Figure 4
(a) Single-pulse FEL snapshot diffraction pattern of PS II, showing Bragg peaks and continuous diffraction from the disordered crystal and diffuse scattering from the solvent medium. (b) Single-pulse FEL pattern from the jet that was free of crystals, showing only the scattering from the liquid. The colour scale spans 0 to M = 3000 adu for part (a) and 0 to M = 2000 adu for part (b). The incident beam was linearly polarized, in the horizontal direction in this view. The patterns have not been corrected by the polarization factor. |
