“…The combination of the imaging optic with the spatial and energy resolution of the CCD makes possible an imaging x-ray fluorescence spectrometer ͑IXRFS͒ that can produce elemental maps with submillimeter resolution but with no moving parts. 1,2 Both the MCP and x-ray CCD detector technologies have been developed primarily for applications in x-ray astronomy and planetary science. 3,4 The IXRFS is in fact scale invariant; replacing the lab x-ray source by the solar corona and the lab sample by the surface of an airless inner solar system body, one has a remote sensing instrument for mapping the surface compositions of the planets.…”

A new form of imaging x-ray fluorescence spectrometer, based on a microchannel plate relay optic and a charge coupled device x-ray detector, produces elemental mapping over an instantaneous field of view of 24 mm square without the need to scan either the sample or x-ray beam. We describe the design of a prototype responsive over the energy range of 370 eV-10 keV, its quantitative calibration, demonstration of 0.7 mm spatial resolution and the spectrometer's use in the analysis of geological samples.
