Abstract

An x-ray tube target includes an annular disk having an outer surface including front and back opposite faces, and an annular focal track fixedly joined to the disk front face for producing x-rays. The disk outer surface is rough away from the focal track, with surface roughness pits having width and depth dimensions greater than a wavelength of peak radiant emission of the target at operating temperature for increasing emissivity of the target to increase thermal radiation cooling thereof.
