X-ray converging mirror for an energy-dispersive fluorescent X- ray system

摘要

An X-ray converging mirror that can be positioned adjacent an X- ray source for reflecting X-ray beams from the X-ray source includes an X-ray converging mirror having a reflecting surface of a cross- sectional profile expressed by a curve of the following equation:P P x=y tan . theta.[1-ln(y/b)]PPwherein x and y denote a coordinate system, . theta. is equal to or less than a Bragg critical angle of reflection for the X-ray beams, and b denotes a point on the y- axis when dx/dy is 0.
