The monochromator of the old soft x-ray beamline for photoemission spectroscopy covering spectral range from 60 -1000 eV was designed according to Rowland Circle Monochromator for energy resolution (E/{delta}E) over 2000 with slit widths of 40 {mu}m at NSRL. But the beamline suffers of low flux with high energy over 500 eV cut off and energy resolution bellow 1000 at practical flux. We reconstruct the beamline by replacement of the Kirkpatrick-Baez pre-focusing optics and the monochromator, energy resolution beyond 1000 and flux over 5x109 photons/s can be obtained with 50 {mu}m slit widths.
