Effect of Magnetic Shear on the Electrostatic Ion Cyclotron Waves in Magnetospheric Plasmas.

Abstract

The importance of the effect of the magnetic shear on the current driven ion-cyclotron instability for the space plasmas is illustrated. A non-local treatment is used. Even for infinitesimal magnetic shear a large reduction in the growth rate is found along with a noteworthly reduction in the band of the unstable perpendicular wavelengths. The latter effect leads to an enhanced coherence as has been previously observed in the S3-3 data for electrostatic non-cyclotron waves. (Author)
