摘要
The optical layout and the expected performance of the new high-flux SAXS beamline at ELETTRA is presented. From the high-power wiggler spectrum the three discrete energies 5.4, 8, and 16 keV will be selected with a double-crystal monochromator which contains three pairs of separated asymmetrically cut plane Si(111) crystals. Downstream, the beam will be focused by a torodial mirror. The optical axis of the beamline will be horizontally 1.25 mrad off wiggler axis and the beamline will accept about 1 mrad horizontally and 0.3 mrad vertically. The beamline will operate with a SAXS resolution between 10 and at least 1000 Å in d spacing at 8 keV and has been optimized with respect to extreme flux. A flux at the sample in the order of 1013 ph/s is expected for 8 keV photons (2 GeV, 400 mA). It will be possible to perform wide angle scattering measurements in the range of 3.5 and 7 Å d spacing at 8 keV simultaneously. © 1995 American Institute of Physics.
