Top: time series recording crack propagation in a glass plate initiated by an accelerated bolt (all three ID19 insertion devices in use). Bottom: time series showing the growth of an individual crack (marked by the arrows: red shows the crack tip, yellow the propagated crack with the tip outside the field-of-view, one ID19 undulator in use). The grey-level contrast has been adapted for better visibility of the crack with respect to the images above. The pictures are acquired via single-bunch imaging at beamline ID19 (ESRF). |
