Very Sensitive Elemental and Structural Probe Employing Radiation from a Synchrotron (VESPERS) 07B2-1


VESPERS is a hard X-ray microprobe capable of providing a high level of complementary structural and analytical information. The techniques of X-ray diffraction and X-ray fluorescence spectroscopy are employed to analyze a microscopic volume in the sample. Multi-bandpass and pink beam capability are built in to meet variable requirements.
