Abstract

The objective of this research is to determine the scaling of the plasma's radial transport with asymmetry amplitude. The experiment was performed by applying an asymmetric potential to the various wall sectors of the confinement region of the trap and measuring the resulting change in transport. The transport data was taken at particular asymmetry frequencies over a range of applied asymmetry amplitudes for various radii. The current transport theory predicts two regimes, plateau and banana, at which the transport should scale at values of two and one-half, respectively. The banana regime was never observed, but our data generally agreed with plateau regime theory for various radii at low asymmetry amplitudes. However, we also observed several cases where the transport scaled near a value of one.These cases appear to be characterized by an induced transport that is equal in magnitude, but opposite in sign to the background transport.
