Demonstration of a 10-metre-long discharge plasma source for plasma wakefield acceleration
C. Amoedo, N. Lopes, N. E. Torrado +13
The AWAKE experiment at CERN uses high-energy proton bunches to drive plasma wakefields capable of accelerating electron bunches up to hundreds of GeV in a single plasma. Realising…

Experimental Observation of Motion of Ions in a Resonantly Driven Plasma Wakefield Accelerator
M. Turner, E. Walter, C. Amoedo +15
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 wakefi…

Filamentation of a Relativistic Proton Bunch in Plasma
L. Verra, C. Amoedo, N. Torrado +12
We show in experiments that a long, underdense, relativistic proton bunch propagating in plasma undergoes the oblique instability, that we observe as filamentation. We determine a…
