Figure 9
Picture of the crystal used in the helical measurements taken as the X-rays see the sample. The beam size was 7 µm in diameter; the crystal used was approximately 600 µm long by 150 µm wide and 100 µm deep. The normal data set was taken solely around the point on the left of the sample, whilst the helical data set was collected whilst the sample was translated between the two points on the right. |
