Abstract
The use of radio frequency waves in the ion cyclotron range of frequencies is shown to stabilize ballooning modes in tokamaks when the frequency and spatial wave structure are appropriately chosen. The physics of rf stabilization may provide access to high- tokamak operation in the second stability regime and may also be useful in the suppression of edge-localized modes in present experiments. Estimates of the required power in the ion cyclotron range of frequencies are given for two examples of rf stabilization.
