Abstract :
The development of a compact, portable 10 V Josephson calibration system is described. Its accuracy at 10 V is expected to be 0.02 ppm. Its weight and volume are reduced by more than a factor of three compared to laboratory systems. The new system will replace travelling voltage standards used within several NASA and DOE standards laboratories.
