Plasma shield dynamics and target erosion in disruption simulation experiments

Dynamics of carbon plasma shields and graphite target erosion experimentally studied at the recently upgraded plasma gun facility MK-200 UG at TRINITI Troitsk are compared with numerical results from FOREV-2 which allows a 2-D modeling of hot plasma target interaction. It is shown that turbulent processes are absent in the experimental plasma shields. Anomalous lateral losses of plasma mass are not occurring and plasma shield dynamics can be described by the multidimensional radiation magnetohydrodynamics (R-MHD) equations together with a consistent solution of the multidimensional magnetic field equations with classical magnetic field diffusion coefficient.
