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.

摘要： A radiation generator may include an elongate generator housing having a proximal end and a distal end, a target electrode within the housing at the distal end thereof, a charged particle source within the housing at the proximal end thereof to direct charged particles at the target based upon a first biasing potential, and a field shaping electrode within the housing and adjacent the source to shape a field within the housing. At least one accelerator electrode may be within the housing on an opposite side of the field shaping electrode from the source to accelerate charged particles from the source to the target based upon a second biasing potential different than the first biasing potential. The field shaping electrode may be electrically floating so that the charged particles are directed from the source to the target without applying a biasing potential to the field shaping electrode.

摘要： In an X-ray radiation source, a counter wall made of alkali-containing glass, out of walls of a housing of an X-ray tube, is arranged opposite to a high-voltage region VH of a power supply unit including a high-voltage generation module which generates a negative high voltage to be applied to a filament. This configuration prevents an electric field from being generated in the counter wall and thus suppresses precipitation of alkali ions from the glass. Therefore, it prevents change in potential relationship between electrodes at different potentials such as the filament, grid, and target and prevents occurrence of a trouble of failure in maintaining a desired X-ray amount, thus enabling stable operation to be maintained.
