Abstract

The European XFEL R&D project, STERN, aims to provide X-ray users with an accelerator-based THz source for pump probe science. STERN will produce THz radiation using diffraction radiation and wakefield based approaches. In this paper we provide an overview on our theoretical and simulation methods to select a variety of wakefield radiators over our frequency range of interest (300 GHz - 30 THz). Such wakefield structures offer a novel option for delivering versatile THz sources tailored to next-generation pump-probe experiments.
