Results are presented from an experiment in which a large amount of deuterium gas was continuously puffed at the scrape-off layer and exhausted from the DIII-D pump divertor ('puff and pump' technique). The experiments were conducted with a single null divertor configuration during edge localized mode (ELM)ing H mode. Steady state density conditions were attained during the strong deuterium puff. The deuterium puff reduced the central plasma density of argon, puffed continuously as a trace impurity, by as much as a factor of 20, and the central argon radiated power density by as much as a factor of 10

大量の重水素ガスをスクレイプオフ層に連続的に噴射し、DIII-Dポンプダイバータから排気する実験(「パフ・アンド・ポンプ」法)の結果を提示する。実験は、ELM(周辺局在モード)を伴うHモード中に、シングルヌルダイバータ配位で実施された。強い重水素パフ中に、定常状態の密度条件が達成された。この重水素パフにより、微量不純物として連続的に噴射されたアルゴンの中心プラズマ密度は最大20分の1に、中心部のアルゴン放射パワー密度は最大10分の1に減少した。
