Bright X-ray radiation from plasma bubbles in an evolving laser wakefield accelerator
M. S. Bloom, M. J. V. Streeter, S. Kneip +17
We show that the properties of the electron beam and bright x-rays produced by a laser wakefield accelerator can be predicted if the distance over which the laser self-focuses and…
Observation of Laser Power Amplification in a Self-Injecting Laser Wakefield Accelerator
M. J. V. Streeter, S. Kneip, M. S. Bloom +17
We report on the depletion and power amplification of the driving laser pulse in a strongly-driven laser wakefield accelerator. Simultaneous measurement of the transmitted pulse en…
Local up-down asymmetrically shaped equilibrium model for tokamak plasmas
Paulo Rodrigues, André Coroado
A local magnetic equilibrium model is presented, with finite aspect ratio and up-down asymmetrically shaped cross section, that depends on eight free parameters. In contrast with o…
Conditions for the onset of the current filamentation instability in the laboratory
N. Shukla, J. Vieira, P. Muggli +3
Current Filamentation Instability (CFI) is capable of generating strong magnetic fields relevant to explain radiation processes in astrophysical objects and lead to the onset of pa…
Interaction between electrostatic collisionless shocks generates strong magnetic fields
E. Boella, K. Schoeffler, N. Shukla +3
The head-on collision between electrostatic shocks is studied via multi-dimensional Particle-In-Cell simulations. It is found that the shock velocities drop significantly and a str…
Ion acceleration in electrostatic collisionless shock: on the optimal density profile for quasi-monoenergetic beams
E. Boella, F. Fiúza, A. Stockem Novo +2
A numerical study on ion acceleration in electrostatic shock waves is presented, with the aim of determining the best plasma configuration to achieve quasi-monoenergetic ion beams…
A Drift-Kinetic Analytical Model for SOL Plasma Dynamics at Arbitrary Collisionality
R. Jorge, P. Ricci, N. F. Loureiro
A drift-kinetic model to describe the plasma dynamics in the scrape-off layer region of tokamak devices at arbitrary collisionality is derived. Our formulation is based on a gyroav…
AWAKE readiness for the study of the seeded self-modulation of a 400\,GeV proton bunch
P. Muggli, E. Adli, R. Apsimon +104
AWAKE is a proton-driven plasma wakefield acceleration experiment. % We show that the experimental setup briefly described here is ready for systematic study of the seeded self-mod…
The fully kinetic Biermann battery and associated generation of pressure anisotropy
K. M. Schoeffler, N. F. Loureiro, L. O. Silva
The dynamical evolution of a fully kinetic, collisionless system with imposed background density and temperature gradients is investigated analytically. The temperature gradient le…
Comparison between measured and predicted turbulence frequency spectra in ITG and TEM regimes
J. Citrin, H. Arnichand, J. Bernardo +6
The observation of distinct peaks in tokamak core reflectometry measurements - named quasi-coherent-modes (QCMs) - are identified as a signature of Trapped-Electron-Mode (TEM) turb…
Coherent -pulse emitted by a dense relativistic cold electron beam
J. A. Arteaga, L. F. Monteiro, A. Serbeto +2
Starting from a three-wave interaction system of equations for free-electron lasers in the framework of a quantum fluid model, we show that these equations satisfy the Sine-Gordon…
Mitigation of the hose instability in plasma-wakefield accelerators
T. J. Mehrling, R. A. Fonseca, A. Martinez de la Ossa +1
Current models predict the hose instability to crucially limit the applicability of plasma-wakefield accelerators. By developing an analytical model which incorporates the evolutio…
