Gas proportional counters (GPCs) are well suited for fluorescence extended x-ray-absorption fine structure (EXAFS) experiments in the soft x-ray (〈4 keV) region. They have a near unity detection efficiency and offer good energy resolution. Of the different types of GPC, the parallel-plate device is an attractive option for use with synchrotron radiation beam lines where its intrinsically high count rate permits optimum use of the high photon flux available. The development of a parallel-plate gas proportional counter for use on soft x-ray beam lines at the Daresbury synchrotron source is described. This device is demonstrated to have a counting rate in excess of 1 MHz, and data are presented on its performance including its energy resolution, long-term gain stability, and sample EXAFS spectra.
