Hybrid drift-kinetic electron/full kinetic ion PIC simulation of RF plasma discharge in magnetic mirror machine
POSTER
Abstract
We present numerical simulations of a radio-frequency- (RF-) induced plasma discharge in magnetic mirror machines, with relevance to Electron Cyclotron Ion Source (ECRIS) devices. The simulations are done in 2D cylindrically symmetric geometry. The code \textbf{SIMPL} is a PIC code, which uses drift-kinetic electron and full kinetic ion description. The RF wave heating is implemented as a ``kick'' model, i.e., electrons get an increment in their perpendicular velocity when they cross the magnetic resonance surface. Atomic physics is for Argon and includes the following basic reactions: single ionization by electron impact, excitation, elastic scattering, and charge exchange. We will discuss the steady-state spatial structure of the discharge.
