Poloidal field system for the Tokamak Physics Experiment

The Tokamak Physics Experiment (TPX) at Princeton will be the first tokamak with an all superconducting poloidal field (PF) magnet system. The conductors are all cable-in-conduit (CICC) superconductors with a single conduit, similar to those in the International Thermonuclear Experimental Reactor (ITER). 10 of the PF coils use Nb/sub 3/Sn superconductor while 4 of them use NbTi. High noise initiation and disruptions demand the use of an advanced quench detection system. >
