Binary Josephson Array Power Standard
Based on binary Josephson arrays we plan to develop a system for DC and AC power applications that allows a new representation of the Watt based on the Josephson effect.
Presently it is possible, using binary SINIS Josephson arrays, to synthesize sine waves with calculable rms values and
In a mid-term period a two phase source for the frequency range up to
It is expected that participants in the project have agreed to carry out significant research in this area at their institutes without receiving additional funding from this project. Formal development tasks and objectives in this project have been defined in the framework of EUROMET project 756.
Final Report 2007-12-12
Based on binary Josephson arrays we have developed a system for DC and AC power applications that allows linking representation of the Watt directly to the Josephson effect. First papers have been presented at the CPEM 2006, Turin, Italy, see e.g. [1, 2]. More presentations for the next CPEM 2008 in Boulder, USA, are in preparation.
A paper was presented at the metrology conference in Lille 2007, France, that summarizes most of the investigations of the project . See also references therein.
