Abstract
This contribution presents the concept of installing a table-top high harmonic generation (HHG) source with high repetition rates at the Soft X-ray Port (SXP) instrument of the European XFEL. The compact implementation will enable studies in the extreme ultraviolet (XUV) range between 20 eV and 72 eV at the SXP interaction point using the existing experimental setup: a time-of-flight momentum microscope. This will allow for time-resolved investigations, which are complementary to those conducted with the soft X-ray SASE 3 undulator covering a spectral range from about 0.3 keV to 3 keV. This project will enable unique optical pump - XUV probe experiments, facilitate the preparation of soft X-ray beamtimes, contribute to the development of a robust research program at SXP, and provide opportunities for other groups at the European XFEL as well as the international user community alike.
