چکیده
The linear and the non-linear behaviors of ion temperature gradient (ITG) mode in a plasma with regularized κ-distributed electrons are investigated using fluid model. dispersion relation ITG obtained on basis local approximation shows that growth rate decreases increase spectral index κ exponential cut-off parameter α. It indicates presence superthermal electron leads to destabilization mode, especially low ( < 1.5) region. In addition, existence nature soliton structure driven by studied pseudopotential technology. amplitude increases α κ, whereas width varies inversely. present results will help understand low-frequency electrostatic wave nonlinear space experimental plasmas non-thermal electrons.

Large amplitude dust ion acoustic solitons: considering dust polarity and nonextensive electrons
The characteristics of arbitrary amplitude dust ion acoustic solitary waves (DIASWs) are studied in unmagnetized dusty plasmas whose constituents are cold uid ions, nonextensive electrons and stationary negative/positive dust particles. The pseudopotential approach has been used to investigate the structure of localized waves. It is found that, solitary waves exist in a definite interval for th...
متن کاملZonal flow generation in ion temperature gradient mode turbulence
In the present work the zonal flow ~ZF! growth rate in toroidal ion-temperature-gradient ~ITG! mode turbulence including the effects of elongation is studied analytically. The scaling of the ZF growth with plasma parameters is examined for typical tokamak parameter values. The physical model used for the toroidal ITG driven mode is based on the ion continuity and ion temperature equations where...
