On the scaling of avaloids and turbulence with the average density approaching the density limit

This article is dedicated to the characterization of turbulent transport in the scrape-off layer of the Mega Ampere Spherical Tokamak [A. Sykes and et al. , Phys. Plasmas 8 , 2101 (2001)] as a function of the average density n L . The aim is to answer a renewed interest in this subject since the bursty character of turbulence in the scrape-off layer was shown to be caused by large-scale events with high radial velocity reaching about 1/10th of the sound speed called avaloids [G. Antar and et al. , Phys. Rev. Lett 87 , 065001 (2001)]. With increasing density, turbulence and transport increase nonlinearly at the midplane while remaining almost unchanged in the target region.
