Advanced quasistatic approximation
P. V. Tuev, R. I. Spitsyn, K. V. Lotov
The quasistatic approximation (QSA) is an efficient method of simulating laser- and beam-driven plasma wakefield acceleration, but it becomes imprecise if some plasma particles mak…
Transition between Instability and Seeded Self-Modulation of a Relativistic Particle Bunch in Plasma
F. Batsch, P. Muggli, R. Agnello +94
We use a relativistic ionization front to provide various initial transverse wakefield amplitudes for the self-modulation of a long proton bunch in plasma. We show experimentally t…
Wakefield decay in a radially bounded plasma due to formation of electron halo
R. I. Spitsyn, K. V. Lotov
There is a new effect that can limit the lifetime of a weakly nonlinear wakefield in a radially bounded plasma. If the drive beam is narrow, some of the plasma electrons fall out o…
Experimental study of extended timescale dynamics of a plasma wakefield driven by a self-modulated proton bunch
J. Chappell, E. Adli, R. Agnello +96
Plasma wakefield dynamics over timescales up to 800 ps, approximately 100 plasma periods, are studied experimentally at the Advanced Wakefield Experiment (AWAKE). The development o…
Proton beam defocusing in AWAKE: comparison of simulations and measurements
A. A. Gorn, M. Turner, E. Adli +96
In 2017, AWAKE demonstrated the seeded self-modulation (SSM) of a 400 GeV proton beam from the Super Proton Synchrotron (SPS) at CERN. The angular distribution of the protons defle…
Proton Bunch Self-Modulation in Plasma with Density Gradient
F. Braunmüller, T. Nechaeva, AWAKE Collboration
We study experimentally the effect of linear plasma density gradients on the self-modulation of a 400\,GeV proton bunch. Results show that a positive/negative gradient in/decreases…
