Abstract
This project is designed to deposit coatings of the Thallium based high temperature superconducting (HTS) compound, T1-2-2-2-3, onto substrates with complex geometries, appropriate for use as magnetic shields in DC cryogenic current comparators (CCC's). In this first phase, MSI will coat MgO substrates with the length, diameter, and internal passages appropriate to magnetic shields for CCC designs presently being considered by NIST. The establishment of a suitable metallic substrate and the development of the processing procedures for applying HTS coatings to complex, thin walled shapes, based upon that substrate, for potential fabrication of even more complex shield geometries, will also be completed. Later phases will be aimed at demonstrating the production of magnetic shields on an appropriate metallic substrate and incorporation of those shields into a demonstration CCC for commercialization as an electrical resistance standard.
