GEMPIC: geometric electromagnetic particle-in-cell methods [PDF]

Journal of Plasma Physics, 2016
We present a novel framework for finite element particle-in-cell methods based on the discretization of the underlying Hamiltonian structure of the Vlasov–Maxwell system. We derive a semi-discrete Poisson bracket, which retains the defining properties of

A polynomial particle-in-cell method [PDF]

ACM Transactions on Graphics, 2017
Recently the Affine Particle-In-Cell (APIC) Method was proposed by Jiang et al.[2015; 2017b] to improve the accuracy of the transfers in Particle-In-Cell (PIC) [Harlow 1964] techniques by augmenting each particle with a locally affine, rather than locally constant description of the velocity.

The energy conserving particle-in-cell method [PDF]

Journal of Computational Physics, 2011
A new particle-in-cell (PIC) method, that conserves energy exactly, is presented. The particle equations of motion and the Maxwell’s equations are differenced implicitly in time by the midpoint rule and solved concurrently by a Jacobian-free Newton ...

Particle-In-Cell Simulation Using Asynchronous Tasking [PDF]

, 2021
Recently, task-based programming models have emerged as a prominent alternative among shared-memory parallel programming paradigms. Inherently asynchronous, these models provide native support for dynamic load balancing and incorporate data flow concepts to selectively synchronize the tasks.

Numerical Aspects of Particle-in-Cell Simulations for Plasma-Motion Modeling of Electric Thrusters

Aerospace, 2021
The present work is focused on a detailed description of an in-house, particle-in-cell code developed by the authors, whose main aim is to perform highly accurate plasma simulations on an off-the-shelf computing platform in a relatively short ...

EMPIRE-PIC: A Performance Portable Unstructured Particle-in-Cell Code

Communications in Computational Physics, 2021
. In this paper we introduce EMPIRE-PIC, a finite element method particle-in-cell (FEM-PIC) application developed at Sandia National Laboratories. The code has been developed in C++ using the Trilinos library and the Kokkos Performance Portability ...

Laser-driven production with advanced targets of Copper-64 for medical applications

Frontiers in Physics, 2023
Radionuclides are of paramount importance in nuclear medicine both for clinical uses and radiopharmaceutical production. Among the others, nuclides suitable for theranostics like Copper-64 are particularly attractive since they can play both a diagnostic

Particle in Cell Simulation [PDF]

International Journal of Applied Physics and Mathematics, 2012
Aim of this work is particle system simulation by the new programming language therefore we reviewed several methods for simulation of plasma systems. The particle-in-cell (PIC) method is then applied on a simple plasma system. In the PIC method ions are considered as a neutral-stationary background where electrons move around their initially occupied ...

Study on the influence of magnetic field on the performance of a 5 kW hall thruster

Frontiers in Materials, 2023
Hall thruster is a kind of plasma optics device, which is used mainly in space propulsion. To study the influence of magnetic field on the performance of a 5 kW hall thruster, a two-dimensional PIC-MCC model was built.
