Ion cyclotron heating on TEXTOR has now reached the Megajoule level. The heating scenario is normally mode conversion but occasionally minority heating in a D-(H) plasma. With appropriate wall conditioning by carbonization more than 1 MW of RF power has been injected for long pulse durations ( approximately 1 s). The ICRF heated plasma is characterized by a quasi-stationarity of all plasma parameters, little if no impurity increase and a loop voltage reduction resulting in the total power coupled to the plasma reaching six times the remaining ohmic power input. Evidence of the coupling of the RF power to the plasma is obtained from the increase of the thermal load on the limiters and central energy deposition is supported from analysis of the sawtooth heating rate.

TEXTORにおけるイオンサイクロトロン加熱は、現在メガジュールレベルに達している。加熱シナリオは通常モード変換であるが、D-(H)プラズマでは少数派加熱が起こることもある。カーボン被覆による適切な壁調整により、1MW以上のRFパワーが長時間パルス(約1秒)にわたって入射されている。ICRF加熱プラズマは、全プラズマパラメータの準定常性、不純物増加がほとんどないこと、そしてループ電圧の低減によって特徴づけられ、その結果、プラズマに結合される全パワーはオーミック入力電力の6倍に達する。RFパワーのプラズマへの結合の証拠は、リミッター上の熱負荷の増加から得られ、中心部へのエネルギー堆積は、鋸歯状加熱率の解析から支持されている。
