摘要: Two techniques are applied and the results compared both in plasma core edge region of “Thorello,” to estimate electron temperature fluctuations. The first method is a fast-sweep Langmuir probe: it new apparatus based on dual channel circuit that compensates for stray capacitance permits sweep speeds up 400 kHz, so we can investigate electrostatic turbulence with good temporal resolution. second technique conventional triple this allows us measure density, temperature, floating potential as function time. probe provides more reliable fluctuations these measurements essential correct interpretation density
