Description
SwissFEL has two 1 m-long planar dielectric wakefield structures used for dechirping electrons in its hard X-ray beamline, Aramis. Simulations show the structures also support wakefields that can be used to accelerate following particle beams. Here we introduce the dielectric wakefield structures and ECHO2D simulations that show the longitudinal wake potential dependence on structure gap and drive beam length. We present simulations showing the thickness and permittivity of the structures’ dielectric coating determine the location of the accelerating wake potential. Finally, we compare the longitudinal wake potentials generated in the dielectric structures with those in SwissFEL’s planar metallic corrugated structures.
