Nuclear magnetic resonance (NMR) experiments at ultralow temperatures place high demands on superconducting quantum interference device (SQUID) amplifiers. We have developed a suitable direct-coupled readout SQUID electronics system, which utilizes a

We have designed and constructed a primary thermometry system for operation from 4.2 K to temperatures well below 0.65 K, the bottom of the International Temperature Scale (ITS-90). The system is composed of a thin-film resistive-SQUID (R-SQUID) and

A foundry has been established for production of superconductive integrated circuits, modeled after semiconductor application-specific integrated circuit (IC) production. The foundry supports and improves standardized Nb-based IC processing, and deve

The authors present a statistical model to account for Josephson-junction critical current variability produced in integrated circuit processing. On the basis of data gathered from over a thousand junctions from the TRW superconducting integrated-cir

Niobium carbonitride (NbCN) Josephson circuits can operate over a wider temperature range than either niobium or niobium nitride circuits. Higher operating temperature places NbCN technology more comfortably within the range of closed-cycle refrigera

We present measurements of hysteretic resistive SQUIDs (R-SQUIDs) as a function of the hysteresis parameter β L =2 πLI c / Φ 0 . Varying β L in situ from 15 to 45, we observe quasiperiodic peaks in frequency noise which decrease toward the therma

We are developing a primary thermometer for operation from 4.2 K down to millikelvin temperatures. The principle of the thermometer is to measure thermal fluctuations in a thin-film resistor by transducing them into phase fluctuations in a Josephson

We have developed a 1 MHz bandwidth dc SQUID magnetometer. By reconfiguring the ground reference leads to the SQUID we increase the maximum signal amplitude, and hence slew rate, by two orders of magnitude without altering any other system parameters
