Optimum dc current resolution for high-source resistances with a dc transformer matched rf SQUID

  • 1. Physikalisch-Technische Bundesanstalt, 3300 Braunschweig, West Germany

Description

By using a cryogenic current comparator with a ferromagnetic core, optimum matching for high-source resistances of up to about 400 kΩ for a commercially available rf SQUID is achieved. This extends the use of SQUID instruments considerably, especially for applications where the source resistance exceeds 10-1 Ω
