Experimental demonstration of proton bunch self-modulation and of electron acceleration in a 10m-long plasma — •Patric Muggli for the AWAKE collaboration — Max Planck Institute for Physics, Munich, Germany

Self-modulation of a long, relativistic particle bunch in a dense plasma is a proposed scheme to drive large amplitude wakefields over a long distance. Externally injected electrons can then gain large amounts of energy in a single plasma, thereby avoiding well-known staging issues. We will explain the principle of the AWAKE experiment that uses a 400GeV proton bunch to demonstrate this acceleration scheme. We will show detailed experimental results demonstrating the control of the self-modulation process through two seeding methods. We will also show that externally injected MeV electrons were accelerated to the GeV energy scale. Finally, we will briefly outline future experiments and possible applications of this acceleration scheme.
