The remarkable property of tokamak plasma is to maintain the shape of some parameters profiles (e.g. electron pressure …) under different external influences. This effect is considered as manifestation of plasma self-organization and corresponding normalized profiles are called stiff. The quantitative measure of the profiles stiffness appeared as a factor standing in front of the difference between temperature (or pressure) normalized gradient and the critical gradient in the expression for heat or particle fluxes in the Canonical Profiles Transport Model (CPTM).
The report presents the CPTM simulation results using ASTRA code for L-mode plasmas of circular limiter tokamak T-10 and D-shaped diverted plasmas of COMPASS. On top of that Ohmic and NBI heated H-mode in COMPASS was modeled.
The runs demonstrated density profiles and electron temperature pedestal in agreement with measurements. The results of L-mode simulation in COMPASS were compared with those obtained for T-10.
