Description
Cylindrical thin film dc SQUIDS that make use of resistively shunted Nb-NbOx-Pb tunnel junctions have been constructed and tested. These junctions are very robust: the SQUIDs can be thermally cycled repeatedly and stored at room temperature indefinitely. The weak temperature dependence of the critical current allows SQUID operation at any temperature below about 6K. The resolution is typically 4x10-5 phi0 /√Hz above 2x10-2 Hz; at lower frequencies the noise power spectrum is 1/f. The long-term drift is less than 2x10-5phi0/hr. The 1/f noise and drift are lower than any values reported for other types of SQUIDs. (Auth.)
