Space Chamber Simulation of Altitude Variation on Plasma Wave Signatures
Abstract
The effects of increasing ion-neutral collisions on velocity-shear-driven ion cyclotron waves have been studied in simulated ionospheric conditions in the Naval Research Laboratory's Space Physics Simulation Chamber. The experiments show that shear-driven ion cyclotron waves can exist for ion-neutral collision frequencies of the order of the ion gyrofrequency. For higher collision frequencies where the ions become unmagnetized, a transition to a higher frequency mode is observed.
