A set of transport equations using canonical ion and electron temperature profiles is proposed. Simulations of electron cyclotron resonance heating on T-10 and of the L-mode in TFTR, JET and ASDEX have been performed. From an analysis of the results of the calculations it is possible to construct universal expressions for heat fluxes without free parameters. On the basis of the developed model, several predictions are made for the International Thermonuclear Experimental Reactor (ITER).

The canonical profiles transport model is extended to describe various modes with improved confinement in tokamaks. A generalized profile consistency principle is proposed and a corresponding mathematical formalism is formulated. This formalism is used for the modelling of various regimes, such as H modes in DIII-D, JET and ASDEX, the hot ion mode and enhanced performance after pellet injection (PEP mode) in JET. This modelling, together with a known global scaling law, allowed the dependence of the internal model parameters on the plasma geometry and other physical variables to be established. This makes the model predictive. The approximate analytical criteria for the L to H and L to hot ion mode transitions are also obtained

The authors report the results of ion temperature measurements in the T-10 tokamak, with allowance for corrections due to the effect of kinetic transport of ions to the energy spectrum of atoms. On the basis of the experimental data they analyse the ion energy balance in the Ohmic heating and ECRH regimes over a broad range of plasma parameters.
