波驱动刚体旋转环约束的效率

Efficiency of Wave-Driven Rigid Body Rotation Toroidal Confinement

J. -M. Rax, R. Gueroult, N. J. Fisch

摘要:

通过波驱动的极向旋转的环形磁场中的垂直漂移的补偿相比,通过波驱动的环形电流生成的补偿,以支持经典的磁旋转变换。与径向电场的维持相关的优点和缺点进行比较与极向磁场的维持相关的能量含量和功耗方面。径向电场的能量含量被发现是小于一个极向磁场的一组类似的轨道的能量含量。波驱动径向电场产生效率类似地示出,至少在大纵横比的极限中,大于波驱动环形电流产生的效率。

英文摘要:

The compensation of vertical drifts in toroidal magnetic fields through a wave-driven poloidal rotation is compared to compensation through the wave driven toroidal current generation to support the classical magnetic rotational transform. The advantages and drawbacks associated with the sustainment of a radial electric field are compared with those associated with the sustainment of a poloidal magnetic field both in terms of energy content and power dissipation. The energy content of a radial electric field is found to be smaller than the energy content of a poloidal magnetic field for a similar set of orbits. The wave driven radial electric field generation efficiency is similarly shown, at least in the limit of large aspect ratio, to be larger than the efficiency of wave-driven toroidal current generation.
