Filamentation of a Relativistic Proton Bunch in Plasma
L. Verra, C. Amoedo, N. Torrado +12
We show in experiments that a long, underdense, relativistic proton bunch propagating in plasma undergoes the oblique instability, that we observe as filamentation. We determine a…
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…
Techniques to seed the self-modulation instability of a long proton bunch in plasma
L. Verra, G. Zevi Della Porta, E. Gschwendtner +2
The Advanced Wakefield Experiment (AWAKE) at CERN relies on the seeded Self-Modulation (SM) of a long relativistic proton bunch in plasma to accelerate an externally injected MeV w…
Focusing of a Long Relativistic Proton Bunch in Underdense Plasma
Livio Verra, Edda Gschwendtner, Patric Muggli
We discuss the focusing effect experienced by a long relativistic proton bunch, when propagating in underdense plasma. We show with 2D quasi-static simulations that the response of…
