A novel scheme for the control of major disruptions in tokamaks via feedback suppression of kink-kink{endash}ballooning modes is proposed. The scheme consists of a modulated neutral beam suppressor in a feedback loop, which supplies a momentum input of appropriate phase and magnitude. Simple theoretical models predict modest levels of beam energy, current, and power for typical tokamaks, and extrapolability of the scheme to tokamak reactors is indicated. {copyright} {ital 1996 The American Physical Society.}
