Abstract: The present invention relates to a high-voltage x-ray tube (R) with an inner vacuum chamber (11) in which lie, oriented opposite one another, a cathode (8) held at a negative high voltage during operating conditions and an anode (2) held at a positive high voltage during operating conditions, wherein the anode (2) is affixed to an anode isolation element (3a) such that the anode isolation element (3a) has a cylindrical form or a form tapering toward the anode (2) and comprises an opening (5a) to receive a high-voltage plug (12) and has a conductor structure (6/7) via which a coolant can be supplied to the anode (2). This coolant can be, in particular, an insulating oil or another electrically nonconductive liquid. The conductor structure (6/7) can, for example, be integrated completely into the interior of the anode isolation element (3a) but can also be integrated into the surface of the high-voltage plug (12). In another possible solution, the conductor structure (6/7) is integrated into an intermediate element (13) which lies between the anode isolation element (3a) and the high-voltage plug (12).

Abstract: A portable X-ray source device for producing a selected number of uniform X-ray output pulses. The device comprises a spiral capacitor voltage generator, a transformer assembly and a cold-cathode emitter X-ray tube. The capacitor and transformer are coaxially disposed in mating sections of a cylindrical canister which is evacuated and filled with oil. The tube is disposed centrally within the capacitor and transformer for packaging efficiency. Corona suppression means are provided for preventing high voltage damage within the canister. The X-ray tube employs an emitter comprising spaced rings of woven graphite material. A spark gap trigger device including tungsten electrode strips is mounted on the outside of the canister where it can occupy the corner space of a square sheet metal housing. A slide-in battery cartridge and high power converter circuit are provided for dc operation.
