Estimation of Filamentary Transport Parameters at the Edge of Tokamak MEPhIST-0
The parameters of the convective filamentary transport in the edge region of the small spherical tokamak MEPhIST-0 are estimated. To describe dynamics of the installation scrape-off-layer plasma, an electromagnetic two-fluid MHD model was employed. The operational parameters of the tokamak and their impact on the characteristics of turbulent plasma transport are discussed. Using the BOUT++ code, dynamics of isolated filaments were simulated under conditions corresponding to the edge region of the tokamak in various discharge scenarios. It is shown that, despite the compactness of the machine, it may be possible to create and study both electrostatic and electromagnetic regimes of anomalous edge plasma transport in the installation.
