Abstract

We summarize and explain the realization of witness particle injection into wakefields for the AWAKE experiment. In AWAKE, the plasma wakefields are driven by a self-modulating relativistic proton bunch. To demonstrate that these wakefields can accelerate charged particles, we inject a \unit[10-20]MeV electron bunch produced by a photo-injector. We summarize the experimental challenges of this injection process and present our plans for the near future.
