ジャーナル フリーA magnetic field having an average Minimum B configuration can Be produced by immersing the negative coils of the heliotron field in the plasma. Assuming the sheet current model, the general expression of this magnetic field is deduced. Some of the field : properties such as the effect of the position of the neutral lines are discussed.
In this Configuration, the neutral lines, on which the magnetic field intensity is zero, encircle the minor axis of the torus, while they encircle the major axis in the case of the toroidal multipole. The separatrix is farmed by the field lines which cross the neutral lines, and the bottom of th6.mane.tic well is on the separatrix. The equivalent potential, U=-_??_dl/B, increases monotonically from the separatrix towords the wall of the vacuum vessel, so that the plasma injection into the well may Be easily attained. Besides, the potential in the : region near the wall is higher than that on the magnetic axis.抄録全体を表示PDF形式でダウンロード (1475K) -

ジャーナル フリーThe plasma confinement by the Heliotron magnetic field with helical or poloidal inner conductors is proposed. This field forms a magnetic well of the potential, Ti =-∫dl/B, and the bottom of the potential well is in the region near the separatrix. When the plasma fills up the region inside maximum U surface, the plasma is stable for flute instability. The plasma inside separatrix is stable as far as the region just outside the separatrix is filled up by plasma. It is important that the plasma inside the separatrix is stable and it does not contact with the supporters of the inner conductors. The Plasaa outside the separatrix will be lost gradually due to the supporter loss. When the plasma density just outside the separatrix becomessufficiently low, the plasma inside the separatrix starts to leak out from the region inside the separatrix due to instability. Therefore, if we compensate the plasma loss due to the supporter by gun plasma injection or other means and keep the Plasma density just outside the separatrix constant, the plasma inside theseparatrix will be confined stably and theconfinement time will be extended considerably. The substitution of the old plasma by the newly injected plasma will take place only in the region outside, the separatrix. but not inside the separatrix.抄録全体を表示PDF形式でダウンロード (588K)
