Abstract

A small, open-cycle, Joule-Thomson helium refrigerator has been developed, capable of producing 500 mW of refrigeration in the 4°K range. The AC-3L CRYO-TIP® refrigerator* uses liquid nitrogen and commercial gas cylinders of hydrogen and helium as working fluids. It is readily adaptable to a variety of experiments through the use of interchangeable vacuum shrouds and sample holders. Among its characteristics are small size, ease of operation, and rapid temperature adjustability. It also makes 4°K temperatures available to laboratories where liquid helium cannot easily be obtained.
