Development of a Self-Contained Portable Unit for Nondestructive Compositional Analysis of Aircraft and Space Systems Alloys.

Abstract

Two portable radioisotope excited X-ray fluorescence systems have been designed and delivered, one a high resolution type using a cryogenically cooled solid state detector and the other a gas filled proportional counter operated in conjunction with balanced x-ray filters. The measurement probes were designed for sample areas that may be of small size or that may occur in recessed locations. Measurement techniques were formulated and studied that use pure elemental standards in conjunction with just a single alloy reference for a given unknown. Computational programs were written to implement these techniques. A set of twenty-seven analyzed reference alloys was also provided. This report summarizes the design aspects of the two systems and the course of evaluation of the measurement techniques. (Author)
