Observation of the H-mode in Ohmically heated divertor discharges on DIII-D

  • 1. General Atomics, San Diego, CA (USA)

Description

On DIII-D, periods of improved particle and energy confinement have been observed in low q, low BT, divertor discharges with Ohmic heating alone. The Ohmic H-mode has characteristics similar to those of the H-mode produced by auxiliary heating. In the Ohmic H-mode the energy confinement time can have values near those predicted by Neo-ALCATOR scaling and a factor of two above those of non-H-mode Ohmic discharges at similar densities. These observations indicate that H-mode is not limited to an improvement in confinement over that of the L-mode in auxiliary heating discharges. (author). 26 refs, 7 figs
