The transition between the anomalous diffusion previously reported in pulsed multipoles and classical diffusion has been observed at low poloidal magnetic fields,B≲100 G. The helium plasma parameters werene=1010–1011cm−3,Ti∼Te∼0.2 eV. The anomalous diffusion seen at higher magnetic fields scaled like vortex diffusion, but the transition point corresponds to a nonthermal vortex spectrum with effective temperature,T*∼106eV. Transition from anomalous to classical regime is observed on a classical viscous damping time scale.
