Abstract

The amplitudes of electron temperature fluctuations are evaluated in the edge plasma of TST-2 using a new technique. Langmuir probe current-voltage characteristic curves are conditionally reconstituted in terms of the magnitude of the floating potential. High/low electron temperatures are obtained in low/high floatingpotential phases. The relationship between the electron temperature fluctuations and the time-averaged electron temperature gradient is discussed.
