Abstract We report on the latest of our Stirling-cycle mechanical cryocoolers. Our coolers are specifically designed to work in the space environment and to meet requirements such as power efficiency, compatibility with sensitive instruments, and high reliability. In this work we discuss a cooler tailored to efficiently provide refrigeration at two different temperatures simultaneously. This protoflight maturity-level cooler delivers approximately 0.4 W of cooling at 35 K and 0.6 W of cooling at 60 K for 80 W of input power from a dc supply. We will describe its general capabilities and some of the peculiarities associated with our approach to controlling two thermal loads with a single cooler.
