✦ Synopsis

Performance characteristics of a microstrip gas counter operated as an x-ray Ñuorescence spectrometer are reported. Gas ampliÐcation as a function of microstrip anode-cathode voltage was measured, and the breakdown threshold voltage was determined in pure xenon. The detector temporal stability and the e †ect of gas purity were assessed. Energy resolution and linearity, detection efficiency and uniformity of spatial response in the 2-60 keV x-ray energy range were determined from the pulse-height distributions of the Ñuorescence x-ray spectra induced in a variety of single-and multi-element sample materials. Energy resolution similar to that of conventional proportional counters was achieved at 6 keV.
