Opportunities for THz-pump x-ray-probe experiments at free-electron lasers — •Wilfried Wurth — Physik Department und CFEL, Universität Hamburg — DESY Photon Science, Hamburg

New light sources based on linear accelerators such as the free-electron laser FLASH at DESY in Hamburg in the extreme ultraviolet and soft x-ray regime provide ultrashort, extremely powerful short wavelength pulses with unprecedented coherence properties.

With these new sources it is possible to extend the well-established x-ray spectroscopy or scattering techniques for the investigation of the static electronic and geometric structure of matter to the time domain. The short electron bunches necessary to produce the short wavelength pulses can at the same time be used to generate coherent THz radiation which is fully synchronized to the XUV- or x-ray pulses.

In the talk the possibilities for THz-pump x-ray-probe at the FLASH facility will be reviewed and examples for THz-pump x-ray probe experiments performed at FLASH will be given.
