Abstract: An x-ray system includes x-ray tube containing a cathode which supplies electrons and an anode which can be maintained at high positive electrical potential to the cathode and has a target area which is impacted by electrons from the cathode when the positive potential is maintained generating x-rays. The x-ray tube is enclosed in a radiation resistant casing. The radiation resistant casing has a window which allows some of the x-rays generated at the target area to exit the system. The window has a vapor deposited layer of a filtering metal of sufficient thickness to effectively condition the x-rays passing through the window and located to intercept the x-rays passing through the window.

Abstract: An x-ray tube includes a frame enclosing a high vacuum, a cathode positioned within the enclosure, a bearing assembly a stationary component comprised of a first base substrate, the first base substrate having a first surface, a rotatable component comprised of a second base substrate, the second base substrate having a second surface, wherein the rotatable component is positioned proximate the stationary component such that a gap is formed between the first surface and the second surface, a liquid metal positioned within the gap, and an antiwetting coating attached to at least one of the first surface and the second surface, the coating includes titanium nitride attached to the at least one of the first surface and the second surface, and an oxide of titanium attached to the titanium nitride.

Abstract: An x-ray tube includes a housing enclosing a vacuum chamber, a cathode positioned within the vacuum chamber configured to emit electrons, and an anode positioned within the vacuum chamber to receive the electrons emitted from the cathode and generate a beam of x-rays from the electrons. The x-ray tube also includes a magnetic coupler drive configured to rotate the anode, with the magnetic coupler drive having an inner rotor frame positioned within the vacuum chamber and an outer rotor frame positioned outside the vacuum chamber and adjacent the inner rotor frame. The magnetic coupler drive also includes an inner rotor magnet mounted to the inner rotor frame and an outer rotor magnet mounted to the outer rotor frame. The inner and outer rotor magnets interact to generate a magnetic field that transfers torque from the outer rotor to the inner rotor, thereby causing the inner rotor to rotate the anode.

Abstract: The present disclosure provides for the application of a two-dimensional ultrasonic phased array (100), formed of a plurality of transducers (102) arranged in a rectilinear pattern, for material and volumetric component testing. The two-dimensional array enables electronic adjustment of the focal properties and size of the aperture in both the azimuthal and elevational directions such that uniform and/or specified sound field characteristics can be obtained at any or all locations in the component being tested.
