SELF-CONSISTENT MODEL OF CLOCK EVENT IN OUTER JOVIAN ELECTRON-RADIATION BELTS

The work considers nonlinear nonstationary processes in the outer Jupi ter electron radiation belts, which are alternating stages of accumula tion of particles and their precipitation in the ionosphere during a w histler radiation pulse. The cyclotron instability dynamics of the pla sma magnetospheric maser are described by the relativistic system of q uasilinear equations. This system takes into account the diffusion of: particles in adiabatic invariant space, synchrotron losses and electr omagnetic radiation evolution. Analysis shows the importance of the ef fect of global resonance i.e. the eigenfrequencies of oscillations of the belt parameters are practically independent of the magnetic shell and coincide with the planet's angular rotation velocity. Consideratio ns show that it is the 10 dynamics of outer Jovian electron radiation provide the coefficient of particle radiation which is necessary for g lobal resonance. In the outer Jovian radiation belts work like a pump accumulating energetic electrons from the periphery of the magnetosphe re. Copyright (C) 1996 Elsevier Science Ltd
