Xm. Qiu et Xd. Peng, Optimization of electron density and temperature profiles in tokamak via safety factor profile, CHIN PHYS L, 18(8), 2001, pp. 1101-1102
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.
