| Title | 220: Investigation of Alfvenic Activity and Resultant Fast Ion Transport with Low NBI Power | ||

| Description: | The primary goal of this experiment is to investigate the transition in which a well documented discharge used for Alfven eigenmode (AE) studies goes from the regime of classical fast ion transport with weak or no Alfvenic activity to that in which AEs are thought to dominate the fast ion transport. The same series of discharges will also determine typical fast ion betas at which various types of AEs are triggered in DIII-D, the changes in mode structure with drive, and provide data on a new type of Alfvenic fluctuation, the BAAE (Beta Induced Alfven Acoustic Mode). | ||
