Abstract
The performance of the first soft X-ray beamline BL25SU at SPring-8 is desc ribed. A grating monochromator is found to realize very good energy resolut ion. This is demonstrated by the experimental photoabsorption spectra of th e Ar 2p(similar to 250 eV) and N-2 1s (similar to 400 eV) edges, which show the quality competitive to or better than the best results reported to dat e. In addition, the excellent performance is augmented by the high photon f lux of about 10(11) photons/s100 mA(-1)0.02%(-1) b.w., low degree of higher order light (less than 1%) and high circular polarization at the experimen tal stations.
