Description
Wakefield structures using metallic corrugated plates have demonstrated their capabilities in high-energy electron beam manipulation and diagnostics at low repetition-rate X-ray free-electron laser (XFEL) facilities. There has been a significant effort recently to utilize such devices at a MHz repetition rate. Here we first give an overview of the theoretical modeling and experimental achievements with corrugated structures in XFELs, then discuss the challenges in high repetition-rate XFELs and present our first experience of using such devices at the European XFEL. We show the generation of femtosecond hard X-ray FEL pulses with a few spectral spikes and operation up to a few hundred pulses at MHz repetition rate.
