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
