Radiant power output of the beamline in different diffraction orders as a function of photon energy using the U180 undulator as radiation source. (a) First harmonic, 300 lines mm−1, SiC. (b) Third harmonic, 300 lines mm−1, Au. (c) Fifth harmonic, 1200 lines mm−1, Au. Resolving power E/ΔE = 100, storage-ring current 100 mA, electron energy 1.7 GeV. |
