ジャーナル フリーIn the toroidal coodinates, a equilibrium analysis is presented for a toroidally symmetrical, sharp boundary plasma. The plasma β and aspect ratio, Rp/rp, are assumed arbitrarily. In the equilibrium, the maximum plasma βp is evaluated as Max βp=1/4 (Rp/rp+rp/Rp) +1/2. When corrents flow on te plasmasurface and external conductors, a equilibrium magnetic iiela and the currents is analitically solved. In the case in which there exist the external conductors infinitely far from the plasma, a stagnation point and separatrix can be found near the plasma surface. Furthermore, the magnetic surfaces similar to the external conductors form can be found outside such the separatrix. The current density flowing on coils placed outside magnetic surfaces is much higer than that on inside them. The stagnation points exist inside and outside the coiles, or on the ones.抄録全体を表示PDF形式でダウンロード (973K) -

ジャーナル フリーA possibility of ion-heating by a coherent ion-acoustic wave is studied. Ions are accelerated periodically by the electrostatic potential of the ion-acoustic wave and their oscillation energy is converted into the thermal energy of ions through the collision with the neutral atoms in plasma. The Monte Carlo method applies to obtaining the heating-rate as the function of the quantities-the amplitude of electrostatic potential, the collision frequency and the mean-life of ions. The results agree with the experiment by Kawai et al., in which the ion-acoustic turbulence is excited due to the current-driven instability and is accompanied by the coherent wave with large wavelength. It is shown that the heating-rate is proportional to the amplitude of coherent wave.抄録全体を表示PDF形式でダウンロード (1048K)
