Novel features of H-mode plasmas induced by edge polarization in TEXTOR

  • 1. Ecole Royale Militaire, Brussels (Belgium). Lab. de Physique des Plasmas

Description

Whereas the energy confinement improvement in H-modes that are characterized by positive radial electric fields in the plasma edge is as good as that of the more usual negative field H-modes, the improvement in particle confinement of main plasma and impurity ions is smaller in the former. Detailed measurements are given of the edge electric field, the electron density and temperature and the electrostatic fluctuation level. During the H-mode an instability can grow that strongly affects the plasma profiles without impairing H-mode behaviour. (author) 6 refs., 5 figs
