Abstract
Theory and computations for a wall-confined slow-liner-compressed plasma are presented. The liner device considered has axial open-ended field lines. The numerical calculations include cross-field diffusion of magnetic field, heat, and impurities; compressional effects; heat loss to materially plugged ends; and radiation loss (including coronal impurity radiation). Both insulating and conducting liner boundary conditions are treated. The formation of a cold dense boundary layer is particularly severe in the former case. The heat transport is treated classically with some comparison to possible anomalous behaviour. While impurities are driven out of a straight high-β plasma by thermal forces, critical trace level amounts present at injection can be catastrophic. Some simple scaling laws for various loss mechanisms are given.
