Instability of Electron Bernstein Mode in Presence of Drift Wave Turbulence Associated with Density and Temperature Gradients

The instability of electron Bernstein mode has been investigated in presence of drifts due to density and temperature gradient. Nonlinear resonant interaction of drift mode is considered for the investigation of the instability. We have considered a uniform force field $$\mathbf{F}$$ which is the cause of $$\mathbf{F}\times \mathbf{B}$$ drift due to temperature perpendicular to the magnetic field $$\mathbf{B}$$ in the system. Using Vlasov-Poissons system of equations and Maxwellian type distribution function of particles that involve the effect of $$\mathbf{F}$$ associated with density and temperature gradient. We have derived a nonlinear dispersion relation for electron Bernstein mode and then estimated its growth rate. We have analyzed various aspects of the growth rate of electron Bernstein mode associated with the variation of the gradients of the density and temperature by using experimental data in tokamak plasmas.
