Abstract

NIST is developing a cryogenic current comparator (CCC) to operate at 77 K, using high-temperature superconductor (HTS) ceramic shields and a HTS-based superconducting quantum interference device (SQUID) detector. HTS shielding at low magnetic field levels is probably sufficient for high accuracy measurements. Unshielded sections of the ratio windings may produce a significant error.<>
高温超导体低温电流比较器
NIST正在开发一种低温电流比较器(CCC),可以在77 K下工作,使用高温超导体(HTS)陶瓷屏蔽和基于高温超导的超导量子干涉装置(SQUID)探测器。在低磁场水平下的高温超导屏蔽可能足以进行高精度测量。比例绕组的非屏蔽部分可能会产生明显的误差。
