| Summary: | A Hall eect plasma thruster acceleration channel walls was numerically
modeled using 2D3V Particle-in-Cell (PIC) and Monte-Carlo Collision (MCC)
methodologies. Electron, ion, and neutral dynamics were treated kinetically on
the electron time scale to study transport and the electron energy distribution
function. Axisymmetric R-Z coordinates were used with a non-orthogonal
variable mesh to account for important small-scale plasma structures and a
complex physical geometry. The simulation included, via MCC, elastic and
inelastic electron-neutral collisions and ion-neutral scattering and charge exchange
collisions. The cathode was modeled indirectly by injecting electrons at
a rate which conserved the number of electrons through anode. Free space permittivity
was increased to allow a coarser grid and longer time-step. A method
for changing the ion to electron mass ratio and retrieving physical results was
developed and used throughout. Results were compared with analytic and
experiments. |
