Abstract
This article describes a 2-watt, 4-K helium refrigerator using the Gifford-McMahon/Joule-Thomson cycle. The unit features a removable displacer cylinder and high-efficiency, low-pressure-drop heat exchangers. These improvements result in a 100 percent increase in cooling power over the existing DSN system. The effects of heat exchanger efficiency and Gifford-McMahon expander performance on refrigerator cooling capacity are also discussed.
