Abstract :
The poloidal field and the vertical stability control coil systems for the Tokamak Physics Experiment (TPX) have time varying currents which breakdown and initiate the plasma current, provide the volt seconds necessary to ramp the plasma current to 2 MA, and maintain the plasma shape and position. The effects of the 3-D eddy currents induced in the cold structure of the machine on the Joule heating of the TF cell support structure, as well as on the quality of the field during the plasma breakdown and initiation phase are analysed in this paper
