Abstract: | Nonlinear interaction of a large amplitude ducted helicon (whistler wave) with slow plasma motion is considered. The low-frequency response accounts for a finite ion gyroradius effect to the usual MHD Alfvén waves. It is found that this coupling leads to a filamentation instability which grows at a rate faster than those reported earlier. |
