Description
The European XFEL combines a superconducting linear accelerator and long variable-gap undulators to deliver hard X-ray pulses at megahertz repetition rates in 10 Hz burst mode. Building on this capability, we have recently developed the so-called self-chirping operation mode at the SASE2 beamline to generate isolated high-power attosecond hard X-ray pulses. This contribution presents an overview of the underlying concepts, beam dynamics optimization and constraints of attosecond hard X-ray generation. We summarize the R&D efforts and first user delivery experience of the self-chirping mode. In addition, we will discuss our plans for future development.
