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.

Filter apparatus for use with an x-ray source

A system for generating soft X rays. This system includes valve apparatus for repetitively providing bursts of a gas of brief duration and a magnetic pulse compression power supply for providing high current pulses. The system further includes a transmission line connected to the power supply for transmitting power pulses from the supply to discharge through bursts of gas. The power supply includes a plurality of series saturable inductor magnetic switches and a plurality of shunt capacitors. Thus, upon synchronized provision of a burst of gas from the valve apparatus and a power pulse from the power supply, a high current discharge generates plasma and an intense magnetic field which radially compresses the plasma, resulting in a dense, high temperature plasma which is an intense source of soft X rays.
