Abstract
A two-point model for plasma transport along divertor field lines is presented here. Solutions for the steady-state plasma temperature, density, and flow speed at the divertor throat and plate are found for a given throat heat flux, divertor field line length, neutral recycling coefficient, and throat density. Because of the simplicity of the model, it is useful for parameter surveys and indications of general trends. Results from the model show that more than one steady-state solution can exist for a particular throat density and that the range of throat densities for which solutions exist is limited. Also, for a constant plasma flux at the divertor throat, as neutral recycling increases, the throat density must also increase to compensate for a large decrease in plasma flow speed at the throat.
