Launch scenarios for electron-cyclotron power into TIBER-II equilibria are presented. The power is absorbed outside the q = 2 flux surface, and the driven current significantly modifies the current profile, which may serve to suppress tearing-mode instabilities and prevent disruptions. A feedback-stabilization scheme may suppress the instabilities with very modest incident power. One of the launch scenarios is also effective for heating the plasma core during the startup phase. 15 refs., 4 figs.
