Abstract:
1. An x-ray source for producing a uniformly intense area x-ray beam, comprising: a vacuum chamber; an area electron emitter disposed at a first end of the vacuum chamber and including an electron emitting surface; a target material disposed at a second end of the vacuum chamber and spaced apart from the area electron emitter, the target material including an x-ray emitting surface facing the electron emitting surface, wherein the target material is a shaped anode, the shaped anode being curved and one of concave, convex, concavoconcave, concavoconvex, and convexoconvex; the electron emitting surface and the x-ray emitting surface are correspondingly curved; and at least one high voltage power source, the area electron emitter electrically connected to a negative pole of one of the at least one high voltage power source and the target electrically connected to a positive pole of one of the at least one high voltage power source.
