概要
- 論文の詳細を見る
Alfvén eigen modes were observed in the Large Helical Device for various magnetic field strengths and plasma densities. It was found that Alfvén eigen modes could be excited at much higher frequencies (0.5 ˜ 2.5 MHz) and higher magnetic fields (1.5 ˜ 2.83 T) than previously reported. A part of the estimated Alfvén velocities (2 ˜ 6 × 107 m/s) exceeded the thermal velocity of injected neutral beams (˜ 4.1 × 106 m/s).
