Abstract

The principal objectives of the PITR are to demonstrate the attainment of thermonuclear ignition in D-T, and to develop optimal start-up methods for tokamak power reactors. The design approach is based on minimizing dependence on a central transformer core, which thereby results in a machine of small aspect ratio (A similar 2 to 2. 5) and small major radius (R//o similar 2. 8 m). Current induction is achieved by a combination of ″leaky OH″ coils, equilibrium-field flux swing, a small central solenoid, and compression. Impurity control is effected by a bundle divertor during the beam-heating phase, and by a cold plasma blanket during the burn. The vacuum vessel is constructed of thin-gauge, double-wall titanium alloy. Sixteen normal-copper TF coils of the compound constant-tension type enable low-stress operation at B//m//a//x equals 12. 5 T.
