The source

 

• Micro-source Genix Collimated Cu (Xenocs)

• Wavelegnth 1.54 Å / 8 keV (Cu Kα)

• Kα contamination ≤ 0.5%

• Beam size at the output of the mirror : 1.1 x 1.5 mm² (FWHM)

• Flux : 170 x10e6 ph/s

• Divergence ≤ 0.7 mrad (FWHM)

• Beam collimation :  FOX2D inf2® mirror => parallel beam

• 2 sets of four scaterless slits® => avoid parasit scattering from slits.
