Abstract :
The superconducting magnets in fusion reactors are subjected to heating from the pulsed operation of the poloidal field (PF) magnets, nuclear, eddy-current, and resistive heating. The thermo-hydraulic response of the helium forced-flow cooled conductors to the various heat sources is critical to magnet design and performance. Recently developed computer codes allow accurate modeling of conductor response and have been used as an aid to design of the toroidal field (TF) magnets for the Tokamak Physics Experiment (TPX). We present results of design studies that determine the trade-off between double- and single-pancake helium-flow configurations
