Forced radial oscillations of a fully ionized cylindrical plasma surrounded by a partially ionized plasma shell
Forced radial magnetoacoustic oscillations of a fully ionized cylindrical plasma surrounded by a partially ionized plasma shell are excited by means of an external source. The radial profiles of the macroscopic field quantities in the fully and partially ionized regions are obtained as functions of the degree of ionization, the temperature, and the position of the boundary between the two regions. The absorbed power is calculated. The nonresonant as well as the resonant cases are treated. It is shown that the main part of the power is absorbed in the outer shell unless a suitable resonance is used to enhance the macroscopic field quantities in the fully ionized plasma part and the dimensions of the outer shell are kept small.
