Abstract
The robustness of a feedback stabilization scheme using a feedback-modulated beam as a remote suppressor applied to a single plasma instability is investigated. The fluctuation level induced by the instability and its growth rate can be varied by changing experimental control parameters. The principal result is that the feedback scheme is robust, and that the robustness window can be increased by increasing the feedback gain
