• 論文の詳細を見る

• We have observed two kinds of magnetohydrodynamic (MHD) instabilities excited in a current-carrying cylindrical plasma that was produced by a magneto-plasma-dynamic (MPD) arcjet. The "net current" in the plasma excites the instability with the azimuthal mode number m = 1, which is deduced to be a kink mode from MHD theory. On the other hand, the m = 0 instability is excited by the "total current" flowing to the cathode, and this mode was found to be responsible for the modulation of electron temperature. They are converted respectively to m = 1 compressional Alfven wave and m = 0 global Alfven eigenmode, propagating along the axial magnetic field in the current-free region.
