Two-stage superconducting-quantum-interference-device amplifier in a high-Q gravitational wave transducer

We report on the total noise from an inductive motion transducer for a gravitational-wave antenna. The transducer uses a two-stage SQUID amplifier and has a noise temperature of 1.1 mK, of which 0.70 mK is due to back-action noise from the superconducting quantum interference device (SQUID) chip. The total noise includes thermal noise from the transducer mass, which has a measured Q of 2.60× 10...

Superconducting quantum interference device instruments and applications

Superconducting quantum interference devices SQUIDs have been a key factor in the development and commercialization of ultrasensitive electric and magnetic measurement systems. In many cases, SQUID instrumentation offers the ability to make measurements where no other methodology is possible. We review the main aspects of designing, fabricating, and operating a number of SQUID measurement syste...
