Macroparticles with different weights relax to different temperatures in Particle-In-Cell simulations
Remi Lehe, Arianna Formenti, Justin R. Angus +1
A distinctive feature of Particle-In-Cell (PIC) simulations is the use of macroparticles, each representing many physical particles. The associated macroparticle weight can vary fr…
Particle-in-Cell Simulations of Burning ICF Capsule Implosions
Johannes J. van de Wetering, Justin R. Angus, W. Farmer +5
Anomalies observed in the neutron spectral shift of high-yield shots at the National Ignition Facility (NIF) suggest the presence of suprathermal ions, implying that kinetic effect…
A Binary Collision Method for Screened Coulomb Collisions in weakly and moderately coupled Plasmas
Justin Ray Angus, Johannes Johgan van de Wetering
A binary-pairing Monte Carlo collision method is presented here for screened Coulomb collisions in plasmas that is valid in the weakly and moderately coupled regimes. The method mo…
Energy-Preserving Coupling of Explicit Particle-In-Cell with Monte Carlo Collisions
Jean-Luc Vay, Justin Ray Angus, Olga Shapoval +3
The Particle-In-Cell (PIC) and Monte Carlo Collisions (MCC) methods are workhorses of many numerical simulations of physical systems. Recently, it was pointed out that, while the t…
Energy-momentum-conserving stochastic differential equations and algorithms for nonlinear Landau-Fokker-Planck equation
Yichen Fu, Justin R. Angus, Hong Qin +1
Coulomb collision is a fundamental diffusion process in plasmas that can be described by the Landau-Fokker-Planck (LFP) equation or the stochastic differential equation (SDE). Whil…
Moment-preserving Monte-Carlo Coulomb collision method for particle codes
Justin Ray Angus, Yichen Fu, Vasily Geyko +2
Binary-pairing Monte-Carlo methods are widely used in particle-in-cell codes to capture effects of small angle Coulomb collisions. These methods preserve momentum and energy exactl…
