Wakefield-driven filamentation of warm beams in plasma
Erwin Walter, John P. Farmer, Martin S. Weidl +2
Charged and quasi-neutral beams propagating through an unmagnetised plasma are subject to numerous collisionless instabilities on the small scale of the plasma skin depth. The elec…
Simulation and Experimental Study of Proton Bunch Self-Modulation in Plasma with Linear Density Gradients
P. I. Morales Guzmán, P. Muggli, R. Agnello +88
We present numerical simulations and experimental results of the self-modulation of a long proton bunch in a plasma with linear density gradients along the beam path. Simulation re…
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…
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 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…
Stable particle acceleration in co-axial plasma channels
Alexander Pukhov, John P. Farmer
The attainable transformer ratio in plasma accelerators is limited by instabilities. Using three-dimensional particle-in-cell simulations, we demonstrate that these can be controll…
