High-Tc DC SQUID system cooled by pulse-tube cooler

Description

We developed a high-Tc DC SQUID system cooled by pulse-tube cooler. To avoid the influence of the wire resistance between SQUID and preamplifier, and to reduce the influence of the temperature fluctuation of pulse-tube cooler, DC coupling between SQUID chip and preamplifier was used and the flux locked loop worked in modulation mode. We also developed a temperature controller, using the DC SQUID as temperature sensor, to control and stabilize the operating temperature of the pulse-tube cooler. With the temperature controller, the DC SQUID system could remain locked for over 8 h
