The U.S. INTOR team invested considerable effort in superconducting poloidal field (PF) coil studies, relating them to ongoing development programs for pulsed superconductors. A 50 kA Los Alamos National Laboratory (LANL)-type conductor was chosen as reference conductor, with a 100 kA conductor with surrounding channel support chosen as backup. Four distinctive features of the U.S. INTOR design are: (1) a PF coil system asymmetric about the midplane, resulting from the single-null divertor and the off-center plasma, (2) a central solenoid with separate segments for ohmic heating (OH) and equilibrium field (EF), (3) ring coils with combined OH and EF function, each with its own time history, and (4) ring coils mounted outside, but very near, the toroidal field (TF) coils. The force analysis must be carried out for all times of the cycle, and must include the fringe field from the TF coils. The forces on the ring coils can be reduced greatly, at little added expense, by moving the PF ring coils further from the TF coils.
