Wakefield dechirping with a dielectrically lined waveguide at ELBE — •Franziska Reimann1, Ursula van Rienen1, Peter Michel2, and Ulf Lehnert21Universität Rostock, Institut für Allgemeine Elektrotechnik; Rostock, Germany — 2Helmholtz-Zentrum Dresden-Rossendorf; Dresden-Rossendorf, Germany

Dielectrically lined waveguides are planned to be used as a passive wakefield dechirper[1] for the electron beam at the ELBE facility of the Helmholtz-Zentrum Dresden Rossendorf.

In this work we introduce the design of such a passive wakefield dechirper based on the analysis of dielectrically lined rectangular waveguides with a semi-analytical model developed at the University of Rostock. The generality of this model allows for a quick calculation of the wakefields of numerous different beam types via the Green's function method.

In this work, we present the dechirped phase-spaces of a variety of beam distributions, as well as the theoretically possible dechirping for the ELBE beam. Furthermore, we present an experimental structure planned at the ELBE facility to verify the calculated dechirping effect.
