Hosing of a long relativistic particle bunch in plasma
T. Nechaeva, L. Verra, J. Pucek +4
Experimental results show that hosing of a long particle bunch in plasma can be induced by wakefields driven by a short, misaligned preceding bunch. Hosing develops in the plane of…
Development of the Self-Modulation Instability of a Relativistic Proton Bunch in Plasma
L. Verra, S. Wyler, T. Nechaeva +7
Self-modulation is a beam-plasma instability that is useful to drive large-amplitude wakefields with bunches much longer than the plasma skin depth. We present experimental results…
Controlled Growth of the Self-Modulation of a Relativistic Proton Bunch in Plasma
L. Verra
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…
Analysis of Proton Bunch Parameters in the AWAKE Experiment
V. Hafych, A. Caldwell, R. Agnello +85
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…
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…
Witness electron beam injection using an active plasma lens for a proton beam-driven plasma wakefield accelerator
S. -Y. Kim, K. Moon, M. Chung +7
An active plasma lens focuses the beam in both the horizontal and vertical planes simultaneously using a magnetic field generated by a discharge current through the plasma. A beam…
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…
Proton beam defocusing in AWAKE: comparison of simulations and measurements
A. A. Gorn, M. Turner, E. Adli +96
In 2017, AWAKE demonstrated the seeded self-modulation (SSM) of a 400 GeV proton beam from the Super Proton Synchrotron (SPS) at CERN. The angular distribution of the protons defle…
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…
Experimental Study of Wakefields Driven by a Self-Modulating Proton Bunch in Plasma
M. Turner, P. Muggli, the 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' growt…
AWAKE readiness for the study of the seeded self-modulation of a 400\,GeV proton bunch
P. Muggli, E. Adli, R. Apsimon +104
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-mod…
