FIG. 15.
Illustration of the effective X-ray beam intersecting the free jet in four characteristic cases. (a) Scrambled flow where . (b) Scrambled flow where . (c) Focused flow where . (d) Focused flow where . The real X-ray beam is shown in solid red, while the effective beam is a transparent red cylinder. Crystals are in yellow, and the jet is blue. A darker blue cylinder represents the jet-within-jet in the flow focused regime.
