The U.S. Department of Commerce, National Institute of Standards & Technology (NIST), Electromagnetics Division proposes to negotiate on a sole source basis contract under the authority of 41 U.S.C. 253(c)(1) with the University of Colorado to perform electromechanical measurements of the effect of strain and stress on the critical current of low and high temperature superconductors. The goal is to determine the strain sensitivity of the high-field niobium-tin superconductors for the Department of Energy (DOE) fusion magnet program, and the electromechanical performance of Y-Ba-Cu-O coated conductors and Bi-2223 composites in conditions that simulate applications such as power transmission lines for the DOE program. The measurements are to be performed using specially designed NIST cryostats. The staff at the University of Colorado has a combination of skills and past experience in cryogenic-system design, handling of cryogenic fluids, operation of both high and low current sources, and extensive experience in axial-strain, transverse-compressive stress, and fatigue cycling experiments and measurement equipments. The staff also has a thorough knowledge of conduction properties and flux-pinning force mechanisms of superconductors to enable staff the essential analysis/interpretation needed to complete the tasks of this job. Specific work tasks will include measuring the effects of axial strain, transverse-compressive stress, and fatigue cycles on the critical-current of brittle superconducting materials including Nb3Sn, Y-Ba-Cu-O, and Bi-2223 composites. Full analysis of the data will be performed and strain models established.The contract period is August 1, 2005 through March 31, 2006. This procurement is being conducted per FAR Part 13, Simplified Acquisition Procedures (NTE $100K). This synopsis is issued for information only. No competitive solicitation is planned.
