Latest Patents
Fraser holds a patent titled "Method and apparatus for prolonging the life of an X-ray target." This invention involves an X-ray generator that comprises an evacuated and sealed X-ray tube, which contains an electron gun and an X-ray target. The electron gun produces an electron beam with a cathode at negative high voltage. The design includes a filament positioned just inside the aperture of a Wehnelt grid, which is negatively biased relative to the filament. The system employs two sets of beam deflection coils mounted between the anode of the electron gun and the focusing lens to center the beam effectively. Additionally, an air-cored quadrupole magnet is situated between the focusing lens and the target, functioning as a stigmator that transforms the circular cross-section of the beam into an elongated one. This quadrupole can be rotated about the tube axis to adjust the orientation of the line focus, allowing for precise movement of the beam across the target surface by controlling the currents in the four coils of the quadrupole.
