AE-induced zonal flows

2024 Research Campaign, Thrust: Fast Ions, Turbulence and Alfven Waves Interaction

Purpose of Experiment

Zonal flows are theoretically predicted to reduce the amplitude of unstable Alfven eigenmodes. The goal of this experiment is to observe Alfven-eigenmode induced zonal flows.

Experimental Approach

Reproduce two conditions where Alfven-induced zonal flows have been observed in simulations and a third condition where they are likely to occur. Use BES and DBS to observe the zonal flows.
