摘要： An x-ray tube for emitting x-rays which includes an anode and a cathode is disclosed herein. The x-ray tube includes a housing, an anode disposed in the housing and including a target, a cathode disposed in the housing at a distance from the anode, and a heat pipe thermally coupled to the cathode and extending away from the electron emitter. The cathode includes an electron emitter which is configured to emit electrons which hit the target of the anode and produce x-rays. The heat pipe provides transfer of thermal energy away from the electron emitter and into a heat sink.

摘要： A gas turbine engine component is disclosed having a cooling fluid passageway that provides relatively cool fluid to a surface of the gas turbine engine component. The cooling fluid passageway can be shaped in cross section to reduce a stress present in the gas turbine engine component. One form of the shape is non-circular. The gas turbine engine component can be formed such that an overhanging material otherwise formed by the intersection of a cooling fluid passageway and a surface of the gas turbine engine component is absent. The gas turbine engine component can also have a depression formed near the surface of the gas turbine engine component such that the cooling fluid passageway exits into an upstream portion and a downstream portion of the depression.

摘要： A thermal energy storage and transfer assembly is disclosed for use in electron beam generating devices that generate residual energy. The residual energy comprises radiant thermal energy and kinetic energy of back scattered electrons. The thermal energy storage and transfer assembly absorbs and stores an amount of the residual energy to reduce the heat load on other components in the electron beam generating device. The thermal energy storage and transfer device comprises a body portion of a sufficient thermal capacity to permit the rate of transfer of the amount of the residual energy absorbed into the assembly to substantially exceed the rate of transfer of the amount of the residual energy out of the assembly. The assembly also comprises a heat exchange chamber filled with a circulating fluid that transfers the thermal energy out of the assembly. Additionally, in an x-ray generating device, an x-ray transmissive filter suitable for absorbing residual energy is positioned between the anode and an x-ray transmissive window. The filter reduces the exposure of the window to the residual energy. The filter may additionally comprise a coating layer that further reduces the exposure of the window to the residual energy.

摘要： In an X-ray tube having a housing, an outer frame for providing a vacuum, a cathode mounted in the outer frame to project a stream of electrons, and an anode disposed to receive the electron stream at a focal spot position to produce X-rays, apparatus is provided for selectively mounting the anode within the housing. More particularly, the apparatus is disposed to respond to the heat generated by the X-ray production process to provide compensation for undesirable effects resulting from thermal expansion of the anode. The apparatus generally comprises an anode frame structure disposed to support the anode for rotation about a specified axis, and further comprises an anode plate joined to the frame structure for locating the anode at an initial position, in spaced-apart relationship with the cathode and with the aperture of a collimator in fixed relation to the tube, and for displacing the anode away from the initial position, in a direction opposite to the direction of anode thermal expansion, to provide compensation therefor. A compliant plate mounting arrangement is provided for selectively attaching the anode plate to the housing.

摘要： A brazed X-ray target includes a metallic cap and a graphite back including a nonlinear record groove attached thereto along a stepped surface. An upper corner joint of the stepped surface is distanced from a cap outer edge and a focal track where the maximum heat is generated during use of the target. The graphite back is extended outward toward the cap outer edge to increase a thermal storage of the graphite, and a recess is formed into the cap to maintain a selected moment of inertia of the target and thereby maintain the rotordynamics of a given X-ray tube.

摘要： A method of balancing X-ray anodes wherein the anode rotor is dynamically balanced separately from the anode target, the anode target is then attached to the anode rotor to provide the assembled anode, and the assembled anode is then dynamically balanced. This sequential balancing method has the advantage that it results in an anode which remains balanced during operation at speeds up to and exceeding the anode's critical speeds, even though the dynamic balancing steps may be performed at speeds substantially below the anode's critical speeds. This is also convenient because at such low balancing speeds, the dynamic balancing steps can be performed in air rather than vacuum without concern for oxidation and spalling of the rotor bearings, excessive vibration, and potential safety concerns.
摘要翻译：一种平衡X射线阳极的方法，其中阳极转子与阳极靶分开动态平衡，然后将阳极靶连接到阳极转子以提供组装的阳极，然后组装的阳极被动态平衡。这种顺序平衡方法具有的优点是，即使动态平衡步骤可以以低于阳极的临界速度的速度执行，其导致阳极在运行期间在高于和超过阳极的临界速度的速度下保持平衡。这也很方便，因为在这样低的平衡速度下，动态平衡步骤可以在空气而不是真空中进行，而不用担心转子轴承的氧化和剥落，过度的振动和潜在的安全性问题。
