The determination of flux

the calibration of photon energy and the angle-resolved photoemission experiment were reported in this paper. During the process of commissioning of the station the photon flux was measured by photo-electronic diode (IRD AXUV-100) and the response curves for three different gratings were obtained. Photon energies of the whole range were calibrated using the second harmonic for high energies and the fermi edge of gold for low energies. And the resolution of the system was also calculated. At last the alignment of the electron detector was performed by the synchrotron radiation and laser beam and the ARPES for copper crystal was obtained to test the whole system. The results show that the surface station in the NSRL can satisfy the users for their ARPES experiments.
