CCD images of a crystal of ethynylbenzene (C6H5C≡CH, Fig. 7) at 0.40 GPa, recorded on a KUMA KM4 CCD diffractometer, Mo Kα radiation, with the DAC positioned in the ϕ = 0° mode and ω scans of 0.75°: (a) the DAC with the diamonds mounted on the steel edges of the backing plates (cf. Fig. 4); and (b) the same substance in the DAC with beryllium backing plates. The sample-crystal reflections are indicated with letters R, powder rings from the steel gasket with letter G; beryllium-powder rings with letters Be; and diamond reflections with letter D. |
