Abstract

Abstract: Ion cyclotron range of frequencies (ICRFs) have proven to efficiently serve as a toroidal rotation source in tokamak plasmas. Recent experiments on the experimental advanced superconducting tokamak show that the rotation profiles are remarkably modified when the internal inductance ( l i ) changed. The comparisons of the ion and electron temperature profiles among ICRF-heated plasmas suggest that the change in l i can remarkably affect the toroidal rotation velocity. The scaling of rotation velocity increments as a function of the change in l i also suggests that ICRF would serve as a reliable rotation source in plasmas with larger l i decrements.
