The spatial transition behaviour of the electron gas on its way from a uniform activeplasma through an adjacent region of field decay and reversal into a field-free remoteplasma is studied in neon on a nonlocal kinetic basis by solving the appropriate electronBoltzmann equation and by performing complementary Monte Carlo simulations. The main objective of the analysis concerns the complex features of the electron gas in itstransition process from a field-driven active plasma, through a range of partialelectron trapping in a potential energy valley to a diffusion-driven remote plasma. In this context especially the influence of the electron trapping andof the extent and depth of the potential valley is elaborated. In addition tothe macroscopic characterization by means of the important transport anddissipation properties of the electronstheir energy space resolved behaviour is derived and interpreted. A distinct decoupling between the spatial evolution of the isotropic and anisotropic partof the velocity distribution function and complex structures in the anisotropic parthave been found. These findings could be clearly confirmed by the almost perfectcoincidence with corresponding results obtained by the MC simulations. Glow; corona
