摘要： An x-ray tube for emitting x-rays through an x-ray transmissive window is disclosed herein. The x-ray tube includes a casing, an x-ray tube insert which generates x-rays, an x-ray transmissive window disposed in the x-ray tube insert, and at least one heat pipe thermally coupled to the x-ray transmissive window. The x-ray transmissive window provides an area through which the x-rays pass. The heat pipe transfers thermal energy away from the x-ray transmissive window, providing intense, localized cooling of the x-ray window.

摘要： An X-ray tube device and a method for construction thereof which provides the cathode assembly and the anode assembly in a nose of the X-ray tube, wherein an emitter face of each assembly is directed toward an X-ray emission end thereof. The electrons emitted from the cathode assembly travel along a path outward until striking the anode assembly which then generates the X-rays which are directed toward a beryllium window in the X-ray tube. This advantageous structure enables the anode-to-window distance to be small, resulting in a large X-ray flux towards a sample. Furthermore, the small nose of the X-ray tube enables a fluorescence detector to be positioned in an optimal location because the X-ray tube's shape does not displace the fluorescence detector.
摘要翻译：一种X射线管装置及其构造方法，其将阴极组件和阳极组件提供在X射线管的鼻部中，其中每个组件的发射极面朝向其X射线发射端。从阴极组件发射的电子沿向外的路径行进，直到撞击阳极组件，然后该阳极组件产生朝向X射线管中的铍窗口的X射线。这种有利的结构使阳极与窗口的距离变小，导致朝向样品的X射线通量较大。此外，由于X射线管的形状不会使荧光检测器移位，因此X射线管的小鼻子使得荧光检测器能够位于最佳位置。

摘要： A rotating anode for x-ray generation uses a heat pipe principle with a heat pipe coolant located in a sealed chamber of a rotating portion of the anode. The rotating portion is positioned relative to a second portion so that relative rotation occurs between the two portions and so that a fluid path exists between the two portions through which an external cooling fluid may flow. The relative motion between the two portions provides a turbulent flow to the cooling fluid. The anode may also include cooling fins that extend into the sealed chamber. The sealed chamber may be under vacuum, and may be sealed by o-rings or by brazing. A closable fill port may be provided via which heat pipe coolant may be added. A balancing mass may be used to balance the anode in two dimensions.

摘要： A cooling system (300) for use with high-power x-ray tubes (200). The cooling system (300) includes a dielectric coolant (304) disposed in the x-ray tube housing (202) so as to absorb heat dissipated by the stator (400) and other electrical components, as well as absorbing some heat from the x-ray tube itself. To improve heat absorption from the stator (400) and the x-ray tube (200), the dielectric coolant (304) is circulated throughout the housing by a circulating pump (306). The cooling system also includes a coolant circuit employing a pressurized water/glycol solution as a coolant (314). Pressurization of the water/glycol solution is achieved by way of an accumulator (500) which, by pressurizing the coolant (314) to a desired level, raises its boiling point and capacity to absorb heat. A coolant pump (308) circulates the pressurized coolant (314) through a fluid passageway (216) defined in an aperture (206) of the x-ray tube (200) and through a target cooling block (302) disposed proximate to the x-ray tube (200) in the y-ray tube housing (202), so as to position the coolant to absorb some of the heat generated at the aperture (206) by secondary electrons, and the heat generatd in the target cooling block (302) by the target anode (210) of the x-ray tube (200). The target cooling block (302) is in contact with the dielectric fluid (304) so that some of the heat absorbed by the dielectric coolant (304) is transferred to the coolant (314) flowing through the target cooling block (302). The heated coolant is then passed through an air/water radiator (310) where a flow of air serves to remove some heat from the coolant (314). Thus cooled, the coolant then exits the radiator (310) to repeat the cycle.
