This paper presents two contributions to the development of the in situ process for production of high field Nb/sub 3/Sn-Cu superconducting wire. First, in the utilization of multidie drawing equipment for reduction of Cu-Nb alloy castings to wire size, even though the alloy is quite ductile, it is desirable to utilize some intermediate anneals to insure zero breakage. It is shown here that these anneals can be controlled to improve the J/sub c/ properties of the wire. Second, a technique is presented for the production of a cryostabilized in situ wire which is compatible with large scale production methods. The technique utilizes a combination of rolling and extrusion to produce wire with a stabilizing Cu core.
