Abstract :
Several improvements of Josephson voltage standard systems are described. These concern optimized microwave chips for the voltage generation, a new cryoprobe with an attenuation-reduced waveguide and a simplified microwave source. All these improvements contribute to a marketable cryogenic voltage standard.
