A New System of Toroidal Confinement of Plasmas

抄録

This paper exhibits a new toroidal system having the average minimum B-field without buried conductors. The existence of the closed nested surfaces is shown by the averaging method. A systematic analysis for the relations between rotational transform angle, well depth and mirror ratio along field lines is made by numerical computation. The configuration with the modest well depth and the appreciable rotational transform angle is found, although the requirement for deep well depth contradicts with that for large rotational transform.
