Abstract Recent advances in multielement solid-state detector systems for high rate, high resolution x-ray spectroscopy at noncryogenic temperatures will be described in this paper. A 16-channel silicon detector system, designed and built at BNL, has been recently operated in the NSLS machine beam {number_sign}X19A, showing an average energy resolution of less than 250 eV FWHM, which is adequate to discriminate the fluorescence trace element against the background of elastically scattered photons in a typical EXAFS application. A larger, 128 channel system, will soon permit a higher overall count rate: {approx_gt}10{sup 6} counts per second. It is shown that, in order to achieve high resolution with a solid-state detector, special care must be spent in the detector-preamplifier assembly. A low noise detectorpreamplifier may be obtained integrating the front-end devices (an FET and/or a feedback capacitor) with the detector itself. {copyright} {ital 1996 American Institute of Physics.}
