Controlled experiments on the suppression of the m/n = 2/1 tearing mode with electron cyclotron heating and current drive in TEXTOR are reported. The mode was produced reproducibly by an externally applied rotating perturbation field, allowing a systematic study of its suppression. Heating inside the island of the mode is shown to be the dominant suppression mechanism in these experiments. An extrapolation of these findings to ITER indicates that the projected system for suppression of the tearing mode could be significantly more effective than present estimates indicate, which only consider the effect of the current drive but not of the heating inside the island.

TEXTORにおける電子サイクロトロン加熱および電流駆動によるm/n = 2/1ティアリングモードの抑制に関する制御実験について報告する。このモードは、外部から印加された回転摂動場によって再現可能に生成され、その抑制の系統的な研究が可能となった。これらの実験において、モードの島内部での加熱が支配的な抑制機構であることが示された。これらの知見をITERに外挿すると、ティアリングモード抑制用に計画されたシステムは、現在の推定値(島内部での加熱ではなく電流駆動の効果のみを考慮している)よりも有意に効果的であり得ることが示唆される。
