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. [...]

Proton beam defocusing in AWAKE: comparison of simulations and measurements / AWAKE Collaboration
In 2017, AWAKE demonstrated the seeded self-modulation (SSM) of a 400 GeV proton beam from the Super Proton Synchrotron (SPS) at CERN. [...]

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. [...]

Experimental observation of plasma wakefield growth driven by the seeded self-modulation of a proton bunch / AWAKE Collaboration
We measure the effects of transverse wakefields driven by a relativistic proton bunch in plasma with densities of $2.1\times10^{14}$ and $7.7\times10^{14}$ electrons/cm$^3$. We show that these wakefields periodically defocus the proton bunch itself, consistently with the development of the seeded self-modulation process. [...]

Experimental observation of proton bunch modulation in a plasma, at varying plasma densities / AWAKE Collaboration
We give direct experimental evidence for the observation of the full transverse self-modulation of a relativistic proton bunch propagating through a dense plasma. The bunch exits the plasma with a density modulation resulting from radial wakefield effects with a period reciprocal to the plasma frequency. [...]

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. [...]

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 Observation of Motion of Ions in a Resonantly Driven Plasma Wakefield Accelerator / AWAKE Collaboration
We show experimentally that an effect of motion of ions, observed in a plasma-based accelerator, depends inversely on the plasma ion mass. [...]

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. [...]

Acceleration of electrons in the plasma wakefield of a proton bunch / AWAKE Collaboration
High energy particle accelerators have been crucial in providing a deeper understanding of fundamental particles and the forces that govern their interactions. In order to increase the energy or reduce the size of the accelerator, new acceleration schemes need to be developed. [...]
