Abstract :
Results on high current density high volume fraction Nb7.5Ta MEIT conductor incorporating a Sn+Ti source with a Jc of more than of 3000 A/mm2 at 12 T are presented and compared to a MEIT conductor incorporating Ti in the Sn. The effect of two fins on the Deff and magnetization are discussed. Results on moderate volume fraction MEIT conductors with Nb1Zr filaments both with and without the addition of Oxygen are presented. The effect of oxygen on Jc, grain size and layer Jc are presented and discussed.
