Abstract
We have measured fast magnetic fluctuations (> 10 kHz) using a complex edge probe in the edge region of TPE-RX reversed-field pinch plasma. We observed that the frequency of magnetic fluctuation at the peak power in the frequency spectrum varies with time, and this frequency variation is determined by the values of pinch and reversed parameters, although the amplitude of the fast magnetic fluctuations are almost independent of those parameter values.
