Density and Particle Sourcing Optimization in a Helicon Plasma Source Prototype For Wakefield Accelerator Applications
Michael Zepp, Marcel Granetzny, Oliver Schmitz
Helicon plasmas are being considered as plasma sources for wakefield accelerators, subject to strict density requirements. We present various mechanisms to increase axial density h…
Exploration of Helicon Plasmas for Wakefield Accelerators at the Madison AWAKE Prototype
Marcel Granetzny, Barret Elward, Michael Zepp +2
Plasma wakefield accelerators have the potential to revolutionize particle physics by providing lepton collision energies orders of magnitude beyond current technology. Crucially,…
Preference of Right-Handed Whistler Modes and Helicon Discharge Directionality due to Plasma Density Gradients
Marcel Granetzny, Oliver Schmitz, Michael Zepp
Whistlers are magnetized plasma waves in planetary magnetospheres. Bounded whistlers, known as helicons, can create high-density laboratory plasmas. We demonstrate reversal of the…
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 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 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…
