The 6 m low-energy spherical grating monochromator (6 m-LSGM) beamline at SRRC is at its commission stage. The 6 m-LSGM beamline, which covers photon energies from 15 to 200 eV, is based on Dragon concept with spherical gratings and movable exit slit. Some of the commission data will be presented in this paper. The photoabsorption spectra of Ar, He, and Kr have been recorded with resolution so far unattained in the vacuum ultraviolet region.
