The Seventh Intercomparison of Josephson Voltage Standards in North America



Yi-hua D. Tang, Clark Hamilton, David Deaver, Harold Parks, Barry Wood


The 7th interlaboratory comparison (ILC) of Josephson Voltage Standards (JVS) at 10 V, sponsored by the National Conference of Standard Laboratories International (NCSLI), took place from April to October 2005 with 15 participating labs. NIST?s traveling JVS system was used to make five comparisons with sub-pivot labs. This paper describes the protocol used for the JVS intercomparison, and the improvements achieved by the use of the transportable JVS.
