Abstract :
We have optimized a sensitive SQUID measurement system for use in a space flight experiment in the presence of significant interference from other sub-systems and the perturbing effects of EMI and thermal fluctuations. We will describe developments including a sapphire carrier for the SQUID chip, a precision temperature controller for the SQUID, control electronics with high bandwidth and enhanced thermal stability, and special shielding and filtering techniques used to increase EMI resistance.
