ID09 - White Beam Station - Time-resolved Beamline

Synopsis

Beamline for experiments with a time resolution down to 100 picoseconds. Structural changes are initiated by short laser pulses and are probed by delayed X-ray pulses. The setup includes unique X-ray optics for intense polychromatic beams.

Technical details

ID09 permits time-resolved X-ray diffraction and solution scattering experiments. One unique feature is the intense pink beam from the in-vacuum undulator U17 [1]. The U17 is a "single-harmonic" undulator tunable between 15 and 19.5 keV. The chopper system can select 100 picosecond, microsecond or millisecond pulses [2].
