Outline of Final Research Achievements

We performed a numerical modeling of particles acceleration in solar flares. We performed high resolution 3D magnetohydrodynamic simulation of solar flares, where unsteady patchy reconnection and turbulent structure of a current sheet with small plasmoids are reproduced. The ejections of both small scale and large scale plasmoids affect particle acceleration, by enhancing electric field both in micro and global scales. We found test particles accelerated in a turbulent current sheet, and also in an erupting flux rope. We also theoretically showed that the power-law distribution of energy spectrum of particles can be naturally explained by the fractal of magnetic reconnection. Finally we compared our simulation results with solar radio observations.
