ABSTRACT:
Filter apparatus for use in x-ray equipment including a repetitively pulsed x-ray source, a window for transmitting x-rays generated by the source to an object to be irradiated, and a vacuum chamber containing the x-ray source and the filter apparatus. The filter apparatus includes a baffle for diffusing hot gases and directing them away from the window. The filter apparatus further includes an ultraviolet light absorber which overlies the window with respect to the x-ray source whereby undesirable components generated with the x-rays by the x-ray source are substantially eliminated prior to reaching the window. Also disclosed is a method of eliminating undersirable by-products of x-ray generation.
