摘要： 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.

The vacuum envelope has a first metal member connected to the anode target, a second metal member which is connected to the first metal member and has a coefficient of thermal expansion lower than that of the first metal member, and an electrically insulating annular ceramic member connected to the second metal member and the cathode. In addition, the X-ray tube has a cooling system which is connected to the first metal member and forms a cooling passage. Furthermore, the X-ray tube has an adapter which is in contact with the first metal member, surrounds the second metal member and has a thermal conductivity higher than that of the second metal member, and a heat-transfer medium placed between the ceramic member and the adapter.

摘要： Conventionally, the magnetic field generator was arranged perpendicularly to the axis of the electron beam. The magnetic field generator of this invention is arranged so as to be inclined relative to the plane perpendicular to the axis of the electron beam. Specifically, the magnetic field generator is arranged so as to be inclined relative to the plane perpendicular to the axis of the electron beam within the range in the cathode side from the focused and deflected electron beam. Inclination up to the anode side opposite to the cathode side will lead to a possibility of increasing the reduced X-ray source diameter. Thus, arranging the magnetic field generator so as to be inclined within the range in the cathode side from the electron beam may reduce the X-ray source diameter.
摘要翻译：通常，磁场发生器垂直于电子束的轴线布置。本发明的磁场发生器被布置成相对于垂直于电子束轴的平面倾斜。具体地说，磁场发生器被布置为相对于垂直于电子束轴线的平面在从聚焦偏转电子束的阴极侧范围内倾斜。直到与阴极侧相反的阳极侧的倾斜将导致增加X射线源直径减小的可能性。因此，将磁场发生器设置成在电子束的阴极侧的范围内倾斜，可能降低X射线源直径。

摘要： An x-ray source has an evacuated tube. An anode is disposed in the tube and includes a material configured to produce x-rays in response to impact of electrons. A cathode is disposed in the tube opposing the anode configured to produce electrons accelerated towards the anode in response to an electric field between the anode and the cathode. A flange extends from the cathode toward the anode, and has a smaller diameter than the evacuated tube. The flange extends closer to the anode than an interface between the cathode and the tube thus forming a reduced-field region between the evacuated tube and the flange.

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.
