Abstract

The present invention is directed to a radiographic apparatus that utilizes a single integral housing for providing an evacuated envelope for an anode and cathode assembly. The integral housing provides sufficient radiation blocking and heat transfer characteristics such that an additional external housing is not required. The integral housing is air cooled, and thus does not utilize any coolant. In addition, the integral housing is insulated with a potting material, which electrically insulates the integral housing and its components, and also limits the amount of noise emitted from the housing during operation. In an alternative embodiment, enhanced thermal and electrically insulating properties are achieved through the use of a potting material disposed in selected areas of the tube interior. The potting material cooperates with optimized airflow through the tube assembly to effectively and continuously remove heat therefrom.
