Abstract

Experimental data of the energy spectrum of the flux of neutral hydrogen emitted during discharges in TORTUR II have been modelled using a kinetic code to describe the neutral particle dynamics. Various assumptions on the characteristics of particle recycling from the wall were compared, adopting analytic profiles for the plasma density and the temperature of ions and electrons. As a result, the experimental results are best reproduced when it is assumed that the neutral particle flux from the wall has low energy (in the eV range) and that there is a cool and dense plasma layer in the edge region.
