Microwave-based diagnostic techniques have major advantages in
high temperature/burning plasmas more robust that optical diagnostics:
– no in-vessel / first wall optical windows/mirrors needed

We investigate here the interaction of the mirror plasma scrape-off layer, characterized by drift-interchange turbulence with an exponential toroidal wavenumber spectrum, and the much more quiescent FRC core, characterized by very low ion-scale turbulence levels, and a flat or inverted toroidal wavenumber spectrum.
