| Outline of Final Research Achievements |
Flow structure of rotating plasma in an inhomogeneous magnetic field was studied with the HYPER-II device. We developed a multi-cylindrical electrode to control the angular momentum of plasma. In order to understand the effect of plasma rotation on flow and electric field structures in the ion-unmagnetized plasma region. The electrode produces a radial electric field (typically 1 V/cm), and its direction and spatial profile are controlled by changing the bias pattern. It was confirmed that the azimuthal plasma rotation due to the ExB drift is produced in the magnetized region.
When the angular velocity increased, a reversal flow configuration was found. In addition, the characteristics of reversal flow structure observed in the magnetized region tends to change in the ion-unmagnetized region. This indicates that the effect of plasma rotation on the ion acceleration along the magnetic field line is important.
