Description
Ultrahigh Brightness Facility Upgrades based on Plasma Photocathodes
Plasma accelerators can provide accelerating electric fields of tens of GV/m, which makes them interesting building blocks for future compact accelerators e.g. for high energy physics and light sources. In addition to the use of plasma for high-gradient acceleration, the hybrid "Trojan Horse" concept offers to use plasma also as an ultrahigh quality electron source via realisation of plasma photocathodes. Normalised emittance levels otherwise attainable only by using large damping rings, and electron (5D) brightness levels exceeding those at e.g. LCLS by many orders of magnitude may be possible. The plasma photocathode therefore is a major impetus for development of plasma wakefield acceleration and plasma-driven light sources. The development of this idea and technology will be summarised, including fresh results from the multi-year, multi-institutional "E210: Trojan Horse" campaign at SLAC FACET, the world's pioneering PWFA facility. Prospects and challenges of implementation of plasma photocathodes at upcoming linac-based facilities such as FACET-II, FLASHForward, BNL ATF-II, CLARA, INFN etc. and for international projects such as EuPRAXIA, but also as ultrahigh beam brightness transformers for laser-plasma-accelerators will be discussed.
