The resistive-wall-mode is an instability that limits the optimum operation of tokamak plasmas used in fusion energy research. The identification of such dangerous modes at the on-set of instability is one of the key issues for higher performance operation. This project will develop computational technology to identify the rotation, phase, and structure of resistive-wall-modes in real time; if the onset of the instability can be identified, the technology can be used in plasma feedback control. In Phase I, a computational tool will be developed for resistive-wall-mode identification of mode-rotation, phase, and structure at the probe location. The identification algorithm will be optimized for real-time analysis, which will take place in Phase II along with a demonstration of its capability to control tokamak plasma instabilities.

Commercial Applications and Other Benefits as described by the awardee: The computational tool that identifies the resistive-wall-mode in real time should be an essential component of any system for controlling these instabilities. Such a tool would play a large role in the success of the tokamak as a future fusion energy source. The completed package with visualization also could be used as an education tool and has application to other visualization software development.
