UTSI/CFFF MHD PROGRAM COMPLETION AND RELATED ACTIVITY

Maintenance of the DOE CFFF facility was suspended, due to a stop work order issued in September 1998. Property accounting actions were continued on a minimum basis with university funding. No work was done on the environmental management and environmental restoration for the facility. Continued progress is reported on the five (5) high temperature superconductivity projects under Task 6. A cooperative group has been formed to facilitate the development of chemical processes for the manufacture of HTS superconductor wire. The group includes EURUS Technologies, Incorporated, Sandia National Laboratory, Clemson University, University of Houston and the National Magnet Laboratory. The ac loss project continues laboratory work in an effort to determine the optimum configuration for multiple conductor cables to minimize the ac loss. The cost/performance analysis concentrated on addressing comments on the draft Topical Report on the life cycle cost analysis of coated conductor manufacture by electron beam and PLD. Work on diagnostics for real time process control reported includes surface smoothness measurement by scatterometry, Raman scattering for real time determination of crystalline structure and oxygen content and atomic absorption measurements for control of stoichiometry in MOCVD deposition of YBCO
