Performance of the Dragon soft x-ray beamline (invited)

Abstract

We report on the performance of a newly constructed synchrotron radiation soft x-ray beamline. This beamline, dubbed Dragon, is a spherical version of the cylindrical element monochromator design proposed previously. By measuring the K-edge absorption spectra of condensed nitrogen, it is determined that this monochromator has achieved resolving power 104 at 400-eV photon energy, using its full 15 by 1 mrad angular acceptance. The ideas and advantages contained in the CEM design have also been experimentally confirmed.
