Abstract
A method and apparatus for providing a window frame and window for use in an x-ray tube, wherein the new structure reduces deforming stresses on the window produced by pressure differential incident upon the window. The support structure of the window frame to which the window is attached is angled toward the interior of the x-ray tube to an angle equaling the deflection to which a window is typically subjected in standard window frames. A window mounted to a frame in accordance with the present invention is subjected to reduced or eliminated deforming stresses, even in high deflection stress environments including air bake x-ray tube manufacturing processes. This elimination of deforming stresses allows for the use of thinner x-ray tube windows enabling a higher transmissivity of produced x-rays.
