Improving the efficiency of laser-plasma accelerators

Laser-Plasma Accelerators can produce electric fields exceeding 100 GV/m, that are about three orders of magnitude larger than those obtained by radiofrequency-cavity accelerators. They could thus allow for a drastic decrease of the size of accelerators for scientific, medical and industrial applications. Yet, several bottlenecks have to be solved before these applications can be really implemented. It is notably necessary to demonstrate the efficient production of high-quality, multi-GeV electron beams at a high-repetition rate. The project tackles this problem by exploring new methods for increasing the charge and the energy of the electron beams, with techniques that are compatibles with arbitrarily high laser powers and repetition rates.
