Neutral particle emission of the pulsator plasma during high-density discharges
Abstract
Experimentally determined absolute values of the fast hydrogen flux are compared with the predictions of a 6-regime-transport code. Remarkable agreement is obtained. By varying the location of the pulsed gas inlet it was shown that the emitted flux decays markedly with toroidal distance from the position of the gas inflow by an amount which is fairly independent of particle energy. Radial profiles of ion temperature and particle flux show a high degree of symmetry. The observed ion temperature at the plasma edge is 190 eV which is attributed to a considerable number of fast neutrals which are reflected from the container wall.
