Loss cone structure for ions in the TJ-II helical axis stellarator Part I: Properties without a radial electric field

J. Guasp, M. Liniers2000年被引用 18Nuclear FusionIF 3出版社

Losses and trapping regions in real and velocity space have been studied in the TJ-II flexible heliac for collisionless ions of low and intermediate energy (0.1-1 keV, roughly). The complexity of the magnetic field structure is described with emphasis on the ripple, Fourier mode composition, angular dependences and drift velocity behaviour. The resulting strong asymmetries of the loss distributions are discussed and explained. The influence of pitch and position is analysed by means of different complementary diagrams and a strong sensitivity to the angular position of trapping regions is shown. Electric field effects have not been included, this will be done in a companion article, with particular stress on the influence of resonances.

実空間および速度空間における損失と捕捉領域が、低・中間エネルギー(おおよそ0.1〜1 keV)の無衝突イオンについて、TJ-IIフレキシブルヘリアックにおいて研究された。磁場構造の複雑さは、リップル、フーリエモード構成、角度依存性、およびドリフト速度の挙動に重点を置いて記述される。損失分布の結果として生じる強い非対称性について議論し、説明する。ピッチおよび位置の影響は、異なる相補的ダイアグラムを通じて分析され、捕捉領域の角度位置に対する強い感度が示される。電場効果は含まれていないが、これは共鳴の影響に特に重点を置いて、姉妹論文で扱われる予定である。
