Rotary anode assembly for an X-ray source

Abstract

A rotary anode assembly for an X-ray source, having a annular V-groove target portion for generating a desired characteristic X-ray emission by an electron beam bombardment applied thereto, wherein the V-grooved target portion is formed from a pair of target members each being formed into a body of rotation with respect to the axis of rotation of the assembly and having a surface including therein a coaxially-formed annular tapered portion. The target members are combined together so that the annular tapered surface portions face to each other with a predetermined angle therebetween, thereby constituting the annular V-groove. The annular V-groove target portion is formed in the peripheral surface of the rotary anode assembly or in the side surface of the anode assembly, which is perpendicular to the axis of rotation. The V-groove target portion is cooled by fluid coolant circulated through the inner space between the target member and the corresponding associated supporting member having a plurality of channels provided for allowing the fluid coolant to be supplied to the space.
