Abstract
NIST is developing a cryogenic current comparator (CCC) to operate at 77K, using high-temperature superconductor (HTS) ceramic shielding mat erial and an HTS-based superconducting quantum interference device (SQ UID) detector. The shielding properties of at least two polycrystallin e oxide HTS materials appear sufficient for use in a high-accuracy CCC . A measurement of current-linkage error, a figure of merit for CCC de vices, is made for one type of HTS CCC. The design of a second HTS CCC which uses improved magnetic shielding is described.
