Figure 7
Phase difference induced by quadrupoles in the horizontal phase-space at the middle of the upstream undulator in the double mini-βy lattice, (a) in the soft X-ray energy at 220 eV from an EPU48, (b) in the hard X-ray energy of 20 keV from an IU22. The horizontal and vertical scales of the figures are ±σx and ±σx′ of the horizontal electron beam size and angular divergence, respectively. The vertical emittance and energy spread of the electron beam is zero.
