Abstract To assist the design effort of the TF (toroidal-field) coils for the CIT (Compact Ignition Tokamak), a set of programs was developed to calculate the transient spatial distribution of the current density, the temperature, and the forces in the TF-coil conductor region. The TF coils are of the Bitter (disk)-type design and therefore have negligible variation of current density in the toroidal direction. During the TF pulse, voltages which cause the field and current to diffuse in the minor radial direction are induced. This penetration, combined with the increase of resistance due to the temperature rise, determines the distribution of the current. After the current distribution has been determined, the inplane (TF-TF) and the out-of-plane TF-poloidal field (TF-PF) forces in the conductor are computed. The predicted currents and temperatures have been independently corroborated using the SPARK code modified for this type of problem.<<ETX>>
