A scaling law for high density and high current tokamaks is presented on thebasis of the nonlocal theory of electrostatic current-driven drift instability' inboth collisionless and collisional regimes with the assumption of quasilinearsaturation level. It is shown that the energy confinement time scales as rgocnq(a)/ 's/ T. (n, T. and q(a) are the averaged density, electron temperature and thesafety factor at the plasma edge.) in relatively lower density region and r.ccB/ Vn. (B is the toroidal magnetic field) in higher density region where a combined effectof the electron collisions and of a plasma current works. Trapped particle effectsare assumed to be negligible and no magnetic fluctuation is considered. A testexperiment of the scaling law on the J.[.I.P.T-II device where both tokamakoperation and the operation with superposition of helical fields are possible isproposed. ..
