A soft/hard x-ray beamline for surface EXAFS studies in the energy range 0.8–15 keV

Abstract

A new ultrahigh-vacuum x-ray beamline for surface EXAFS experiments has been constructed at the 2.5-GeV storage ring at Brookhaven National Laboratory, USA. Its design minimizes or eliminates a variety of problems inherent in other beamlines, providing state-of-the-art intensity, brightness, resolution, and beam stability over an extremely wide range of energy. Performance is discussed with initial results obtained after the recent x-ray ring shutdown.
