    Abstract: An x-ray tube unit includes an x-ray tube unit housing, in which a vacuum housing is disposed, which includes a high-voltage component. The vacuum housing includes an insulating medium circulating in the x-ray tube unit housing flowing around it. Further, a cathode module and an anode are disposed in the vacuum housing, the cathode module lying at high voltage and including an emitter which emits electrons when heating current is fed to it. In addition, a potential difference is present between the cathode module and the anode for accelerating the emitted electrons. In accordance with an embodiment of the invention a high-voltage feed, a heating transformer and a radiation protection component are integrated into the high-voltage component, the high-voltage component being filled at least partly with an electrically-insulating encapsulation material. This produces a compact and installation-friendly x-ray tube unit which has high operational safety.

    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: A cooling system for use with high-power x-ray tubes. The cooling system includes a dielectric coolant disposed in the x-ray tube housing so as to absorb heat dissipated by the stator and other electrical components, as well as absorbing some heat from the x-ray tube itself. The cooling system also includes a coolant circuit employing a pressurized water/glycol solution as a coolant. Pressurization of the water/glycol solution is achieved by way of an accumulator which, by pressurizing the coolant to a desired level, raises its boiling point and capacity to absorb heat. A coolant pump circulates the pressurized coolant through a fluid passageway defined in an aperture of the x-ray tube and through a target cooling block disposed proximate to the x-ray tube in the x-ray tube housing, so as to position the coolant to absorb some of the heat generated at the aperture by secondary electrons, and the heat generated in the target cooling block by the target anode of the x-ray tube. The target cooling block is in contact with the dielectric fluid so that some of the heat absorbed by the dielectric coolant is transferred to the coolant flowing through the target cooling block. The heated coolant is then passed through an air/water radiator where a flow of air serves to remove some heat from the coolant. Thus cooled, the coolant then exits the radiator to repeat the cycle.
