Measurement of the emittance of accelerated electron bunches at the AWAKE experiment
D. A. Cooke, F. Pannell, G. Zevi Della Porta +81
The vertical plane transverse emittance of accelerated electron bunches at the AWAKE experiment at CERN has been determined, using three different methods of data analysis. This is…
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…
Automatic setup of 18 MeV electron beamline using machine learning
Francesco Maria Velotti, Brennan Goddard, Verena Kain +3
To improve the performance-critical stability and brightness of the electron bunch at injection into the proton-driven plasma wakefield at the AWAKE CERN experiment, automation app…
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…
Study of alternative locations for the SPS Beam Dump Facility
Oliver Aberle, Claudia Ahdida, Pablo Arrutia +26
As part of the main focus of the BDF Working Group in 2021, this document reports on the study of alternative locations and possible optimisation that may accompany the reuse of ex…
Design of the AWAKE Run 2c transfer lines using numerical optimizers
Rebecca Ramjiawan, Vittorio Bencini, Steffen Doebert +5
The Advanced Wakefield (AWAKE) Experiment is a proof-of-principle experiment demonstrating the acceleration of electron beams via proton-driven plasma wakefield acceleration. AWAKE…
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…
A high-resolution, low-latency, bunch-by-bunch feedback system for nano-beam stabilization
D. R. Bett, N. Blaskovic Kraljevic, T. Bromwich +4
We report the design, operation and performance of a high-resolution, low-latency, bunch-by-bunch feedback system for nano-beam stabilisation. The system employs novel, ultra-low q…
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…
