Plasma flow velocity and its shear perpendicular to magnetic-field lines are generated by using the tungsten hot plate concentrically three segmented, which can form the radially-different plasma potential, or radial electric field even in a fully-ionized collisionless plasma. A drift-like instability which exists in the peripheral region, where the density gradient is relatively large, is observed to be suppressed by the perpendicular flow velocity shear in the central region.
