Abstract
An anode assembly for generating x-rays has a mounting block with a channel therethrough, with a diamond wafer mounted sealingly across an opening in the block so as to have an inner surface in contact with the coolant flowing in the channel. Alternatively, a thicker diamond member is mounted in the block with thermal conduction through the metal block. A metal anode film bonded to the outer surface of the diamond is receptive of a focused electron beam to generate x-rays. The diamond provides cooling in compensation for the film being heated by the electron beam. The assembly is useful in a scanning x-ray monochromator instrument for chemical analysis of a specimen surface.
