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