Summary

In the first year of the iMERA joint research project “Binary Josephson Arrays Power Standard”, important foundations have been laid towards linking power standards to a quantum-based system. The amplitude of the Josephson arrays suitable for AC applications has been increased to the 10 V level and two alternative methods for the application of Josephson standards to power calibration have been developed and preliminary tests carried out. In addition, the switching transients between quantized voltage steps have been investigated at the 10 ns level and the calculation of the uncertainty in synthesized waveforms due to these transients has been improved.
