Abstract

Studies of RF heated PLT discharges have been performed using Langmuir probes and combined electrostatic calorimeter probes. In addition to the usual conductive and convective losses in the edge, evidence is found for the presence of a substantial group of fast ions having energies in the ≈10⁵ eV range. Such ions are present in the cases of H⁺ minority and H⁺ 2nd harmonic heating, however, no such group has been observed in ³He minority heating. The data are presented with calculations to estimate the velocity space distributions of these ions.
