Beam intensity profiles, normalized to maximum intensity, at several harmonic energies were obtained while keeping the gap of the IVU at 5.1 mm (x, y: horizontal and vertical directions of the slit, respectively). Profiles in (a) and (b) were acquired at the minimum energy of the third harmonics in planar and tapered modes, respectively; those in (c) and (d) were acquired at 5.6 keV in planar and tapered modes, respectively. |
