VESPERS:
Very sensitive Elemental and Structural Probe Employing Radiation from a Synchrotron
VESPERS is a hard X-ray microprobe beamline 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, as well as X-ray absorption spectroscopy. Multi-bandpass and pink beam capability are built in to meet various requirements. A mm-sized beam is also available for the experiments.
* Call for Proposals Cycle 43 (Jan-June 2027): Open Now, by Aug 19 noon, 2026.
* Current status: Cycle 42 - Normal operation. Planned shutdown between Aug 31 - Oct 26.
