Abstract
Experiments in the tandem mirror TMX-U reveal three significant sources of nonambipolar radial transport associated with resonant transport in the central cell and, in the end cells, with electron cyclotron heating and neutral beam heating. A simple model suggests that the electron-cyclotron-heating–induced transport is due to the asymmetric application of power. This transport mechanism is important because it applies even in axisymmetric magnetic geometries.
