Abstract :
We are using a quantum DC voltage generated on an array of high-temperature superconductor (HTS) junctions in the developed voltage calibrator with an output voltage up to 10 V. The described concept and the demonstrated parameters of the main parts of the instrument show that the measurement uncertainty of the output voltage will be a few parts in 10/sup 8/.
