2 - 12 Minute Quasi-Periodic Variations of 50 - 1000 keV Trapped Electron Fluxes Detected in the Afternoon Magnetosphere. 2. Theory of Adiabatic Modulations,
Abstract
A simple adiabatic theory of particle modulations is derived. Assuming that the perturbed magnetic field is time dependent but homogenous in space along the dipole direction, an expression for the change of particle fluxes in the equatorial plane is derived in terms of measurable quantities. We show here that the derived expression agrees well with observed characteristics of trapped electron fluxes measured by the University of Minnesota electron spectrometer on the ATS-1. In particular, quasi-periodic modulations of paper 1 are satisfactorily explained. (Author)
