Beam-driven chirping instability in DIII-D

W W Heidbrink1995年Plasma Physics and Controlled FusionIF 2.2出版社

During neutral-beam injection into the DIII-D tokamak, instabilities with frequencies that 'whistle' down a factor of two in a single 2 ms burst are observed between 50 and 200 kHz. The instabilities have toroidal mode numbers n=1-8 and cause the loss of beam ions from the plasma. In contrast to the usual Alfven modes, which are fluid modes of the background plasma, these instabilities seem to be beam modes that are nearly stationary in the plasma frame.

DIII-Dトカマクへの中性粒子ビーム入射中に、2 msの単一バースト中に周波数が2分の1に低下する(「ホイッスル」)不安定性が50~200 kHzで観測される。この不安定性はトロイダルモード数 n=1-8 を持ち、プラズマからのビームイオンの損失を引き起こす。通常のアルフヴェンモード(背景プラズマの流体モード)とは対照的に、これらの不安定性はプラズマの静止系でほぼ静止しているビームモードであると思われる。
