Generation of 10-m-lengthscale plasma columns by resonant and off-resonant laser pulses
G. Demeter, J. T. Moody, M. A. Kedves +7
Creating extended, highly homogeneous plasma columns like that required by plasma wakefield accelerators can be a challenge. We study the propagation of ultra-short, TW power ioniz…
Mapping charge capture and acceleration in a plasma wakefield of a proton bunch using variable emittance electron beam injection
E. Granados, L. Verra, A. -M. Bachmann +10
In the Phase 2 of the AWAKE first experimental run (from May to November 2018), an electron beam was used to probe and test proton-driven wakefield acceleration in a rubidium plasm…
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…
Machine learning methods for Schlieren imaging of a plasma channel in tenuous atomic vapor

We investigate the usage of a Schlieren imaging setup to measure the geometrical dimensions of a plasma channel in atomic vapor. Near resonant probe light is used to image the plas…
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…
