Title: Development of Long Length High Ic Thick YBCO Films Through MOD Process with Pinning Center Enhancement
Agency / Branch: DOD / OSD
Contract: FA8650-05-C-2627
Award Amount: $374,993.00


YBCO film through MOD approach is one of the most cost effective methods for long length CC fabrications. Although, this process has shown success on films below 1 micron, thicker films with the performance goal of 500-1000 A/cm have not been demonstrated even on small samples. Hence, long length thicker films of 1-3 micron through MOD approach with pinning center enhancement are yet to be fully developed to attain higher Ic and Je. High-density nanoscale pinning centers is the only way to keep Jc from dramatic degradation for thick films. In Phase I the feasibility of Ic>286A/cm and Jc>2.4 MA/cm2 for 1.2 micron YBCO films has been demonstrated. In Phase II, we propose to further increase the Ic limit and scale-up thicker film fabrication process. The major tasks will include: (1) optimization of MOD process steps on short lengths of RABiTS, IBAD and ISD substrates with appropriate buffers for thicker YBCO films (>2 micron) with high density nano pinning centers, and (2) scale-up of the optimized process to longer (>1 meter) tapes. UES has teamed up with Oxford Instruments for RABiTS and Los Alamos National Laboratory for IBAD substrates for the Phase II research.
