Abstract
A stability analysis is made for the n=1 external kink mode (n: toroidal mode number) to the predicted ITER L-mode profiles. The beta limit (g{sub T}) for this kink mode is sufficiently higher than the design value of g{sub T}=2.0-2.4 for the L-mode profiles in case of the assumed current profile even with a finite but small edge current. However, in case of q{sub 0} less than unity (q{sub 0}: safety factor on the magnetic axis) the beta limit for the kink mode is significantly reduced: g{sub T} is 1.0 for q{sub 0}=0.8 without a conducting wall. A conducting wall located near the mid-plane has a stronger stabilizing effect than a wall located near the null point. (author).
