The characteristics of the beamline used for PES (photoelectron spectroscopy) and SEXAFS (surface extend x-ray absorption fine structure) studies at the Photon Factory are described. Monochromatic photons are available in the energy range between 50--900 and 2500--4000 eV. This has been accomplished using a grating/crystal monochromator with a combination of two paraboloidal mirrors. The synchrotron radiation is focused by a set of paraboloidal mirrors at a 1.0/degree/ incident grazing angle. The plane grating/mirror combination has covered vacuum ultraviolet region of 50--900 eV with 1200 and 2400 g/mm gratings. The InSb (111) double crystals have covered soft x-ray region of 2500--4000 eV. The performance of the gratings in respect to intensity, resolution, and the effect of ''on blaze operation'' is discussed. The Bragg peak searching system in crystal mode and its performance are also described. With the use of InSb(111) crystals, the energy range below 2700 eV will be covered with precise roll adjustment of both 1st and 2nd crystals.
