The minimum dimension of an ITER like tokamak with a given Q is calculated for two values of the maximum magnetic field in the superconducting toroidal field coils. For ITERH-98P (y,2) scaling of the energy confinement time, it is shown that for a sufficiently large tokamak, the maximum Q is obtained for the operating point situated both at the maximum density and at the minimum margin with respect to the H-L transition.
