AbstractNot Available We propose to develop multi-channel silicon x-ray detector arrays, and their associated integrated circuit pulse-processing electronics, for high energy resolution remote x-ray fluorescence measurements for planetary geochemical analysis. The detectors will detect x-rays from planetary bodies, such as the moon, asteroids, comets and Mercury, which are produced by fluorescence from the solar x-ray flux. The detectors will be sensitive in the 1 - 20 keV energy range, will have 200-400 eV FWHM energy resolution, will cover an area 100-200 cm2, and will operate without mechanical or cryogenic cooling. The detectors will be designed using one-dimensional strips delineating the individual detector elements, but will be fabricated on single monolithic substrates. A detector
