Comparison of Ti 1s HAXPES spectra measured under different conditions. Widths indicated in the figure were determined by means of the least-squares fitting procedure employing the Gaussian function. (Top) Ordinary sweep mode, BL19LXU of SPring-8 with Ep = 200 eV, slit = 0.5 mm and photon bandwidth ≃ 60 meV. (Middle) Ordinary sweep mode, BL3 of SACLA with Ep = 200 eV, slit = 4 mm and photon bandwidth ≃ 1 eV. (Bottom) Shot-to-shot image mode, BL3 of SACLA.
