Self-consistent model of clock event in outer Jovian electron radiation belts

The work considers nonlinear nonstationary processes in the outer Jupiter electron radiation belts, which are alternating stages of accumulation of particles and their precipitation in the ionosphere during a whistler radiation pulse. The cyclotron instability dynamics of the plasma magnetospheric maser are described by the relativistic system of quasilinear equations. This system takes into account the diffusion of particles in adiabatic invariant space, synchrotron losses and electromagnetic radiation evolution. Analysis shows the importance of the effect of global resonance, i.e. the eigenfrequencies of oscillations of the radiation belt parameters are practically independent of the magnetic shell and coincide with the planetʹs angular rotation velocity. Considerations show that it is the 10 h dynamics of outer Jovian electron radiation belts that provide the coefficient of particle radial diffusion, which is necessary for global resonance. In this sense, the outer Jovian radiation belts work like a pump accumulating energetic electrons from the periphery of the magnetosphere.
