Properties of linear and nonlinear ion acoustic (IA) waves, propagating obliquely to an ambient magnetic field in pair-ion plasma containing a fraction of Boltzmannian electrons, are investigated. The Zakharov–Kuznetsov equation is derived for IA wave in the nonlinear regime, which admits the solitary wave solution. It is found that nonlinear profile of the IA solitary wave is significantly affected by the obliqueness, magnetic field, and the electron concentration. It is determined that the obliqueness influence both the amplitude and width of the soliton, whereas the other parameters mainly affect the width of the soliton. The results presented in this paper can be useful for future experimental investigations of pair-ion fullerene plasma.

    NSTX-Upgrade will operate with toroidal magnetic fields (BT) up to 1 T, nearly twice the value used in the experiments on NSTX, and the available NBI power will be doubled. The doubling of BT while retaining the 30 MHz RF source frequency has moved the heating regime from the high harmonic fast...

    The effects of friction on the ion acoustic (IA) wave in fully and partially ionized plasmas are studied. In a quasineutral electron-ion plasma the friction between the two species cancels out exactly and the wave propagates without any damping. If the Poisson equation is used instead of the...
