The article focuses on a numerical analysis of the projected use of the T-15MD tokamak machine after its physical launch for generating a configuration with negative triangularity of the plasma filament cross section (an inverted D shape) on the installed magnetic field coils. The study is of interest in connection with recent experiments on several tokamaks that have demonstrated a distinct improvement achieved with such operating regimes compared with standard plasma containment configurations.
