内容記述タイプ | Abstract | |||||
内容記述 | 超伝導トカマク装置ではトロイダル磁場がショット間にも存在するため,ショット間に壁調整放電を行うには電子サイクロトロン(EC)波の入射による短パルスのプラズマ放電を繰り返す手法(ECWC)が有望である.本研究では,韓国核融合エネルギー研究所の超伝導トカマク装置KSTARでECWCによる重水素脱ガス量のパラメータ依存性を調べた.ECの入射パルス幅,入射パワーおよびヘリウムガス圧の増加に伴ってECWCプラズマ密度の増加が観測された.また,EC入射パワーが大きいほど重水素の脱ガス量が増加するが,ヘリウムガス圧が高すぎると重水素の脱ガス量は減少するとことが観測された. | |||||
