摘要： A mechanism for cooling the anode of an x-ray tube using a phase change material to transfer heat away from the anode. The x-ray tube is joined to a sealed heat exchange chamber which contains a liquid metal as a liquid to vapor phase change material (L-V PCM). The back side of the anode is exposed to an interior of the heat exchange chamber, and a jet sprayer inside the heat exchange chamber sprays a liquid of the metal onto the back side of the heated anode. The L-C PCM evaporates on that surface to carry away the heat, and the vapor then condenses back into the liquid on the cool surfaces of the heat exchange chamber. The surfaces of the heat exchange chamber may be cooled by convection cooling. Optionally, pipes containing a circulating cooling fluid may be provide inside the heat exchange chamber.

摘要： There is provided an anode stack for cooling and electrically insulating a high voltage anode of an X-ray device. The anode stack has at least a conductor member and a dielectric member, and the conductor member has a main body and a peripheral portion. The dielectric member overlies and couples with the main body of the conductor member at one surface. At an opposing surface of the main body of the conductor member, an end of the high voltage anode is coupled thereto in use. The peripheral portion of the conductor member has an annular region that surrounds at least a part of the dielectric member and which is spaced therefrom.

摘要： The invention relates to a metal jet x-ray tube which is less affected by the problem of the power density at the point of impact of the electron beam on the anode component than conventional tubes. For this purpose the metal jet x-ray tube has a metal jet (6) as anode component (7), which metal jet is so thin that an electron beam (4) impinging on the metal jet (6) is only partially decelerated by the metal jet. Furthermore a blade cathode is provided as a cathode component (3), which blade cathode comprises a cathode blade (10) directed with a slight inclination downwards in the direction of the liquid metal jet (6) of the anode component (7).
