Observation of beam-induced toroidal plasma currents and neoclassical current under neutral beam injection heating in Heliotron E

S Besshou, O Motojima, M Sato, T Obiki, A Iiyoshi, K Uo1984年Plasma Physics and Controlled FusionIF 2.2出版社

The authors report the observation of beam-induced toroidal plasma currents (<or=2 kA) excited by the neutral beams of 1 MW in Heliotron E. The induced plasma current is measured as a function of neutral beam power in both co-injection and counter-injection. The observed plasma currents are explained by the compound phenomena of the beam-induced (Ohkawa) current plus the neoclassical ('bootstrap') current.

著者らは、ヘリオトロンEにおいて、1 MWの中性ビームによって励起されたトロイダルプラズマ電流(2 kA以下)の観測を報告する。誘起されたプラズマ電流は、中性ビームパワーの関数として、コインジェクションおよびカウンターインジェクションの両方で測定された。観測されたプラズマ電流は、ビーム誘起(大川)電流と新古典(ブートストラップ)電流の複合現象によって説明される。
