Computer-Oriented, Multichannel, Direct-Current, Superconducting Quantum Interference Device.

摘要

We describe the ARC effort leading towards the computer oriented multichannel DC-SQUID system. More specifically, we describe the prototype of lock-in, bipolar preamplifier and flux counter implemented by our team. The results of tests are quoted and show that our CD-SQUID electronics compare favorably with both commercially available BTI-Dynabias and Berkeley readout electronics. More specifically, our system seems to be more user friendly and easier to interface to the computer. (rh)
