摘要： An x-ray tube includes an anode comprising a focal track and a cathode assembly configured to emit an electron beam toward a focal spot on the focal track. The x-ray tube also includes a controller configured to wobble the electron beam among a plurality of focal points in a direction tangent to the focal track. The plurality of focal points includes at least one focal point that is bounded by a pair of boundary focal points. The controller is further configured to delay a wobble of the electron beam away from the at least one focal point for a pre-determined amount of time.

摘要： A structure for collecting scattered electrons within a substantially evacuated vessel containing both an electron-emitting cathode and an electron-attracting anode is disclosed herein. The electron-collecting structure includes a two-sided first plate, a two-sided second plate, a fluid inlet, and a fluid outlet. The first plate is both electrically conductive and thermally emissive and is mountable within the vessel so that its first side at least partially faces the anode. The second plate is also thermally emissive and has a first side that is substantially conterminous with the second side of the first plate. Furthermore, the second plate additionally has an internal conduit for conveying a heat-absorbing fluid within. Both the fluid inlet and the fluid outlet are in fluid communication with the conduit in the second plate. During operation, the structure is able to attract scattered electrons and transfer thermal energy attributable to the electrons away from the structure.
摘要翻译：本文公开了一种在包含电子发射阴极和吸电子阳极的基本抽空的容器内收集散射电子的结构。电子收集结构包括双面第一板，双面第二板，流体入口和流体出口。第一板是导电和热发射的，并且可安装在容器内，使得其第一侧至少部分地面对阳极。第二板也是热发射的，并且具有与第一板的第二侧基本相连的第一侧。此外，第二板还具有用于在其内输送吸热流体的内部导管。流体入口和流体出口都与第二板中的导管流体连通。在运行期间，该结构能够吸引散射的电子并将归因于电子的热能转移到结构之外。

摘要： An x-ray tube window cooling assembly (11) for an x-ray tube (18) includes an electron collector body (110). The electron collector body (110) is thermally coupled to an x-ray tube window (102). The electron collector body (110) may include a coolant circuit (112) with a coolant inlet (114) and a coolant outlet (122). One or more thermal exchange devices may be coupled to the x-ray tube window (102) or to the coolant circuit (112) and reduce temperature of the x-ray tube window (102).
