The Tokamak Physics Experiment (TPX) at Princeton will be the first to
kamak with an all superconducting poloidal field (PF) magnet system. T
he conductors are all cable-in-conduit (CICC) superconductors with a s
ingle conduit, similar to those in the International Thermonuclear Exp
erimental Reactor (ITER). 10 of the PE coils use Nb3Sn superconductor
while 4 of them use NbTi. High noise initiation and disruptions demand
the use of an advanced quench detection system.
