Seeding of Self-Modulation using Truncated Seed Bunches as a Path to High Gradient Acceleration
N. Z. van Gils, E. Belli, M. Bergamaschi +11
This manuscript proposes a method to enable controlled high-gradient particle acceleration when requiring self-modulation of the drive bunch. While electron bunch seeding of self-m…
Measurement of the Saturation Length of the Self-Modulation Instability
A. Clairembaud, M. Turner, M. Bergamaschi +8
The self-modulation (SM) instability transforms a long charged particle bunch traveling in plasma into a train of microbunches that resonantly drives large-amplitude wakefields. We…
Experimental Observation of Motion of Ions in a Resonantly Driven Plasma Wakefield Accelerator
M. Turner, E. Walter, C. Amoedo +15
We show experimentally that an effect of motion of ions, observed in a plasma-based accelerator, depends inversely on the plasma ion mass. The effect appears within a single wakefi…
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…
