhance x-ray generation in such systems.
