Proposed Ultrafast hard X-ray Beamline
Last modified: 2010-02-03
Ultrafast hard X-ray Beamline
The Ultrafast hard X-ray beamline is the first beamline at the Short-Pulse Facility SPF
which uses the short electron bunches which are available from the Linear Accelerator.
The beamline is designed to accommodate a wide range of ultrafast experiments and have
two separate end-stations. The front end station uses undulator radiation which and is
designed primarily for diffraction experiments. The back end station is optimized for
EXAFS experiments using wiggler radiation. The beamline is designed for pump-probe
experiments using visible pump radiation from a femtosecond laser which is synchronized
to the electron bunches from the LINAC. Hard X-ray probes will allow for time-resolved
structural determinations on the femtosecond time-scale.
