Linear plasma devices with superimposed magnetic field often show nearly Gaussian distributions of charge carrier temperatures and densities. Taking Gaussian distributions as a basis for a zeroth order energy and mass allotment the two-fluid equations can be solved by linearisation. The first order solution delivers the axial, azimuthal and radial velocity components of the electron and ion motion, respectively. These theoretical results are compared with measured data from the LINEX experiment burning in argon under different conditions. Theoretical and experimental data verify that the radial transport of charge carriers derived from the two-fluid theory cannot be explained by classical transport, but is of the same order as Bohm diffusion.
