The MOD-YBCO/RABiTS route has been identified as a low-cost manufacturing process for high performance 2G wire. AMSC has used this approach to design a full-scale production line based on a "wide-strip" manufacturing process. The "wide-strip" process is designed to be inherently low-cost and has the flexibility to produce wire with varying dimensions and properties which can be tailored for specific applications. The current production scale equipment is designed to process strips with a width to 10 cm and length to 1 km; however, the initial operation of the equipment uses a 4-cm wide strip. As with any new manufacturing technology, a number of start-up issues were experienced during the commissioning of the production line. This presentation will describe some of the successes in addressing these issues, as well as ongoing efforts to improve processing yield. We will also summarize the performance of the 2G wire currently being produced and describe further performance improvements under development.
