Tech Spotlight: Improved Micro Cryogenic Cooler

A cryogenic cooler is an instrument used to cool devices to very low temperatures to attain low thermal noise, high system bandwidth, or achieve a super conducting state. Micro cryogenic coolers (MCCs) have drawn a lot of attention recently due to their small volume and fast thermal response. A research group at the University of Colorado and NIST has developed a novel MCC concept that provides unparalleled advantages to current MCCs and thermoelectric coolers in high-sensitivity devices, such as sensors. Their design minimizes volume, increases the heat-exchanging surface, and enhances thermal isolation.
