This report covers progress by Team One of the DOE/OFE/D and T 12 Tesla Coil Development Program during the third quarter fiscal period of 1980. The basic mission of this effort is to demonstrate the feasibility of, and to establish an engineering data base for employment of bath cooled NbTi alloy to generate a peak field of 12 tesla in a tokamak reactor. General Atomic Company is the leader of Team One, with the Magnetic Corporation of America as industrial subcontractor. Phase I, development of a NbTi alloy, compositionally and process optimized for 12 tesla operation at temperatures below 4 K, was completed during FY 1979. Phase II, conceptual design of an ETF reactor compatible TF-coil system, employing the NbTi alloy selected by Phase I and an appropriate bath cooling regime, was completed during this reporting period. Progress was also made during this period on Phase III of this effort: Design construction and testing of a solenoid coil utilizing the selected reactor prototypical conductor and bath conditions. During this reporting period, two Phase IV tests were made at the General Atomic High Field Test Facility. Recovery tests were performed upon cabled conductor samples at 3 K and under superfluid (He II) conditions. Results therefrom will be reported in the Fourth Quarter Progress Report of this effort.
