NEW HIGH-DISPERSION HIGH-RESOLUTION X-RAY SPECTROMETER

Abstract
A high-efficiency, high-resolution, high-dispersion, low-cost x-ray spectrometer is described. Although the instrument was developed primarily for space-science applications, it has a broad range of application for normal laboratory research problems. As an example of its performance, measurements of the CrKα1,2 spectrum are presented. The observed, uncorrected full-widths at half-maximum intensity are Kα1 = 2.09 eV and Kα2 = 2.67 eV. Fine structure details, hitherto unreported, were also observed.
