Abstract:
The nonlinear wave structures of large amplitude ion-acoustic waves are investigated in a plasma with an electron beam, by the pseudopotential method. The region of the existence of ion-acoustic waves is examined, showing that the condition of the existence sensitively depends on the parameters such as the electron beam temperature, beam density, the ion temperature and the electrostatic potential. It turns out that the region of the existence spreads as the beam temperature increases but the effect of the electron beam velocity is relatively small. New findings of large amplitude ion-acoustic waves in a plasma with an electron beam, are predicted.
