Simulation studies for a EEHG seeded FEL in the XUV — •Vanessa Grattoni1, Christoph Lechner1, Wolfgang Hillert2, Georgia Paraskaki1, and Ralph Assmann1 — 1DESY, Hamburg, Deutschland — 2Universität Hamburg, Hamburg, Deutschland
Echo enabled harmonic generation (EEHG) is a promising technique for seeded free electron lasers not only to go down to wavelengths of 1 nm, but also to simplify the schemes that are currently used to achieve a similar wavelength range (double-cascaded HGHG). Thus a study optimizing the EEHG performance in the wavelength range from 60 to 4 nm is performed, assuming a linear accelerator operated at electron beam energies of 750 MeV and 1.35 GeV. These two working points are analyzed in detail for two different seed laser frequencies: visible and UV.
