Abstract
Fermilab is developing high field superconducting dipole magnets based on N b3Sn for a post-LHC very large hadron collider (VLHC). The first prototype is a 1 meter long two-layer shell-type (cos-theta) coil with a nominal fiel d of 11T, A keystoned Rutherford-type cable made of 28 Nb3Sn strands of 1mm in diameter is used, The development of high J(c) multifilamentary Nb3Sn s trands with low magnetization is an important step of this program, To achi eve this goal, strand R&D is actively pursued by Fermilab and IGC using the internal tin process. Conductor designs, heat treatment studies, and resul ts of measurements, including I-c, n-value, RRR, magnetization, and chemica l analyses, are presented.
