Abstract :
Summary form only given. The 2-D multifluid implicit simulation code ANTHEM was used to model the plasma flow switch. The code treats a background ion fluid and both a background and an emission electron fluid. Electron inertia and collisions are retained, and the full Maxwell equations are solved. The 500-ns period of commutation is treated when the electron flow, is diverted from the drive plasma to the T walls and the load. The effects of (1) Child-Langmuir wall emission, (2) plasma fringing into the stem. (3) Hall currents, (4) nonlinear advective magnetic field penetration, and (5) vacuum line EM wave transmission on switching of the power to the load were investigated
