Description
The beam-driven plasma photocathode wakefield acceleration concept [1] allows decoupled laser injection of electron bunches with emittance and brightness reach many orders of magnitude better than state-of-the-art [2]. After successful proof-of-concept demonstration at SLAC FACET in the “E-210: Trojan Horse” project [3], we now embark on the next experimental phase around the “E-310: Trojan-II” flagship and five related experiments at FACET-II, where better incoming beams and improved setup may unleash the full potential of the scheme. Plans for FACET-II experiments and complementary progress and plans on hybrid LWFA->PWFA with automatically synchronized plasma photocathodes will be presented. Looking further ahead, the UK STFC has initiated the UK-US “PWFA-FEL” programme, which aims to push exploitation of the ultralow emittance and ultrahigh brightness of beams which may be obtainable from upcoming installations of plasma photocathodes. This project will explore the benefits of ultrahigh brightness beams and will also be used to assist experimental programmes on PWFA and plasma photocathodes at Daresbury’s CLARA facility and at FACET-II, and at future hybrid LWFA->PWFA systems.
