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

Abstract

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… (More)
