| Research Abstract |
To understand the mechanism of particle acceleration and transport in solar flares, we develop a numerical model based on the drift-kinetic theory. Under a potential magnetic field configuration, we find that electrons are accelerated at the top of closed loops and along open field lines. With including the pitch-angle scattering, the peak height of loop-top electrons depends on their energy. This result can explain the origin of the "above-the-loop-top" hard X-ray sources. Under a more complicated field configuration, on the other hand, we find an impulsive electron flux along the closed field lines.
