Abstract

A new soft X-ray (50-1500 eV) beamline has been constructed at a bending magnet station at the Photon Factory in order to perform photoemission spectroscopy (PES), X-ray absorption fine structure (XAFS), photoelectron diffraction (PED) and X-ray magnetic circular dichroism (XMCD) experiments in surface chemistry. Approximately 10¹¹ photons/s can be obtained with a medium resolution (E/ΔE∼1000), while E/ΔE∼8000 can be attained at the N K edge with a photon flux of ∼10⁹ photons/s. In addition to conventional XAFS, a novel technique 'energy dispersive NEXAFS (near-edge X-ray absorption fine structure)' has been successfully developed. The performance of the new beamline is reported and typical examples of its application to surface chemistry are demonstrated.
