Abstract:

Nonlinear wave structures of arbitrary amplitude ion-acoustic waves in a relativistic electron-beam plasma system are studied using the pseudopotential method. The region of existence of arbitrary amplitude ion-acoustic waves is examined, and it is shown that the condition for their existence depends sensitively on parameters such as the relativistic effect of the electron-beam, the ion temperature, the electrostatic potential and the electron-beam density. It turns out that the region of existence spreads as the relativistic effect increases and the ion temperature decreases. New properties of large amplitude ion-acoustic waves in a plasma with a relativistic electron-beam are predicted.
