Abstract

Measurements of edge plasma turbulence properties have been carried out in the Advanced Toroidal Facility (ATF) [Fusion Technol. 10, 179 (1986)] during experiments in which hydrogen and neon gas puffing are used to vary the edge temperature in the range 5 < T_e < 40 eV in a controlled way. In the temperature range where the rate coefficients for ionization processes are strongly temperature dependent (5 < T_e < 15 eV) the electron temperature plays an important role in determining the level of edge turbulence and the value of the self-generated radial electric fields. These results provide evidence of edge turbulence and flows modified by the presence of neutral particles.
