| Outline of Final Research Achievements |
It is known that high energy particles are produced in various astrophysical plasmas, for example solar flares and supernova remnants. The particles are believed to be accelerated by large-amplitude magnetosonic shock waves. However, the detailed mechanisms have not been clarified. Using electromagnetic particle simulations, we have clarified effects of electromagnetic fluctuations excited by trapped electrons on ion acceleration and positron acceleration. We have also studied nonlinear evolution of lower-hybrid wave instabilities driven by energetic particles. This result can contribute to both space plasma physics and fusion plasma physics.
