;
The presence of convective cells in a purely poloidal field Levitated Octupole has been associated with diffusion that scales as D/sub v/ (T* proportional to T/n) /sup 1/2/, independent of B, where T* is an effective temperature, T* proportional to T. The electric field spectrum of the convective cells can be used to estimate the magnitude of T* and D/sub v/. The results are in reasonable agreement with previous measurements of cross-field transport, and agree qualitatively with theoretical models of vortex diffusion.
