  journal={IEEE Transactions on Applied Superconductivity},
Effect of filament configuration and heat treatment of Bi2212/Ag round wire with low Ag ratio on the engineering critical current density (J<sub>e</sub>) was reported. We have fabricated 557, 85 7, and 121 7 wires with different Ag ratio and evaluated at various wire diameters. We have also changed the parameters of heat treatment. The effects of maximum process temperature (T<sub>max</sub>)and soaking time at T<sub>max</sub> and average filament diameter on the J<sub>e</sub> were also studied… CONTINUE READING
