Unstable Ion Waves in a Bounded Ion-Beam Plasma System

- 論文の詳細を見る
A dispersion relation is derived for an ion-beam plasma system in a conductingcylinder. The dispersion relation obtained is examined numerically in order toclarify the boundary effect on the propagation of the longitudinal waves. Manyeigen modes are found. These modes are found to be unstable even if they areexpected to be stable in an infinite system. This instability is caused by an interac-lion of the ton beam with the wave which is influenced to propagate obliquelyby a finite radius of the cylinder. The unstable frequency range shifts from higherto lower mode with increasing a length of the cylinder. The growth rate of theunstable waves is large for large value of b.,./a, where a and b-,. are the radiusof the cylinder and the nth zero of the mth order Bessel function of the first kindrespectively.
