Figure 5
Post-mortem diffraction patterns of MP′2 and nano-diffraction maps (a pixel on the map is the intensity integrated on a selected region of the detector), after 610 MPa (state u′2). (a)–(c) A diffraction pattern collected at the centre of the pillar with an acquisition time of 0.02 s. (a) On this pattern we select areas on the detector: (b) an ROI and (c) the complementary part. (d)–(f) Corresponding integrated intensity maps, showing that the ROI is associated with the pedestal only. The coordinate yi describes the horizontal direction perpendicular to the beam propagation direction. The colorbar above (a) applies to (a), (b) and (c), with white meaning masked area. |
