A Simple Scheme for Implementing Wave Absorption in Quasi-Neutral PIC Simulations of ECR Plasma
Abstract
A simple scheme is formulated here for describing the absorption of electron cyclotron waves in ECR plasma reactors. We particularly focus on quasi-neutral particle simulation schemes, where short times like the inverse electron plasma and cyclotron frequencies are not resolved. The formulation here implements a wave kinetic equation for propagation along the magnetic field and the self consistent quasi-linear response of the electrons. The velocity dependence of the wave deposition is correctly described, maxwell electrons are not assumed so the tail of the electron distribution can be either overpopulated or depopulated, depending on the dominant physical processes present. The computer time to solve the problem and the human time to code it up are both minimized.
