Superconducting Wiggler Parameters:= 0.033 m Magnet Period Length
N = 35.5 Number of PeriodsB = 1.9 T Magnetic FieldK = 5.91 K Parameter
Front End Aperture: 1 mrad (H) x 0.24 mrad (V) Ray-tracing shows that the XAFS focus is ~1050 horizontal (FWHM) x ~257 vertical (FWHM) in size. The Kirkpatrick-Baez mirror pair reduces this down to ~[14-19]horizontal (FWHM) x [6-9] vertical (FWHM), using bent elliptical cylinders.
