→Can anomalous transport be controlled?

The impression is that anomalous transport is more difficult to control in tokamaks than in stellarators. However, limited control in tokamaks is possible by making use of edge transport barriers (cf. [[H-mode]]) and [[Internal Transport Barrier]]s (ITBs). This reduces transport to Neoclassical levels, at least transiently. | The impression is that anomalous transport is more difficult to control in tokamaks than in stellarators.
