A Modified Solvay-Cycle Cryogenic Refrigerator
During the evolution of small cryogenic refrigerators, there has been an interplay between certain applications demanding the development of new refrigerators and the existence of new refrigerators opening the doors to new applications. The Collins helium liquefier is a well-known example of a unit which, when first built, was expected to have a very limited market as a laboratory liquefier. However, the availability of this unique machine generated many new uses that could not have been predicted before it was built. Another example is the Joule-Thompson cooler which was developed for military infrared detector systems, but was soon utilized in a slightly modified form in diverse applications in research laboratories.
