The electron cyclotron resonance experiment on TFR

TFR Group, FOM ECRH Team1988年被引用 64Nuclear FusionIF 3出版社

A joint Euratom-CEA, Euratom-FOM electron cyclotron resonance heating (ECRH) programme was conducted on the TFR tokamak during 1985 and 1986, with 600 kW of ECR power at 60 GHz. The paper describes the experiments performed during this period and analyses the results. In spite of considerable electron heating, a degradation of the global energy confinement time has been observed in all cases, with incremental confinement times ranging from 1 to 2 ms, depending on the experimental conditions. The electron thermal conductivity has been determined in three different independent ways and the results are in reasonable agreement, but only 1/4-1/3 of the gyrotron power is found in the rate of change of the plasma energy. Other topics addressed are: impurity content and transport, sawtooth behaviour, MHD stabilization, suprathermal electron population and pellet ablation during ECRH.

Euratom-CEAおよびEuratom-FOMによる電子サイクロトロン共鳴加熱(ECRH)プログラムが、1985年から1986年にかけてTFRトカマクにおいて、60GHzで600kWのECRパワーを用いて実施された。本論文では、この期間に行われた実験とその結果の解析について述べる。かなりの電子加熱が観測されたにもかかわらず、全てのケースにおいて全体の閉じ込め時間の劣化が観測され、増分閉じ込め時間は実験条件に依存して1〜2msの範囲であった。電子熱伝導率は3つの異なる独立した方法で決定され、それらの結果は合理的に一致したが、ジャイロトロンパワーの1/4〜1/3のみがプラズマエネルギーの変化率として見出された。その他の検討項目としては、不純物含有量と輸送、セーバー挙動、MHD安定化、ECRH中の超熱電子集団およびペレット入射が挙げられる。
