A gas-filled position-sensitive proportional counter was constructed for the detection and analysis of x rays in the 8--20 keV range. The detector's active volume is 9.5[times]3[times]0.4 cm[sup 3]. Based on an earlier design, the cathode incorporates a 160-ns delay line, etched using printed-circuit techniques. The detector operates at an 80-psig gas pressure and achieves a spatial resolution as low as 80 [mu]m and linearity better than 25 [mu]m. The counting efficiency ranges from 80% at 8 keV to 37% at 20 keV. The new detector allowed efficient recording of high-resolution spectra of the [ital K] emission lines from heliumlike Ge[sup 30+] and Kr[sup 34+].
