The condition for stabilizing the universal drift mode by superimposing an external high-frequency Trivelpiece-Gould mode is investigated based on a new mode-coupling process (plasma-maser effect). The energy up-conversion from the universal drift mode to the high-frequency rf field stabilizes the low-frequency drift mode. Under suitable conditions, the new method based on plasma-maser interaction is effective at a smaller relative magnitude of the rf field than the one based on a ponderomotive force in a narrow sense.
