Helium FIM images of the dislocation (shown by arrow heads) at the special non-CSL boundary with misorientation angle 19° recorded during an atom-by-atom field evaporation showing the violation of continuity of the {110} circular atomic steps across the boundary before (ac) and after (d), (e) a local GB slip event, and corresponding stereographic projection (f). Imaging conditions: field strength of 44 V/nm, T = 77 K
