Overview
ID09 is an insertion device beamline designed for time-resolved experiments on solid state materials, liquids and biological samples.
The unique feature of ID09 is the focused pink beam which can be used for time-resolved diffraction or solution scattering. The exposure time is typically in the microsecond range for experiments on proteins in solution but can reach 100 ps in timing mode operation (7/8+1, hybrid, 4-bunch). The relative timing of the laser and X-ray pulses is controlled electronically from ps to second time scale (laser vs. X-ray jitter < 5 ps).
An high speed chopper is used as fast mechanical shutter to select the flash produced by a single bunch out of the high frequency train of flashes produced by the storage ring. The resulting repetition rate of the train of single bunch X-ray pulses is 1 kHz. A fast shutter able to reduce the X-ray pulses repetition rate is used for experiments on slow reactions or which require exposing the sample to a single X-ray pulse.
Reaction triggering instrumentation available at ID09 include: (i) a Ti:sapphire picosecond laser tunable in the UV-Vis-NIR; (ii) a Nd:YAG nanosecond laser tunable in the 410-2000 nm range (+ 3rd harmonic at 355 nm); (iii) a high power Nd:YAG nanosecond laser with nearly top hat profile (1st and 2nd harmonic); (iv) a rapid mixing stopped-flow system with a few milliseconds dead time.
