摘要

描述
English: One-volt en:voltage standard developed by en:NIST (formerly en:National Bureau of Standards (NBS) until 1988) based on an array of 3020 superconducting en:Josephson junctions, operating at liquid-helium temperatures. Microwave energy fed into the finguide structure on the left generates a voltage across the 4 chains of junctions on the right.
日期 apparently 1985-1988
