Abstract:

Electrostatic ion-cyclotron waves are inspected with multi-ion plasma (H+, He+ and O+) using particle aspect analysis. The plasma is deliberated to contain of resonant and non-resonant particles. The resonant particles contribute in energy conversationalthough the non-resonant particles provision the oscillatory motion of the wave. The wave is supposed to propagate explicitly to the static magnetic field. Dispersion relation, growth rate, parallel and perpendicular resonant energy have been scrutinized for electrostatic ion-cyclotron waves with multi-component plasma. The influence of kappa distribution function with fluctuating plasma density is to enrich the growth rate of EIC waves with multi- component plasma (H+, He+ and O+). The kappa distribution acts as source of free energy. The fallouts are inferred for the space plasma parameters applicable to the cusp region nearby the earth’s magnetosphere. The schoolwork may clarify the EIC waves detected in cusp region and play a most important role of particle density variation in particular region.
