Nonideal, helical, vortical magnetohydrodynamic steady states

Y Z Agim, D Montgomery1991年Plasma Physics and Controlled FusionIF 2.2出版社

The helically-deformed profiles of driven, dissipative magnetohydrodynamic equilibria (MONTGOMERY et al., 1989, Phys. Rev. A 40, 1515) are constructed through second order in helical amplitude. The resultant plasma configurations are presented in terms of contour plots of magnetic flux function, pressure, current flux function and the mass flux function, along with the stability boundary at which they are expected to appear. For the Wisconsin Phaedrus-T Tokamak, plasma profiles with significant m=3, n=1 perturbation seem feasible; for these, the plasma pressure peaks off-axis. For the smaller aspect ratio case, the configuration with m=1, n=1 is thought to be relevant to the density perturbation observed in JET after a pellet injection.

螺旋変形した駆動・散逸磁気流体平衡(MONTGOMERYら、1989年、Phys. Rev. A 40, 1515)のプロファイルを、螺旋振幅の2次まで構成した。得られたプラズマのプロファイルは、磁束関数、圧力、電流束関数、質量束関数の等高線図として示され、それらが現れると予想される安定性境界とともに提示される。ウィスコンシン州のPhaedrus-Tトカマクでは、m=3、n=1の有意なプラズマプロファイルが実現可能と思われる。これらの場合、プラズマ圧力は軸外でピークに達する。より小さいアスペクト比の場合、m=1、n=1の配位は、ペレット注入後にJETで観測された密度摂動に関連すると考えられる。
