Accurate modeling of plasma acceleration with arbitrary order pseudo-spectral particle-in-cell methods
Sören Jalas, Irene Dornmair, Rémi Lehe +4
Particle in Cell (PIC) simulations are a widely used tool for the investigation of both laser- and beam-driven plasma acceleration. It is a known issue that the beam quality can be…
Pseudo-spectral Maxwell solvers for an accurate modeling of Doppler harmonic generation on plasma mirrors with Particle-In-Cell codes
G. Blaclard, H. Vincenti, R. Lehe +1
With the advent of PW class lasers, the very large laser intensities attainable on-target should enable the production of intense high order Doppler harmonics from relativistic las…
Elimination of Numerical Cherenkov Instability in flowing-plasma Particle-In-Cell simulations by using Galilean coordinates
Remi Lehe, Manuel Kirchen, Brendan B. Godfrey +2
Particle-In-Cell (PIC) simulations of relativistic flowing plasmas are of key interest to several fields of physics (including e.g. laser-wakefield acceleration, when viewed in a L…
Stable discrete representation of relativistically drifting plasmas
Manuel Kirchen, Remi Lehe, Brendan B. Godfrey +5
Representing the electrodynamics of relativistically drifting particle ensembles in discrete, co-propagating Galilean coordinates enables the derivation of a Particle-in-Cell algor…
ASCR/HEP Exascale Requirements Review Report
Salman Habib, Robert Roser, Richard Gerber +51
This draft report summarizes and details the findings, results, and recommendations derived from the ASCR/HEP Exascale Requirements Review meeting held in June, 2015. The main conc…
An efficient and portable SIMD algorithm for charge/current deposition in Particle-In-Cell codes
H. Vincenti, R. Lehe, R. Sasanka +1
In current computer architectures, data movement (from die to network) is by far the most energy consuming part of an algorithm (10pJ/word on-die to 10,000pJ/word on the network).…
