Experimental Observation of the Motion of Ions in a Resonantly Driven Plasma Wakefield Accelerator

Patrick Blanchard, Ambrogio Fasoli, Ivo Furno, Yanis Andrebe, Riccardo Agnello, Christine Stollberg

We show experimentally that an effect of motion of ions, observed in a plasma-based accelerator, depends inversely on the plasma ion mass. The effect appears within a single wakefield event and manifests itself as a bunch tail, occurring only when sufficie ...
