Interaction between turbulence and a nonlinear tearing mode in the low {beta} regime
- Institute for Fusion Studies, University of Texas at Austin, Austin, Texas 78712 (United States)
The interaction between turbulence and a nonlinear tearing mode is investigated numerically using a 2D electrostatic model. Turbulence is found to cause transitions between the different roots for the propagation velocity of the mode. The transitions take the mode towards roots with slower propagation that are characterized by a locally flattened density profile. For sufficiently large islands the transition reduces the drive for the tearing mode.
