Development of a Periodic 10 K Sorption Cryocooler

The design and fabrication of a small, closed-cycle, periodic 10 K sorption cyrocooler laboratory system is described. The cooler is designed to provide cooldown from 60 to <10 K in under 2 minutes, maintain a simulated detector heat load of 100 mW below 10 K for over 10 minutes, and have the ability to be recycled in under 6 hours.
