Abstract:
In 2017, the European XFEL successfully achieved first lasing. Currently, up to 3 SASE FEL lines, SASE1, SASE2, and SASE3 can be operated quasi-simultaneously. Mid-term upgrades for the European XFEL are now under discussion, which will consist in the implementation of two novel XFEL lines, SASE4 and SASE5. One feasible idea for a soft X-ray FEL line consists of an external-seeded FEL, which would largely increase the longitudinal coherence properties of the radiation, compared to SASE, and will be just as powerful. In this presentation, we will report about the current status of our studies on external laser seeding feasibility using the high-electron beam energy of the European XFEL, with cascaded High-Gain Harmonic Generation (HGHG) and Echo-Enabled Harmonic Generation (EEHG).
