Abstract — The RABiTS^TM/MOD-YBCO 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 current production-scale equipment is designed to process strips with a width up to 10 cm and length up 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 startup issues were experienced during the commissioning of the production line. This paper describes some of the successes in addressing these issues, as well as ongoing efforts to improve processing yield.
