Accessible SAXS and WAXS range

Small angle:

Real space: 1-140 nm (8 keV)
                     1-63 nm (16 keV)



Wide angle:

angular region from 17 - 85^o  (2Theta)



SWAXS:

Simultaneous SAXS- and WAXS-measurements can be performed using a Pilatus3 1M detector for the SAXS signal, and a Pilatus 100k detector for the WAXS-range.

For transmission experiments, also a specially designed vacuum chamber (SWAXS-nose, see Annual Report of 1996/97, p. 32) can be used which allows to use both scattering areas below (for SAXS) and above (for WAXS) the direct beam, respectively. The overall length of the SWAXS-nose in horizontal direction, measured from the sample position, is 512 mm and the fixed sample to WAXS-detector distance is 324 mm. Therefore, at the shortest SAXS camera-length an overlap in the d-spacings covered by the SAXS- and WAXS-detectors, respectively, is possible: then, the common regime lies around 9 Å (at 8 keV, using for WAXS the 2Theta = 9.4 - 27.6^o range).
