POS - A 1D time-dependent H+ ion source code

Abstract
The code POS is based on the first three velocity moment's expansion of the transport equation, as derived in Braginskii's theory for two fully ionized fluids, H^+and e. The theory requires the solution of four (plasma density, drift velocity, electron and ion temperatures) coupled, time-dependent equations. These equations have been solved in one spatial dimension using the method of moving finite elements.

Title of program: POS
Catalogue Id: ABJU_v1_0

Nature of problem
POS is a computer program that predicts the number densities, drift velocities, and electron and ion temperatures of two fluids, e and H+, in a volume ion source, including the effect of a magnetic filter field.
