High Brilliance Beamline for Time Resolved X-ray Absorption Spectroscopy at ESRF

Abstract

Beamline 8 at the ESRF equipped with a low K undulator, coupling x-ray optics and an energy dispersive XAFS spectrometer is under construction and shall be in operation by 1995. Undulator gap tuning and tapering the magnetic field by a linear variation of the undulator gap will be provided to choose the spectral characteristics for experiments at defined absorption edges. A flux of 10 12 photons per second on the sample within the total spectral range of 5 keV to 25 keV and a time resolution below 100 microseconds shall be reached. Small sample volumes can also be analyzed due to the high brilliance of the generated synchrotron radiation.
