NASA 1998 SBIR Phase I


PROPOSAL NUMBER: 98-1 28.01-0930

PROJECT TITLE: An XRD/XRF Instrument for Microanalysis of Rocks and Minerals

TECHNICAL ABSTRACT (LIMIT 200 WORDS)

The proposed instrument will assist in the simultaneous chemical and mineralogic analysis of microsamples of soil, rocks and minerals by x-ray fluorescence and x-ray diffraction. The innovations include a compact, low-average power, high-peak power, microfocus x-ray source (tube) that uses a pulsed field emitter cathode (no thermionic emission) to produce a bright, x-ray microspot on the sample and an electronic array detector that records the diffracted x rays and the fluorescent x rays that are back scattered from the sample. The instrument's configuration allows flexibility in sample preparation-large samples as well as microsamples can be used without special preparation.

POTENTIAL COMMERCIAL APPLICATIONS

Commercial applications include: elemental identification, orienting crystals, examining axis wander in crystals, measuring grain size, measuring phase change in alloys as a function of time, measuring stress, etc.
