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 y i 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.
