Abstract
A commercially available complete microprocessor controlled, fully automated 10 Volt Josephson voltage standard system was developed in cooperation between IPHT and Supracon. The system operates with an array of altogether 19,700 SIS Josephson tunnel junctions. A direct comparison between two such systems showed an uncertainty of 2 times 10-10. Furthermore, a novel cryocooler based system is described.
