Distortion of the cross section of a tokamak has been suggested as a means of improving Ohmic heating and raising ..beta... We have investigated the effects of such distortion on the collisionless, electrostatic trapped-particle mode and find that under certain conditions a maximum-J configuration can be approached. Results will be presented for finite elliptic and triangular distortions, indicating significant stabilization. 6 refs., 4 figs.
