Abstract: Apparatus for connecting an HV cable to the cathode of an X-ray tube is provided with a housing disposed for attachment to the X-ray tube, and a quantity of epoxy or other electric insulating material contained within the housing. The epoxy serves to insulate the exposed end portions of the HV cable conductors, which extend beyond the cable insulation for insertion into the X-ray tube casing. The connector apparatus further includes a heat transfer device, such as a heat pipe, which extends long the cable within the connector housing. A quantity of working fluid contained in the heat transfer device is disposed for bi-directional movement along the device to transfer heat from a first location within the insulating material to a second location proximate to the housing.

Abstract: An apparatus and method for determining the density and other properties of a formation surrounding a borehole using a high voltage x-ray generator. One embodiment comprises a stable compact x-ray generator capable of providing radiation with energy of 250 keV and higher while operating at temperatures equal to or greater than 125° C. In another embodiment, radiation is passed from an x-ray generator into the formation; reflected radiation is detected by a short spaced radiation detector and a long spaced radiation detector. The output of these detectors is then used to determine the density of the formation. In one embodiment, a reference radiation detector monitors a filtered radiation signal. The output of this detector is used to control at least one of the acceleration voltage and beam current of the x-ray generator.

One embodiment comprises a stable compact x-ray generator capable of providing radiation with energy of 260 keV and higher while operating at temperatures equal to or greater than 125° C. In another embodiment, radiation is passed from an x-ray generator into the formation; reflected radiation is detected by a short spaced radiation detector and a long spaced radiation detector. The output of these detectors is then used to determine the density of the formation. In one embodiment, a reference radiation detector monitors a filtered radiation signal.

Abstract: A high voltage connector assembly is disclosed for use with high power apparatus including x-ray devices. The present connector is a pancake-style connector, and interconnects a high voltage cable with the cathode of the x-ray tube. The present connector includes a housing, a socket assembly, and insulating material surrounding the socket assembly to insulate it from the housing. The socket assembly comprises a potting-filled conductive sleeve having a continuously shaped, smooth terminal end. The terminal end of the sleeve forms a triple junction with the insulating material and air present near the sleeve. The continuously smooth terminal sleeve end prevents electrical arcing to occur at the triple junction by reducing field strength at the terminal end and urging the electric field of the socket assembly away from the triple junction. The reduction in electrical arcing propensity allows the x-ray device to operate at relatively higher operating voltages.
