Portable X-ray device

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.
