| Research Abstract |
The potential and density structures associated with typhoon-like vortices observed at HYPER-I in NIFS have been self-consistently determined and shown to reproduce the experimental data. The potential has been obtained by solving a nonlinear equation involving the anomalous ExB drift and polarization drift for ions. The density structure is shown to be determined by the balance between the centrifugal force due to the anomalous ExB drift and the pressure.
