The acceleration of energetic electrons associated with chorus observed by TC-2

Flux of high energetic electrons in the Earth's outer radiation belt varies dramatically during enhanced magnetic activities. Local electron acceleration to relativistic energies is prevalent during the storm recovery. However, it is not fully understood. Data of Low frequency waves and high energy electron fluxes from TC-2 were used to study electron flux and the relationship with whistler mode chorus during the Nov. 7(th)-11(th) storm in year 2004. Relativistic electrons accelerated from a few hundred KeV seed electrons were observed, and meanwhile the fluxes of the seed electrons have been observed gone down.
