Abstract
An X-ray target assembly includes a cylindrical base and a cylindrical multilayered X-ray target that includes at least a heat transfer layer, an X-ray source layer and an adhesion layer provided between the heat transfer layer and the X-ray source layer, wherein the X-ray target is oriented such that the heat transfer layer is closest to the base, wherein the X-ray target is placed on top of a cylindrical carrying element, wherein the in-plane coefficient of thermal expansion of each of the heat transfer layer, the X-ray source layer, the adhesion layer and of the material of the carrying element is different, wherein the in-plane coefficient of thermal expansion of the heat transfer layer is the lowest and that of the material of the carrying element the highest.
