Description
Recent advancements in plasma-based accelerators have ignited "the race for wakefield-driven FELs" [1]. However, FELs at soft and hard X-ray wavelengths require electron beams with dramatically improved 6D brightness. The author presents comprehensive strategies towards generating ultra-high 6D brightness electron beams in beam-driven plasma wakefield acceleration (PWFA). These ultra-high 6D brightness electron beams may enable novel photon and fundamental science modalities [2]. One direct ramification of this new class of electron beams is a blueprint for an ultra-compact attosecond-Angstrom class FEL [3]. Further, the author will explain how these high-brightness PWFA stages can enhance the capabilities and modalities of existing and future linac-based FELs.
