Electron microbursts represent short electron precipitation having durations of less than ~1 sec at L=4-8. Measurements by Korean STSAT-1 (Science and Technology SATellite) have revealed two important unique microburst characteristics: (1) Electron microbursts are produced by fast loss cone filling process in which the interaction time for pitch angle scattering is less than 50 msec and (2) The e-folding energy of perpendicular component is larger than the parallel and the loss cone is not completely filled by electrons. To understand how wave-particle interactions could generate microbursts, we performed a test particle simulation and show how waves scatter electron pitch angles within the time scale required for microburst precipitation. Application of the rising frequency whistler mode waves to the different energy electrons moving in a dipole magnetic field shows that the chorus magnetic wave fields rather than electric fields are the main cause of microburst events implying microbursts could be produced by a quasi-adiabatic process. In addition, the simulation results show high energy electrons can resonate with chorus at high magnetic latitudes where the loss cone is larger, possibly explaining why precipitating microbursts have lower e-folding energies than the trapped electrons.
