A new electrostatic Particle-in-Cell with Monte Carlo Collisions code with adaptive Cartesian mesh (ES-PIC-ACM) has been developed for simulation of low temperature plasmas. ESPIC-ACM has been validated for Capacitively Coupled Plasmas (CCPs) using the simplest firstorder accurate nearest grid point (NGP) technique and more accurate cloud-in-cell (CIC) methods. We have confirmed that the accura...

Abstract A comparative simulation of the generation and acceleration runaway electrons in discharge gap during initiation by nanosecond subnanosecond pulses is carried out. We used a numerical model based on PIC-MCC method. Calculations were out for N 2 6 atm pressure. Numerical formation process electron avalanche initiated an field-emitted from top cathode microspike was taking into account m...

Hall thruster is a kind of plasma optics device, which used mainly in space propulsion. To study the influence magnetic field on performance 5 kW hall thruster, two-dimensional PIC-MCC model was built. The Bohm diffusion modeled by using Brownian motion instead collision method and near-wall conduction secondary electron emission model. When mass flow rate mg/s, like thrust, efficiency discharg...

Using 2D particle-in-cell (PIC) simulations coupled to a fluid description of the gas dynamics, we study electrostatic instabilities developing in axial–azimuthal plane Hall thruster, during several periods low-frequency oscillation (the so-called breathing mode at [Formula: see text]). As done experiments, PIC-MCC (Monte Carlo collision) code is an electrical circuit order partially damp (othe...

The oopd1 particle-in-cell Monte Carlo collision (PIC-MCC) code is used to simulate a capacitively coupled discharge in oxygen. oopd1 is a one-dimensional object-oriented PIC-MC code in which the model system has one spatial dimension and three velocity components. It contains a model for planar geometry and will contain models for cylindrical and spherical geometries, and replaces the xpdx1 se...

In this article, performance limitations of the particle advance in a particle-in-cell (PIC) simulation are discussed. It is shown that the memory subsystem and cache-thrashing severely limit the speed of such simulations. Methods to implement a PIC simulation under such conditions are explored. An algorithm based on a counting sort is developed which effectively eliminates PIC simulation cache...

A novel Immersed-Finite-Element Particle-in-Cell (IFE-PIC) simulation tool is presented in this paper for plasma surface interaction where charged plasma particles are represented by a number of simulation particles. The Particle-in-Cell (PIC) method is one of the major particle models for plasma simulation, which utilizes a huge number of simulation particles and hence provides a first-princip...
