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.

X-ray target element is comprised of a planar wafer. The planar wafer element includes a target layer and a substrate layer. The target layer is comprised of an element having a relatively high atomic number and the substrate layer is comprised of diamond. The substrate layer is configured to support the target layer and facilitate transfer of thermal energy away from the target layer.

The present disclosure provides an X-ray tube device and a spring pin for an X-ray tube device. In an embodiment, the X-ray tube device includes: an outer cylinder assembly having an anode end and a cathode end, an anode end cap assembly provided at the anode end of the outer cylinder assembly and including an X-ray tube, a cathode end cap assembly provided at the cathode end of the outer cylinder assembly and including a high voltage receptacle for an external power supply, and a spring pin connection assembly provided in the outer cylinder assembly and connecting a filament lead of the X-ray tube to the high voltage receptacle.

A shield around an x-ray tube, a voltage multiplier, or both can improve the manufacturing process by allowing testing earlier in the process and by providing a holder for liquid potting material. The shield can also improve voltage standoff. A shielded x-ray tube can be electrically coupled to a shielded power supply.
