Abstract: An object of the invention is to provide an X-ray generator having a simple configuration where heat generated in the irradiation window can be prevented from conducting to a desired portion in accordance with the purpose of use, the method of use or the structure of the X-ray tube. In an X-ray generator for releasing X-rays generated by irradiating a target placed in a vacuumed atmosphere within an X-ray tube with an electron beam from an electron source through an irradiation window of the X-ray tube, the irradiation window has thermal anisotropy where the thermal conductivity is different between the direction in which the irradiation window spreads and the direction of the thickness of the irradiation window, and therefore, the thermal conductivity in the direction in which the heat from the irradiation window is desired not to conduct is made relatively smaller.

Abstract: An x-ray radiator has an x-ray tube with a vacuum housing arranged in a radiator housing in which a coolant circulates. The vacuum housing has a porous coating, at least at parts thereof, on surfaces facing the coolant. The heat transfer between the vacuum housing and the coolant is thereby improved, such that the x-ray radiator can be more highly thermally loaded.
