AWAKE readiness for the study of the seeded self-modulation of a 400\,GeV proton bunch / AWAKE Collaboration
AWAKE is a proton-driven plasma wakefield acceleration experiment. % We show that the experimental setup briefly described here is ready for systematic study of the seeded self-modulation of the 400\,GeV proton bunch in the 10\,m-long rubidium plasma with density adjustable from 1 to 10$\times10^{14}$\,cm$^{-3}$ [...]

We summarize and explain the realization of witness particle injection into wakefields for the AWAKE experiment. In AWAKE, the plasma wakefields are driven by a self-modulating relativistic 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 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. [...]

Seeding self-modulation of a long proton bunch with a short electron bunch / Muggli, P. (Munich, Max Planck Inst.) ; Morales Guzman, P.I. (Munich, Max Planck Inst. ; Munich, Tech. U.) ; Bachmann, A.-M. (Munich, Max Planck Inst. ; CERN ; Munich, Tech. U.) ; Hüther, M. (Munich, Max Planck Inst.) ; Moreira, M. (CERN ; IST, Lisbon (main)) ; Turner, M. (CERN) ; Vieira, J. (IST, Lisbon (main))
We briefly compare in numerical simulations the relativistic ionization front and electron bunch seeding of the self-modulation of a relativistic proton bunch in plasma. When parameters are such that initial wakefields are equal with the two seeding methods, the evolution of the maximum longitudinal wakefields along the plasma are similar. [...]

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. [...]

The AWAKE Run 2 programme and beyond / AWAKE Collaboration
Plasma wakefield acceleration is a promising technology to reduce the size of particle accelerators. Use of high energy protons to drive wakefields in plasma has been demonstrated during Run 1 of the AWAKE programme at CERN. [...]

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. [...]
