Ion cyclotron range of frequencies (ICRFs) have been proven to efficiently serve as a toroidal rotation source in tokamak plasmas. Recent experiments show that the change in internal inductance (l (i)) significantly modifies the rotation profiles and affects the ion and electron temperature profiles.
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.
