WitrynaImpurity ions of sufficiently high mass are deeply trapped by a centrifugal potential well in the outer plasma midplane, with a bounce period that is shorter than both the bounce period of magnetically trapped ions and the collision time. The collisional diffusivity in this regime is shown to be higher than that of a non-rotating plasma. Witryna26 maj 2024 · Apparently, the impurity ions play dual roles in the dynamics of GAM zonal flow: one is that the GAM damping rate increases through wave–particle interaction as the GAM frequency reduces and more bulk ions could resonate with the GAM; another is the reduced work done for the GAM zonal flow due to the reduction in tilting … Witryna4 mar 2024 · Abstract: Spectral intensities emitted from high- metal impurity ions of Fe 22+ at 132.91 Å, Mo 30+ at 115.999 Å, Mo 31+ at 127.868 Å, W 42+ at 129.41 Å, W … china star north ave elizabeth nj
