The multi-exposure X-ray topographs of the 666 reflection taken with Mo Kα1 of samples (a) S95 and (b) S2.2. The scanning angular step was Δθ = 4.5 arcsec. The topographs were recorded on Ilford L4 nuclear plates, with 30 min for each exposure and 2.5 h exposure time in total, by the generator operated at 55 kV, 240 mA. |
