Schematic of the experimental set-up for lens evaluation. The lens was placed on a four-axis motorized stage. Slits A and B, with downstream ionization chambers, were motorized for motion perpendicular to the X-ray beam. The position of slit B along the X-ray beam was manually adjusted on an optical rail. A CCD camera was also sometimes mounted at the position of slit B.  [article HTML]
