Ion Drift Wave Instability

Ion Drift Wave Instability

In hydromagnetically unstable, shearless plasmas the flute mode, k ‖  = 0 ;, is stabilized for sufficiently large k ⊥ by finite Larmor radius effects. It has been widely assumed that this mode is the worst. It is shown that this is not generally correct. In particular, those modes which are finite L...

Zusammenfassung:In hydromagnetically unstable, shearless plasmas the flute mode, k ‖  = 0 ;, is stabilized for sufficiently large k ⊥ by finite Larmor radius effects. It has been widely assumed that this mode is the worst. It is shown that this is not generally correct. In particular, those modes which are finite Larmor radius stabilized for k ‖  = 0 are unstable for 0
