Electron cyclotron heating experiments in the DIII-D tokamak

OSTI ID:6759316
Electron cyclotron heating (ECH) experiments in the DIII-D tokamak have been performed at power levels around 1 MW using outside launch of both the extraordinary and ordinary mode, and inside launch of the extraordinary mode. Effective plasma heating has been obtained, with central electron temperatures up to 5 keV. In addition to simple bulk heating, the localized nature of ECH has been used to obtain the H-mode, to suppress internal disruptions (sawteeth), and to suppress MHD activity at the plasma edge. Suppression of Edge Localized Modes results in a clear improvement of the confinement properties of the H-mode, with the improvement manifested in both density and electron temperature. 16 refs., 2 figs.
