Figure 11
The measured maximum flux gain from an 8 mrad capillary, Peb605, at the CHESS D station is about 455 in both the vertical and horizontal pinhole scans, close to the calculated gain of 460 with pinhole convolution, and 503 without pinhole convolution, with capillary slope errors of 130 µrad. With intensity plotted on a logarithmic scale, the focusing quality is more easily evaluated around the spot tails. The pedestal is the direct beam through the 470 µm tip opening.
