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. [...]

Betatron radiation diagnostics for AWAKE Run 2 / Williamson, B (Manchester U. ; Cockcroft Inst. Accel. Sci. Tech.) ; Xia, G (Manchester U. ; Cockcroft Inst. Accel. Sci.

AWAKE Run 2 aims to preserve the transverse normalised emittance of an externally injected electron beam throughout acceleration, requiring a new diagnostic to measure the beam emittance after the accelerating plasma stage. Spectroscopy of the betatron emission from the electron beam could be suitable for this case. [...]

Evolution of a plasma column measured through modulation of a high-energy proton beam / AWAKE Collaboration
Plasma wakefield acceleration is a method for accelerating particle beams using electromagnetic fields that are orders of magnitude larger than those found in conventional radio frequency cavities. [...]

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. [...]

The advanced wakefield experiment (AWAKE) at CERN is the first proton beam-driven plasma wakefield acceleration experiment. The main goal of AWAKE RUN 1 was to demonstrate seeded self-modulation (SSM) of the proton beam and electron witness beam acceleration in the plasma wakefield. [...]

The AWAKE collaboration prepares a proton driven plasma wakefield acceleration experiment using the SPS beam at CERN. A long proton bunch extracted from the SPS interacts with a high power laser and a 10 m long rubidium vapor plasma cell to create strong wakefields allowing sustained electron acceleration. [...]

Proton Driven Plasma Wakefield Acceleration in AWAKE / AWAKE Collaboration
In this article, we briefly summarize the experiments performed during the first Run of the Advanced Wakefield Experiment, AWAKE, at CERN (European Organization for Nuclear Research). The final goal of AWAKE Run 1 (2013 - 2018) was to demonstrate that 10-20 MeV electrons can be accelerated to GeV-energies in a plasma wakefield driven by a highly-relativistic self-modulated proton bunch. [...]

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. [...]

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. [...]
