Figure 7
The measured intensity profile from the BSG625 capillary (crosses, taken with 10 µm pinhole scan) at the CHESS D station is close to the calculated profile with slope errors of 0.145 mrad (dots, without convolution and solid line after 10 µm pinhole convolution). Compared with the BSG2 capillary, this shorter relative length capillary has a higher percentage of focused X-rays at the spot center area. The pedestal in the measured profile is the direct beam from the 230 µm capillary tip opening, which can be stopped with a beam block upstream of the capillary.
