Macrotor physics and technology results

R.J. Taylor1985年被引用 3Nuclear FusionIF 3出版社

The fusion research result in Macrotor has been focused on the basic issues of impurity generation (O, C), the role of the radial electric field in particle and energy transport, magnetic turbulence, particle pumping with a limiter, and the development of a large-area ICRF coupler for phased arrays for current drive and plasma heating. The total impurity line radiation has been reduced below the value contributed by the hydrogen edge radiation in ohmically heated plasmas. In RF-heated discharges, edge electron heating and the corresponding influx of impurities have been reduced by k-parallel shaping using large-area phased ICRF couplers. The Faraday shields have been used as limiters, and are used to remove the plasma heat. Current drive due to the lower hybrid fast wave has been observed with these couplers.

Macrotorにおける核融合研究の成果は、不純物生成(O、C)の基本的な問題、粒子およびエネルギー輸送における径方向電場の役割、磁気乱流、リミッターによる粒子排気、ならびに電流駆動およびプラズマ加熱のための位相配列を用いた大面積ICRF結合器の開発に焦点を当ててきた。オーミック加熱プラズマにおいて、全不純物線放射は水素端部放射によってもたらされる値以下に低減された。RF加熱放電においては、k平行整形を用いた大面積位相配列ICRF結合器により、端部電子加熱およびそれに伴う不純物の流入が低減された。ファラデーシールドはリミッターとして使用され、プラズマ熱の除去に用いられている。これらの結合器を用いて、低ハイブリッド高速波による電流駆動が観測された。
