Abstract:

Two epoxy-impregnated superconducting test coils, containing 0.635-centimeter electrical heaters imbedded in their windings, have been constructed to measure the minimum energy-to-quench as a function of operating current at various fixed levels of magnetic field strength. One test coil was wound with aluminum-stabilized NbTi superconducting wire and the other coil was wound with bronze matrix Nb3Sn superconducting wire. The results of the energy-to-quench measurements are presented for both these test coils, and these results are compared to the previous measurements made for copper-stabilized NbTi test coils.
