The Scanning X-ray Fluorescence Microscopy (SFXM) capability at CHESS draws users from diverse fields, including Environmental Science, Soil Science, Anthropology and Native American Studies, Dendrochronology and Classics. When the author inherited responsibility for the F3 beamline, two of the elements essential for the success of this research program were already available: wide-bandpass multilayers to provide the intense monochromatic flux required for detection of elements in trace quantities; and singlebounce capillary x-ray optics capable of yielding microbeams at the sample position.
