    Abstract
  • The local acceleration mechanism is one of the crucial factors for the high energy electron flux enhancement events in the outer radiation belt. There are two substantial preconditions for this acceleration mechanism. The first and the most important one is the presence of enough low energy electron (on the order of tens to hundreds of keV), so-called seed electron; the other is the enhancement of plasma waves including whistler chorus waves which can contribute to the electron acceleration by wave-particle interaction. Geomagnetic field data observed by Memambetsu (L=1.57) observatory are used to extract Pi1 pulsation during 2004-2006. The linear correlation between Pi1 pulsation duration and seed electron flux (LANL 50～225keV) is greater than 0.7, which indicates that the Pi1 pulsation duration is a good indicator of seed electron flux. After the investigation of three magnetic storms events in 2005, the evidence had been found for acceleration of seed electrons to high energies by whistler chorus waves and the positive correlation between the chorus waves' spectral density and high energy electron flux.
