A high-power and high-flux X-ray wiggler station at the Cornell high energy synchrotron source

Abstract

The F2 wiggler station at The Cornell High Energy Synchrotron Source has been in operation since August of 1990. This versatile stationis designed to accommodate a wide variety of state-of-the-art synchrotron experiments. The station can produce tunable doubly-focused monochromatic radiation as well as unfocused white beam. Macromolecular crystallography experiments using multiple wavelength anomalous diffraction (MAD) and high resolution diffraction experiments have taken advantage of the high flux, high energy resolution, and the tunability of the station in the monochromatic mode; nano-eV spectroscopy experiments using nuclear resonant scattering have utilized the high flux available at a particular energy; and high heat load tests of X-ray optics have used the full power of the white beam. In this article we present several key elements of the station design and review the X-ray beam characteristics as they pertain to the scientific work done at F2 during the past few years.
