Self-ordering of electromagnetic drift waves in a bounded plasma
Abstract
A packet of electromagnetic drift waves in a bounded plasma cylinder is shown to self-order into vortex structures moving in the azimuthal direction at a constant angular velocity. The structure represents a bound state of vortex satellites of the cyclon-anticyclon type. Their formation is energy-efficient due to the negative polarity of the wave component of the turbulence energy and is self-maintained due to dissipative processes. These structures may be observed in a laboratory plasma. They lead to increased convective particle and heat transfer and thus constitute structural elements of drift instability.
