“…The proton driven plasma wakefield acceleration is experimentally studied at the AWAKE facility at CERN [10][11][12]. The first experiments showed the possibility of exciting the wakefield using the proton beam of the super proton synchrotron (SPS) [13,14] and accelerating electrons up to 2 GeV in a plasma cell 10 m long [15,16]. The SPS proton bunches are hundreds of times longer than the plasma wavelength and efficiently drive the wave only after they are micro-bunched as a result of seeded self-modulation (SSM) [17][18][19][20][21][22][23].…”

Seeded self-modulation in a plasma can transform a long proton beam into a train of micro-bunches that can excite a strong wakefield over long distances, but this needs the plasma to have a certain density profile with a short-scale ramp up. For the parameters of the AWAKE experiment at CERN we numerically study which density profiles are optimal if the self-modulation is seeded by a short electron bunch. With the optimal profiles, it is possible to ‘freeze’ the wakefield at approximately half the wavebreaking level. High-energy electron bunches (160 MeV) are less efficient seeds than low-energy ones (18 MeV), because the wakefield of the former lasts longer than necessary for efficient seeding.
