説明

H-mode has little controllability from the point of view of a steady state operation. By applying a high-m ergodic magnetic field, the suppression in density and radiation increase is observed with Hα bursts. And a steady state H-mode can be realized in JFT-2M. The total stored energy of the steady state H-mode shows some loss compared with that of the burst free H-mode. But it is only less than about 10% due to the suppression of density increase. The profiles of the core plasma density and temperature are almost the same with and without the ergodic field. The controlled region of the steady state H-mode can be seen as a belt above L/H threshold in neutral beam power versus ergodic field graph. That region increases with increasing the ergodic field. This demonstrates an active controllability of the H-mode.
