چکیده
|
Formation of singular vortices in a magnetized plasma is presented. one is plasma hole, which is characterizedby fast azimuthal rotation and a density hole in its core region. it is found that the charge neutrality condition doesbreak down in the hole region over 1000 times the debye length. another example is an anti-e × b vortex, whichrotates in the opposite direction to the e × b drift. this result means that there exists a predominant force acting onions other than the electric field. the interaction between ions and neutral flow and the resultant momentum transferplay an essential role on generation of anti-e x b rotation.
