Abstract
A rotating anode target for X-ray devices comprises a circular graphite disc structure both of whose front and back sides or faces taper equally towards each other and define a narrow rim surface and central hub section. A larger area of the front face is coated with a focal track metal which extends coextensively over the front face to overlap part of the rim surface. The slant height dimension of the focal track metal is greater than the diameter of the hub section.
