Abstract

The microcalorimeter energy dispersive x-ray spectrometer, the silicon drift detector (SDD), and polycapillary x-ray optics are recent developments that have significantly advanced analytical x-ray spectrometry for electron beam instruments. The microcalorimeter EDS is capable of high resolution operation (approximately 5 eV wide peaks) over a wide range of photon energies (250 eV 10 keV). The microcalorimeter EDS can be successfully applied to peak interference problems that are not accessible with the conventional semiconductor EDS such as TiN and BaTiO3. Polycapillary x-ray optics can augment the collection angle of the microcalorimeter EDS to increase its sensitivity. The SDD is capable of extremely high count rates, up to 1 MHz, and is especially useful for high speed x-ray mapping.
