LIQUID He3, LIQUID MIXTURES OF He3 AND He4, AND DILUTION REFRIGERATION
John C. WHEATLEYDepartment of Physics, University of California, San Diego, La Jolla, California 92037
Abstract
Basic properties of pure liquid He3 and of dilute solutions of He3 in superfluid He4 are reviewed as they relate to the design and operation of dilution refrigerators. Brief discussions are given both of the intrinsic limitations of the dilution refrigerator and of instabilities which can degrade performance. Finally some characteristics of a new generation of practical dilution refrigerators are displayed and discussed.
