Observation of TAE activity in JET

S Ali-Arshad, D J Campbell1995年Plasma Physics and Controlled FusionIF 2.2出版社

High-frequency magnetic activity with characteristics expected of toroidicity-induced Alfven eigenmodes (TAEs) has been observed in JET discharges heated by neutral beam injection and ion cyclotron resonance heating. The mode frequency is found to scale in the expected way with the magnetic field and plasma density and the frequency spectra show the characteristic multi-mode TAE structures seen in other devices. A correlation between fast-particle loss levels and the mode amplitude is also suggested by the data.

JET放電において、中性粒子ビーム入射およびイオンサイクロトロン共鳴加熱によって加熱された際に、トロイダル性誘起アルフヴェン固有モード(TAE)に期待される特性を有する高周波磁気活動が観測された。モード周波数は、磁場およびプラズマ密度に対して期待される方法でスケーリングすることが見出され、周波数スペクトルは、他の装置で観測される特徴的な多モードTAE構造を示す。また、データは、高速粒子損失レベルとモード振幅との間の相関を示唆している。
