Abstract

We describe the current performance of the prototype microcalorimeter energy-dispersive spectrometer (5cal EDS) developed at NIST for X-ray microanalysis. We show that the low-energy 5cal EDS, designed for operation in the energy range 0.2-2 keV, offers significant advantages for low-beam-energy microanalysis. We present several examples in which the prototype 5cal EDS has been used to solve problems in low-voltage microanalysis. Including the analysis of tungsten silicide (WSI₂), titanium nitride (TiN)and Barium titanate (BaTiO₃) and the measurement of chemical shifts in Fe and C compounds.
