A Fridge in Space: A Case Study in Thermodynamics

This case analyzes the principles of thermodynamics and the operating cycle of an adiabatic demagnetizing refrigerator (ADR), a piece of equipment NASA uses to keep x-ray detectors cold enough to work.  A synthesis of all the basic principles of thermodynamics, the case would be appropriate for students enrolled in a thermal physics course, typically taught at a sophomore level.
