Development of Simplified RABiTS and IBAD Architectures for Coated Conductors

M. P. Paranthaman

Oak Ridge National Laboratory, Oak Ridge, TN 37831

High performance second generation superconducting wires can be fabricated in excess of 100 meter lengths based on four different templates such as IBAD-YSZ, IBAD-GSZ, IBAD-MgO, and RABiTS. In order to further reduce the manufacturing cost of these wires, it is necessary to simplify the buffer architectures. In this talk, we will address the current status of the simplified buffer architectures that have been developed for IBAD and RABiTS templates. In addition, we will also address the following important questions: (1) What are the important characteristics that must be exhibited by effective coated conductor substrates? (2) What are some of the possible issues that have prevented these simplified architectures from being incorporated into prototype coated conductors? and (3) To what extend must these architectures be developed before a wire manufacturer will consider implementing this technology into their prototype conductor?

Research sponsored by the US Department of Energy, Office of Electricity Delivery and Energy Reliability - Superconductivity Program, under contract DE-AC05-00OR22725 with UT-Battelle, LLC managing contractor for Oak Ridge National Laboratory.
