Abstract
A grazing incidence varied line spacing plane grating monochromator (VLS-PG M) has been designed and installed at the Photon Factory bending magnet bea mline, BL-1C. The monochromator is designed to cover 20 to 250eV with a hig h resolving power as well as a high photon flux and intended for a high-res olution angle-resolved photoemission study of quantum nano-structures. The resolving power of the beamline is observed to be more than 16,000 at aroun d 65 eV and exceeds 10,000 at all the covered energy ranges of the monochro mator with photon flux over 10(9) photons/s which shows that this monochrom ator reaches the expected design goals.
