Laser absorption via QED cascades in counter propagating laser pulses
Thomas Grismayer, Marija Vranic, Joana L. Martins +2
A model for laser light absorption in electron-positron plasmas self-consistently created via QED cascades is described. The laser energy is mainly absorbed due to hard photon emis…
Study on Coulomb explosions of ion mixtures
E. Boella, B. Peiretti Paradisi, A. D'Angola +2
The paper presents a theoretical work on the dynamics of Coulomb explosion for spherical nanoplasmas composed by two different ion species. Particular attention has been dedicated…
The generation of magnetic fields by the Biermann battery and the interplay with the Weibel instability
K. M. Schoeffler, N. F. Loureiro, R. A. Fonseca +1
An investigation of magnetic fields generated in an expanding bubble of plasma with misaligned temperature and density gradients (driving the Biermann battery mechanism) is perform…
Path to AWAKE: Evolution of the concept
A. Caldwell, E. Adli, L. Amorim +118
This report describes the conceptual steps in reaching the design of the AWAKE experiment currently under construction at CERN. We start with an introduction to plasma wakefield ac…
Quantum radiation reaction in head-on laser-electron beam interaction
Marija Vranic, Thomas Grismayer, Ricardo A. Fonseca +1
In this paper, we investigate the evolution of the energy spread and the divergence of electron beams while they interact with different laser pulses at intensities where quantum e…
Lorentz boosted frame simulation of Laser wakefield acceleration in quasi-3D geometry
Peicheng Yu, Xinlu Xu, Asher Davidson +11
When modeling laser wakefield acceleration (LWFA) using the particle-in-cell (PIC) algorithm in a Lorentz boosted frame, the plasma is drifting relativistically at towards…
The role of MHD in causing impurity peaking in JET Hybrid plasmas
T. C. Hender, P. Buratti, F. J. Casson +10
In Hybrid plasma operation in JET with its ITER-like wall (JET-ILW) it is found that n>1 tearing activity can significantly enhance the rate of on-axis peaking of tungsten impuriti…
Self-modulated laser wakefield accelerators as x-ray sources
N. Lemos, J. L. Martins, F. S. Tsung +5
The development of a directional, small-divergence, and short-duration picosecond x-ray probe beam with an energy greater than 50 keV is desirable for high energy density science e…
Physics of collisionless shocks - theory and simulation
A. Stockem Novo, A. Bret, R. A. Fonseca +1
Collisionless shocks occur in various fields of physics. In the context of space and astrophysics they have been investigated for many decades. However, a thorough understanding of…
Modelling radiation emission in the transition from the classical to the quantum regime
J. L. Martins, M. Vranic, T. Grismayer +3
An emissivity formula is derived using the generalised Fermi-Weizacker-Williams method of virtual photons which accounts for the recoil the charged particle experiences as it emits…
Magnetic reconnection: from the Sweet-Parker model to stochastic plasmoid chains
N. F. Loureiro, D. A. Uzdensky
(abridged) Magnetic reconnection is the topological reconfiguration of the magnetic field in a plasma, accompanied by the violent release of energy and particle acceleration. Recon…
Slow down of a globally neutral relativistic beam shearing the vacuum
E. P. Alves, T. Grismayer, M. G. Silveirinha +2
The microphysics of relativistic collisionless sheared flows is investigated in a configuration consisting of a globally neutral, relativistic beam streaming through a hol…
Transverse electron-scale instability in relativistic shear flows
E. P. Alves, T. Grismayer, R. A. Fonseca +1
Electron-scale surface waves are shown to be unstable in the transverse plane of a shear flow in an initially unmagnetized plasma, unlike in the (magneto)hydrodynamics case. It is…
Viriato: a Fourier-Hermite spectral code for strongly magnetised fluid-kinetic plasma dynamics
N. F. Loureiro, W. Dorland, L. Fazendeiro +4
We report on the algorithms and numerical methods used in Viriato, a novel fluid-kinetic code that solves two distinct sets of equations: (i) the Kinetic Reduced Electron Heating M…
Classical Radiation Reaction in Particle-In-Cell Simulations
Marija Vranic, Joana L. Martins, Ricardo A. Fonseca +1
Under the presence of ultra high intensity lasers or other intense electromagnetic fields the motion of particles in the ultrarelativistic regime can be severely affected by radiat…
Improved Confinement in JET High {beta} Plasmas with an ITER-Like Wall
C. D. Challis, J. Garcia, M. Beurskens +18
The replacement of the JET carbon wall (C-wall) by a Be/W ITER-like wall (ILW) has affected the plasma energy confinement. To investigate this, experiments have been performed with…
