Abstract The turbulent particle and thermal transport scaling laws are derived by means of Lagrangian invariant of trapped electron dynamics in tokamaks, which are in good agreement with experimental results. On the basis of the two scaling laws, it is proposed that the optimization of electron density and temperature profiles can be achieved by designing a desirable safety factor profile.
