Microfocus Option
What?
Requirements
Brilliance: 1017-1018 photons/s/(mrad)2/(mm)2
Energy range: Continuous from 0.2 nm (6 keV) to 0.07 nm (20 keV) optimized for 0.1 nm (12.4 keV).Photon flux: 1012 Ph/sBand Pass: 10-4
With standard focusing Beam size at sample/detector: 10m (V), 150 m (H) Divergence at sample/detector: 0.02mrad(V), 0.04 mrad (H)
With microfocus Beam size at sample/detector < 5m diameter. Divergence at sample/detector: 0.05 mrad Positional stability: 1 % RMS during 1-10 seconds
What?
Microfocus optics
Mirror ID
Vacuum undulator will be required due to the higher flux and to the lower divergence
Monochromator
A double crystal Si (111) monochromator or Multilayer
Toroidal focusing mirror (vertical and horizontal focusing).
Pin-hole collimation (5 and 10 m collimators).Kirkpatrick-Baez mirror. ≤ 1 m Fresnel lenses (0.1-0.5 m with a 109 ph/s flux).Beryllium Compound Refractive Lenses.
