ITER用電子サイクロトロン波(EC),イオンサイクロトロン波(IC),中性ビーム(NB)、そして低域混成波(LH)について、その物理と工学の両面の進展を2007/2008年にレビューした。全体仕様の変更はないものの、以下のような設計変更があった。第一に、DTフェーズの前に全パワーである73MW入射をルーティンに入射可能となるように調整すべきこと。第二に、NBを水素フェーズにもフルパワー入射が可能となるように対向壁を用意する、IC用によりロバスト名アンテナ2式を用意する、またECには2MW容量の伝送系を用意して、増力を容易にする。さらにRF源と計測及び加熱用ポートプラグの試験施設となる付属建屋を用意する。第三に、LHのようにITERの長パルス運転時に適した電流駆動システムを開発するための計画の必要性が認識された。

The electron cyclotron (EC), ion cyclotron (IC), neutral beam (NB) and, lower hybrid (LH) systems for ITER have been reviewed in 2007/2008 in light of progress of physics and technology. Although the overall specifications are unchanged, notable changes have been approved. Firstly, the full 73MW should be commissioned and available on a routine basis before the D/T phase. Secondly, the possibility to operate the NB at full power during the hydrogen phase requiring new shine through protection; IC with 2 antennas with increased robustness; 2 MW transmission systems to provide an easier upgrading of the EC power; the addition of a building dedicated to the RF power sources and to a testing facility for acceptance of diagnostics and heating port plugs. Thirdly, the need of a plan for developing, in time for the active phase, a CD system such as LH suitable for very long pulse operation of ITER was recognized.
