Elevating electron energy gain and betatron X-ray emission in proton-driven wakefield acceleration

Hossein Saberi, Guoxing Xia, Linbo Liang +2

The long proton beams present at CERN have the potential to evolve into a train of microbunches through the self-modulation instability process. The resonant wakefield generated by…

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…

Acceleration of an electron bunch with a non-Gaussian transverse profile in a quasilinear plasma wakefield

Linbo Liang, Guoxing Xia, Alexander Pukhov +1

Beam-driven plasma wakefield accelerators typically use the external injection scheme to ensure controllable beam quality at injection. However, the externally injected witness bun…

The AWAKE Run 2 programme and beyond

Edda Gschwendtner, Konstantin Lotov, Patric Muggli +99

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…

Simulation study of betatron radiation in AWAKE Run 2 experiment

Linbo Liang, Guoxing Xia, Hossein Saberi +2

The spectroscopy of betatron radiation from the focusing plasma column can work as a powerful non-invasive beam diagnostic method for plasma wakefield acceleration experiments such…

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…

Injection tolerances and self-matching in a quasilinear wakefield accelerator

John P. Farmer, Linbo Liang, Rebecca Ramjiawan +4

Particle acceleration in a quasilinear plasma wake provides access to high acceleration gradients while avoiding self-trapping of the background electrons. However, the plasma resp…

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…

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…

Experimental study of extended timescale dynamics of a plasma wakefield driven by a self-modulated proton bunch

J. Chappell, E. Adli, R. Agnello +96

Plasma wakefield dynamics over timescales up to 800 ps, approximately 100 plasma periods, are studied experimentally at the Advanced Wakefield Experiment (AWAKE). The development o…

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…
