MISTE Project Scientist Develops Electronics Board for SQUID

Dr. Inseob Hahn at Jet Propulsion Laboratory, Project Scientist for the Microgravity Scaling Test Experiment (MISTE), has published a paper that reports on the design and evaluation of a convenient DSP-based controller for a superconducting quantum interference device (SQUID). The paper, titled "A digital signal processor based dc SQUID controller," has recently been accepted for publication in the April 2001 issue of the Reviews of Scientific Instruments. The authors have applied this new technique to a high-resolution thermometer (HRT) readout system for low temperature experiments. The paper also describes how the DSP controller can be applied to flux counting and to proportional-integration (PI) temperature control.
