Figure 2
The cell based on a thin-walled glass/quartz capillary, (B). Top: the sample is loaded under Ar into a capillary closed at one end, the funnel is sealed with vacuum grease, and the capillary is glued into a socket weld gland with the funnel on the side of the VCR fitting. A 1/8 inch metal gasket is placed next to a 1 cent coin. Middle: the Tee union is fixed in the goniometer head and connected on one side via a PEEK capillary to a gas system; the spare outlet is closed by a cap. Bottom: the cell in operation, the nozzle of the Oxford Cryostream pointing from the top to the same position on the sample as the X-ray beam; the beamstop is shown on the right. During temperature-programmed scans, the cell is typically rotated by Δφ = ±30° during each X-ray exposure within the same angular range. |
