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…

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…

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…
