17C1 W200 - EXAFS


Three wiggler X-ray beamlines have been specially designed to share the total 13 mrad of the horizontal radiation from the 25-pole 1.8-tesla wiggler insertion device located at beam port 17. These beamlines take 3, 4, 3 mrads of horizontal radiation, respectively. There is only 1.5 mrad separation left between each two adjacent beamlines for all the hardware mechanism assemblies.

The 17C wiggler beamline, which accepts the leftmost 3 mrad of the wiggler radiation, is designed to cover a wide photon spectrum ranging from 4.5 to 13 keV with a resolving power of up to 7000 for X-ray spectroscopy experiments. The whole beamline is an UHV design. Along the beamline, there is one graphite filter set at 11 m, one water-cooled collimating mirror at 12.3 m, one Si(111) double crystal monochromator (C-mono) at 16.9 m, one water-cooled bent toroidal refocusing mirror at 20.5 m, one high-order harmonic light rejection mirror at 27 m, and the sample position is at 30 m from the center of the wiggler device. A good focused white-light beam is available from this beamline.
