Anisotropic distribution of alpha particles in a tokamak reactor
We carried out systematic study of neoclassical equilibrium distribution of α particles born from deuterium–tritium nuclear fusion in a tokamak reactor. The distribution in the phase space is visualized in various 2D planes. We studied a previously known but less investigated phenomenon—the co-curre...

| description | We carried out systematic study of neoclassical equilibrium distribution of α particles born from deuterium–tritium nuclear fusion in a tokamak reactor. The distribution in the phase space is visualized in various 2D planes. We studied a previously known but less investigated phenomenon—the co-current flow of α particles. We gave detailed explanation for this flow by examining the collisionless evolution of toroidal filament sources, using both the guiding-center drift model and full orbit model. We found that the flow appears because of the co-count asymmetry, which makes co-going α particles on average stay in weaker magnetic field region than that of the counter-going ones. |
