A high-voltage supply for an x-ray emitter, in particular to provide a cathode current and a cathode voltage, has at least two electrical conductors, which are incorporated in a common insulating body. Each electrical conductor is assigned a connector element, which is configured for electrically conducting contact with a corresponding connector of the x-ray emitter. Such a high-voltage supply for supplying the cathode voltage and the cathode current is provided in an x-ray emitter. The high-voltage supply extends at least in part over an inner region of a radiation protection housing of the x-ray emitter.

High-voltage supply and an x-ray emitter having the high-voltage supply

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 tube unit

A high-voltage plug for an X-ray tube plugs onto a high-voltage terminal provided at the vacuum housing of the X-ray tube. The high-voltage plug contains a cooling channel for a coolant. An improved are over protection results by use of the coolant.
