The major aspects linked to the use of the JET auxiliary heating systems: NBI, ICRF and LHCD, in the new JET ITER-like wall are presented. We show that although there were issues related to the operation of each system, efficient and safe plasma heating was obtained with room for higher power. For the NBI up to 25.7 MW was safely injected; issues that had to be tackled were mainly the beam shine-through and beam re-ionization before its entrance into the plasma. For the ICRF system, 5 MW were coupled in L-mode and 4 MW in H-mode; the main areas of concern were RF sheaths related heat loads and impurities production. For the LH, 2.5 MW were delivered without problems; arcing and generation of fast electron beams in front of the launcher that can lead to high heat loads were the keys issues. For each system, an overview will be given of: the main modifications implemented for safe use, their compatibility with the new metallic wall, the differences in behaviour compared with the previous carbon wall, with emphasis on heat loads and impurity content in the plasma.
JETの新しいITER類似壁におけるJET補助加熱システム、すなわちNBI、ICRF、LHCDの使用に関連する主要な側面について述べる。各システムの運転には問題があったものの、高出力への余裕を残しつつ効率的かつ安全なプラズマ加熱が達成されたことを示す。NBIについては最大25.7 MWが安全に入射され、対処すべき主な問題はビームのシャインスルーと、プラズマへの入射前の再電離であった。ICRFについてはLモードで5 MW、Hモードで4 MWの結合が達成され、主な懸念事項はRFシースに関連する熱負荷と不純物生成であった。LHについては2.5 MWが問題なく入射され、ランチャー前方での高熱負荷につながり得るアーキングと高速電子ビームの生成が主要な課題であった。各システムについて、安全な使用のために実施された主な改良点、新しい金属壁との適合性、従来の炭素壁との挙動の違い、特に熱負荷とプラズマ中の不純物含有量に焦点を当てた概要を示す。
