    Abstract: Liquid metal containment in an x-ray tube. In one example embodiment, an x-ray tube anode assembly includes a shaft terminated by a head and an anode connected to an anode hub. The anode hub is at least partially surrounding the head of the shaft. The anode hub is configured to contain a volume of a liquid metal and to rotate around the stationary shaft. The anode hub may also define a catch space within the anode hub that is configured to catch the liquid metal in order to contain the liquid metal within the hub while in a non-rotating state and regardless of the orientation of the x-ray tube anode assembly.

    Abstract: An x-ray device has a cathode aligned on a target region in a tube housing with a rotating anode unit. The rotating anode unit is borne to rotate around a rotational axis inside the tube housing. The rotating anode unit has a rotating anode plate with the target region and a shaft rotationally connected with the rotating anode plate. A magnetic bearing supports the shaft without contact in the tube housing. The rotating anode plate has an axial extension facing away from the shaft. The axial extension dips into a fluid-filled receptacle space of the tube housing for heat dissipation. Such an x-ray device allows high rotation speeds of the rotating anode unit, and thus a high operational power.

    Abstract: A shield structure is provided that is suitable for use in connection with an x-ray device that includes an anode and cathode disposed in a vacuum enclosure in a spaced apart arrangement so that a target surface of the anode is positioned to receive electrons emitted by the cathode. The shield structure is configured to be interposed between the anode and the cathode and includes an interior surface that defines an aperture through which the electrons are passed from the cathode to the target surface of the anode. Additionally, the aperture includes an inlet and an outlet sized so that the area of the inlet is relatively smaller than the area of the outlet. Finally, the shield structure is situated in the x-ray device such that the inlet of the aperture is positioned near the cathode and the outlet of the aperture is positioned near the anode target surface.

    Abstract: An x-ray tube 10 is provided including an anode mounted to a rotatable shaft positioned within a center bore of a stem element, a bearing assembly positioned between the rotatable shaft and the stem element, and at least one liquid metal shunt in thermal communication with both the rotatable shaft and the stem element, located adjacent to the anode between the anode and the bearing assembly, and directing heat generated at the anode away from the bearing assembly by allowing heat to flow from the rotatable shaft into the stem element prior to heat reaching the bearing assembly.

    Abstract: A high energy x-ray tube includes an evacuated chamber (12) containing a rotor (34) which rotates an anode (10) in the path of a stream of electrons (A) to generate an x-rays (B) and heat. The rotor includes a bearing shaft (54, 80, 122) connected to the anode by a thermally conductive structure (40). The bearing shaft carries soft metal-lubricated bearing balls (44F, 44R) in forward and rear bearing races (64, 66, 106, 108, 128, 130). An annular groove (70, 94, 132) is defined longitudinally in the shaft which, particularly when evacuated, provides a thermal barrier between the forward race and the portion of the shaft that is thermally connected with the anode. The groove lengthens the path heat entering the bearing shaft travels in order to reach the forward bearing race. As a result, the temperature of the forward race, and hence the evaporation of lubricant during operation of the x-ray tube, is reduced. The groove may be formed by electrical discharge machining the bearing shaft or by forming the shaft from inner and peripheral components (124, 126) which are connected together adjacent the rear bearing race (130).

    Abstract translation: 高能X射线管包括：真空室（12），其包含使电子（A）的路径中的阳极（10）旋转以产生X射线（B）和热量的转子（34）。 转子包括通过导热结构（40）连接到阳极的轴承轴（54,80，122）。 轴承轴在前后轴承座（64,66,106,108,128,130）中承载软金属润滑轴承滚珠（44F，44R）。 在轴上纵向地限定环形槽（70,94,132），特别是在抽空时，在前座圈和轴的与阳极热连接的部分之间提供热障碍。 凹槽延长进入轴承轴的路径，以便到达正向轴承座圈。 结果，在X射线管的操作期间，正向的温度和润滑剂的蒸发减少。 凹槽可以通过对轴承轴进行放电加工或者通过从邻近后轴承座圈（130）连接在一起的内部和外围部件（124,126）形成轴而形成。
