Plasma-based acceleration experiments at the SPARC_LAB test facility

The current goal of the world wide R&D programs is to demonstrate the stable and repeatable acceleration of high brightness electron beams (HBEBs) in plasma structures. The scheme proposed at the SPARC_LAB test facility is based on the external injection of electrons in the plasma. Two different mechanisms are proposed: an external injection laser wakefield acceleration (LWFA), by combining the multi-hundreds TW power laser (Flame) and the HBEB from the photo-injector, and a particle-driven resonant plasma wakefield acceleration (rPWFA), by using
a train of high brightness electron bunches.
