Abstract: A target for x-ray tubes, which is comprised of separate elements mechanically connected together whereby the element which includes the x-ray generating focal area is of a selected material mechanically attached to at least one element of a second material by means which efficiently permits ready transfer of heat from the first element to the second while permitting free thermal expansion of the elements relative to one another.

Abstract: An X-ray tube including a target structure having a focal area for receiving electrons from an adjacent cathode and generating X-radiation in response thereto, the focal area being provided with a surface designed to improve thermal properties such as by covering with a closely packed wrapping of relatively fine wire, the focal area preferably being a wire-wrapped annulus sandwiched between two discs of high thermal conductivity material.

Abstract: An X-ray generating system comprising an X-ray tube having an electron-emitting cathode disposed in spaced opposing relationship with an anode target surface and supported within a focusing cup which is provided with means for directing emitted electrons into a Gaussian distribution pattern on the target surface, such that the area of the resulting focal spot is minimized and useful X-rays radiate therefrom in a corresponding Gaussian distribution pattern.
