Abstract

We have fabricated and tested two types of SQUIDs. The first, a low inductance stripline device, was characterized using a commercial dc SQUID as a following amplifier. The second type was well coupled to a 0.16µH input coil and was characterized and flux-locked using an ultralow noise room temperature preamplifier. We present device characterization and noise data for both types of devices.
