AbstractPlasma coupling tests of the RF heating system in JT-60 were successfully performed at JAERI prior to the substantial injection for the plasma heating experiment. About 24 MW LHRF at 2 GHz band and 6 MW ICRF at 120 MHz band system were installed in JT-60. The total system is remotely controlled via a mini-computer, which is linked with the central control system named “ZENKEI” and “CAMAC” systems. The RF power and phase difference can be controlled according to a set preprogram and the plant data can be collected and recorded during RF injection. These are carried out at both LHRF and ICRF injections and simultaneous NBI injection. It is shown that this RF heating system can contribute to both LHRF and ICRF heating experiments for JT-60.

JT-60におけるRF加熱システムのプラズマ結合試験は、プラズマ加熱のための本格的な入射に先立ち、JAERIで成功裏に実施された。約2GHz帯で24MWのLHRFおよび120MHz帯で6MWのICRFシステムがJT-60に設置された。全システムは、「ZENKEI」および「CAMAC」システムと名付けられた中央制御システムにリンクされたミニコンピュータを介して遠隔制御される。RFパワーと位相差は、事前に設定されたプログラムに従って制御でき、RF入射中にプラントデータを収集・記録できる。これらは、LHRFおよびICRFの単独入射と、NBIとの同時入射の両方で実施された。このRF加熱システムが、JT-60のLHRFおよびICRF加熱実験の両方に貢献できることが示された。
