| Popis: |
The saturated state of the current-driven ion-acoustic instability in a He positive-column plasma is studied using CO$sub 2$-laser scattering and heterodyne detection. It is found that small concentrations of hydrogen present in the positive-column plasma play a crucial role in saturating the instability. The measured angular extent and level of saturation of the turbulence are found to be consistent with ''resonance-broadening''-enhanced ion Landau damping by 1 to 4% H$sup +$ impurity ions. (AIP) |
