| Outline of Final Research Achievements |
We developed a Multi-moment advection scheme for Vlasov simulations of magnetized plasma. The scheme treats zeroth to second order piecewise moments of a physical profile as dependent variables to preserve its shape as much as possible. It enables us a long time calculation of linear advection and solid-body rotation problems with little numerical diffusion, which is a necessary ability for Vlasov simulations of magnetized plasma.
We applied the scheme to electromagnetic Vlasov simulations. In addition to linear problems, we succeeded in simulating nonlinear problems such as magnetic reconnection. Our code clearly described a complex structure of the plasma velocity distribution function around the reconnection region. These benchmark tests show that our scheme is a powerful technique for kinetic plasma simulations based on the Vlasov model.
