Figure 8
Small spot (a, c) versus large spot (b, d) setting of the refocusing mirror. (a, b) Distribution of X-ray flux on a scintillator plate at normal incidence at the designated sample position. (c, d) ARPES measurements of the Shockley state of the Cu(111) surface at = 70 eV. The measurements were taken in fixed-energy mode at a pass energy of 10 eV and integrated over 10 min. The line graphs show the integrals over one dimension (a, b), or the profiles along the dash-dotted lines (c, d), respectively. Full width at half-maximum is indicated. |
