Abstract :
The performance of the first soft X-ray beamline BL25SU at SPring-8 is described. A grating monochromator is found to realize very good energy resolution. This is demonstrated by the experimental photoabsorption spectra of the Ar 2p(∼250 eV) and N2 1 s (∼400 eV) edges, which show the quality competitive to or better than the best results reported to date. In addition, the excellent performance is augmented by the high photon flux of about 1011 photons/s100 mA−10.02%−1 b.w., low degree of higher order light (less than 1%) and high circular polarization at the experimental stations.
