Abstract :
Three 1 V binary Josephson arrays developed by the NIST, the PTB and the VTT and using respectively SNS (superconductor-normal-superconductor), SINIS (superconductor-insulator-normal-insulator-superconductor) and externally shunted SIS (superconductor-insulator-superconductor) junctions have been tested at BNM-LNE. Preliminary results of direct comparisons with conventional SIS arrays globally show a good agreement of less than 0.5 nV, at any nominal voltages between 41 mV and 1.3 V.
