| Abstract: | We analyze the influence of collisions on a plasma column with cylindrical symmetry in the pressure regime between the collision-dominated and the free-fall case. A model is investigated which can handle arbitrary contributions from ion-neutral-collisions. One finds an analytic solution for the ion-distribution-function which depends functionally on the potential. This electrical potential is calculated numerically — with consideration of the space-charge-layer near the wall — and selfconsistently from the Poisson-equation. From the calculation of the ion-distribution-function, of density, flux and temperature of the ions as well as of the potential variation, we discuss the influence of the model parameters. The results are compared with corresponding hydrodynamic calculations. |
