Wiggler


 

 



The wiggler, which is shared with the Macromolecular Crystallography beamline, consists of three 1.5 m long segments, each having 19 poles. The device can work with a minimum gap of 20 mm, which corresponds to K = 20 at 2 GeV. The main parameters of the wiggler are:
  • Critical Energy 4.1 keV
  • Photon Power 8.6 kW
  • Flux 3.5x1014 ph/s/mrad/0.1%BW (at 400 mA)
The wiggler radiation cone has a horizontal width of 9 mrad. From this the SAXS beamline accepts vertically 0.3 mrad, and horizontally +/-0.5 mrad at a 1.25 mrad off axis position. The resulting source size for 8 keV photons is 3.9 x 0.26 mm2 (horiz. x vert.).
