Creating extended, highly homogeneous plasma columns like that required by plasma wakefield accelerators can be a challenge. [...]

Controlled Growth of the Self-Modulation of a Relativistic Proton Bunch in Plasma / AWAKE Collaboration
A long, narrow, relativistic charged particle bunch propagating in plasma is subject to the self-modulation (SM) instability. We show that SM of a proton bunch can be seeded by the wakefields driven by a preceding electron bunch. [...]

Analysis of Proton Bunch Parameters in the AWAKE Experiment / AWAKE Collaboration
A precise characterization of the incoming proton bunch parameters is required to accurately simulate the self-modulation process in the Advanced Wakefield Experiment (AWAKE). This paper presents an analysis of the parameters of the incoming proton bunches used in the later stages of the AWAKE Run 1 data-taking period. [...]

Long-range propagation of ultrafast ionizing laser pulses in a resonant nonlinear medium / Demeter, G. (Wigner RCP, Budapest) ; Moody, J.T. (Munich, Max Planck Inst.) ; Aladi, M. (Wigner RCP, Budapest) ; Bachmann, A.-M. (Munich, Max Planck Inst.) ; Batsch, F. (Munich, Max Planck Inst.) ; Braunmüller, F. (Munich, Max Planck Inst.) ; Djotyan, G.P. (Wigner RCP, Budapest) ; Fedosseev, V. (CERN) ; Friebel, F. (CERN) ; Gessner, S. et al.
We study the propagation of 0.05-1 TW power, ultrafast laser pulses in a 10 meter long rubidium vapor cell. The central wavelength of the laser is resonant with the $D_2$ line of rubidium and the peak intensity in the $10^{12}-10^{14} ~W/cm^2$ range, enough to create a plasma channel with single electron ionization. [...]

Simulation and Experimental Study of Proton Bunch Self-Modulation in Plasma with Linear Density Gradients / AWAKE Collaboration
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 results agree with the experimental results reported in arXiv:2007.14894v2: with negative gradients, the charge of the modulated bunch is lower than with positive gradients. [...]

Transition between Instability and Seeded Self-Modulation of a Relativistic Particle Bunch in Plasma / AWAKE Collaboration
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 that, with sufficient initial amplitude ($\ge(4.1\pm0.4)$ MV/m), the phase of the modulation along the bunch is reproducible from event to event, with 3 to 7% (of 2$\pi$) rms variations all along the bunch.

Experimental study of extended timescale dynamics of a plasma wakefield driven by a self-modulated proton bunch / AWAKE Collaboration
Plasma wakefield dynamics over timescales up to 800 ps, approximately 100 plasma periods, are studied experimentally at the Advanced Wakefield Experiment (AWAKE). The development of the longitudinal wakefield amplitude driven by a self-modulated proton bunch is measured using the external injection of witness electrons that sample the fields. [...]

Experimental Study of Wakefields Driven by a Self-Modulating Proton Bunch in Plasma / AWAKE Collaboration
We study experimentally the longitudinal and transverse wakefields driven by a highly relativistic proton bunch during self-modulation in plasma. We show that the wakefields' growth and amplitude increases with increasing seed amplitude as well as with the proton bunch charge in the plasma. [...]
