    Abstract: Provided are an X-ray tube device and an X-ray CT apparatus, which are capable of improving cooling efficiency of a stator coil together with cooling efficiency of an X-ray window.
    An X-ray tube device includes an X-ray tube including an envelope that holds, in a vacuum, a cathode generating an electron beam and an anode emitting an X-ray by collision of the electron beam, and an X-ray window through which the X-ray is transmitted; a stator coil configured to generate a driving force for rotating the anode; a tube container configured to accommodate the X-ray tube and the stator coil together with insulating oil; and a cooler configured to cool the insulating oil, in which the X-ray tube device further includes a first inflow port connected to a pipe linking the tube container and the cooler and disposed near the X-ray window, a second inflow port connected to the pipe and disposed near the stator coil, and a controller configured to cause the insulating oil to flow into the tube container through the first inflow port in a case where the X-ray is emitted and to cause the insulating oil to flow into the tube container through the second inflow port in a case where the X-ray is not emitted.

    Abstract: Presented systems and methods facilitate efficient and effective generation and delivery of radiation. A radiation generation system can comprise: a particle beam gun, a high energy dissipation anode target (HEDAT); and a liquid anode control component. In some embodiments, the particle beam gun generates an electron beam. The HEDAT includes a solid anode portion (HEDAT-SAP) and a liquid anode portion (HEDAT-LAP) that are configured to receive the electron beam, absorb energy from the electron beam, generate a radiation beam, and dissipate heat. The radiation beam can include photons that can have radiation characteristics (e.g., X-ray wavelength, ionizing capability, etc.). The liquid anode control component can control a liquid anode flow to the HEDAT. The HEDAT-SAP and HEDAT-LAP can cooperatively operate in radiation generation and their configuration can be selected based upon contribution of respective HEDAT-SAP and the HEDAT-LAP characteristics to radiation generation.

    Abstract: 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.
