Abstract

We have developed a high-resolution energy-dispersive x-ray spectrometer (EDS) based on cryogenic microcalorimeter x-ray detectors for use in x-ray microanalysis. With an energy resolution of 3 eV at 1.5 keV, count rate of {approximately} 500 s-1, and an effective collection area of {approximately} 5 mm2 (using polycapillary x-ray optics), the microcalorimeter EDS combines many of the favorable qualities of commercially-available wavelength dispersive spectrometers (WDS) and semiconductor EDS. After describing the spectrometer system, we present several applications of microcalorimeter EDS to important microanalysis problems.
