[en] An excellent software applied to synchrotron radiation experiment is introduced. With this software, due to operation of photoelectron spectroscopy control over beamlines changes from Rowland circle to a single DRAGON type, and photon transmission is improved 2-3 times. Not only X-ray Photoemission Spectroscopy (XPS) excited by X-ray gun source but also Energy Distribution Spectroscopy (EDC). Constant Final Spectroscopy (CFS) and constant initial spectroscopy (CIS) excited by synchrotron radiation can be done by the software. It runs with a graphic main menu in which operation is visible and stable, and thus suitable scientific experiments
