“…Such schemes have recently become popular again, as they offer the advantage of symmetric acceleration of electrons and positrons [34][35][36][37] and allow the use of positively charged drivers. 3,4,38 The importance of the discovered effect will increase as plasma acceleration techniques will approach collider applications and the requirements to the witness quality will become more stringent.…”

Witness emittance growth caused by driver density fluctuations in plasma wakefield accelerators

We discovered a novel effect that can cause witness emittance growth in plasma wakefield accelerators. The effect appears in linear or moderately nonlinear plasma waves. The witness experiences a time-varying focusing force and loses quality during the time required for the drive beam to reach transverse equilibrium with the plasma wave. The higher the witness charge, the lower the emittance growth rate because of additional focusing of the witness by its own wakefield. However, the witness head always degrades, and the boundary between degraded and intact parts gradually propagates backward along the witness bunch.

“…These waves can be stabilized by binding them to the leading intense beam of charged particles. Waves behind such beams are termed wakefield and acceleration in such wake waves has been considered in other research (see [6,7]). Plasma waves can be excited using charged-particle beams (beam-driven plasma wakefield acceleration [PWFA]), as well as by laser radiation (laser wakefield acceleration) [8].…”

A model of one-dimensional (1D) cold plasma with an external train of rigidly structured bunches with diverse charges has been introduced. In this model, a solution is presented that cancels the wakefield after the train is found. The density of such bunches can be much greater than the density of the plasma, and a high amplitude electrical field arising inside the train can be used for charged-particle acceleration. In addition, analytical and numerical simulations have been performed.

“…Proton-beam-driven plasma wakefield acceleration promises to increase the lepton energy which is available to scientific laboratories [1][2][3]. The first step towards future colliders based on this principle is the AWAKE experiment at CERN [4][5][6], which has already demonstrated controlled self-modulation of the proton beam [7,8] (the key element of the concept) as well as electron acceleration in the proton-driven wakefield [9].…”

The "Advanced Proton Driven Plasma Wakefield Acceleration Experiment" (AWAKE) aims to accelerate leptons via proton-beam-driven wakefield acceleration. It comprises extensive numerical studies as well as experiments at the CERN laboratory. The baseline scenario incorporates a plasma volume of approximately 62 cm 3 . The plasma wavelength is about 1.25 mm and needs to be adequately resolved, using a minimum of 130 points per plasma wavelength, in order to accurately reproduce the physics. The baseline scenario incorporates the proton beam micro-bunching, the concurrent non-linear wakefield growth as well as the off-axis electron beam injection, trapping and acceleration. We present results for the first three-dimensional simulation of this baseline scenario with a full model, using a sufficient resolution. The simulation consumed about 22 Mch of computer resources and scaled up to 32768 cores, thanks to a multitude of adaptions, improvements and optimization of the simulation code PSC. Through this large-scale simulation effort we were able to verify the results of reduced-model simulations as well as identify important novel effects during the electron injection process.
