Supersonic gas curtain based real-time ionization profile monitor for hadron therapy
Narender Kumar, Milaan Patel, William Butcher +4
Accurate control and monitoring of the beam is essential for precise dose delivery to tumor tissues during radiotherapy. Real-time monitoring of ion beam profiles and positions imp…
First demonstration of coherent radiation imaging for bunch-by-bunch longitudinal compression monitoring
Joseph Wolfenden, Ana Guisao-Betancur, Carsten Welsch +5
Longitudinal bunch profile monitoring is a crucial diagnostic requirement in most accelerator facilities. This is particularly true in modern free-electron lasers and novel acceler…
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…
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…
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…
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…
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…
