Suppression of sawtooth oscillations by lower-hybrid current drive in the ASDEX tokamak
- 1. Max-Planck-Institut fuer Plasmaphysik, EURATOM Association, D-8046 Garching, Federal Republic of Germany
Description
The sawtooth oscillations in tokamak discharges with Ohmic and neutral-beam heating could be suppressed when a large part of the plasma current was driven by lower-hybrid waves (I/sub HF//I/sub p/≅0.5). The stabilization is due to a flattening of the current profile j(r) and an increase of q(0) above 1. Higher central electron temperatures are obtained with neutral-beam heating if the sawteeth are stabilized. The increase in total energy content in this case was 30% higher than in the presence of sawteeth
