Abstract-Fermilab's cabling facility has been upgraded to a maximum capability of 42 strands. This facility is being used to study the effect of cabling on the performance of the various strands, and for the development and fabrication of cables in support of the ongoing magnet R&D programs. Rutherford cables of various geometries, packing factors, with and without a stainless steel core, were fabricated out of Cu alloys, NbTi, Nb 3 Al, and various Nb 3 Sn strands. The parameters of the upgraded cabling machine and results of cable R&D efforts at Fermilab are reported.

Fermilab is involved in the development of new generation high-field accelerator magnets using state-of-the-art Nb 3 Sn strands produced using different technologies. Two 1-m long models -mirror configuration and dipole magnet -were fabricated recently at Fermilab based on powder-in-tube (PIT) Nb 3 Sn strands with small effective filament size. This paper describes the parameters of superconducting strands and cable, the details of magnet design and fabrication procedure, and reports the results of PIT coil testing.

The design of the 12 GeV Torus required the construction of six superconducting coils with a unique geometry required for the experimental needs of Jefferson Labs Hall B. Each of these coils consists of 234 turns of copper stabilized superconducting cable conduction cooled by 4.6 K helium gas. The finished coils are each roughly 2 X 4 X 0.05 meters and supported in an aluminum coil case. Because of its geometry new tooling and manufacturing methods had to be developed for each stage of construction. The tooling was designed and developed while producing a practice coil at Fermi National Laboratory. This paper describes the tooling and manufacturing techniques required to produce the six production coils and two spare coils required by the project. Project status and future plans are also presented.

The CLAS12 Torus is a toroidal superconducting magnet, part of the detector for the 12 GeV accelerator upgrade at Jefferson Lab. The coils were wound/fabricated by Fermilab, with JLab responsible for all other parts of the project scope, including design, integration, cryostating the individual coils, installation, cryogenics, I&C, etc. The paper provides an overview of the CLAS12 Torus magnet features, and serves as a status report of its installation in the experimental hall. Completion and commissioning of the magnet is expected in 2016.
