Description
Electron beams from laser-plasma-accelerators often have rather large energy spreads and only limited
reproducilibility, which can be a showstopper for many key applications. Nevertheless, they have parameters which indicate
that they are highly suited as electron bunch drivers in plasma wakefield acceleration afterburner stages. For example, large energy spreads do not at all decrease their ability to drive strong plasma waves. Hybrid concepts involving multiple electron bunches [1] and highest-quality bunches generated inside the second plasma stage [2] (also known as Trojan Horse plasma wakefield acceleration), as well as hybrid scenarios where electron bunches from conventional accelerator stages are used as drivers have been developed. Here we discuss the potential of such hybrid systems for a dramatic improvement of electron beam stability and quality, which may allow to build free-electron-lasers which are ultracompact yet have better unprecedented performance, and the experimental advances in the field.
