ShareConstruction techniques for adiabatic demagnetization refrigerators using ferric ammonium alum.
Author(s) : WILSON G. W., TIMBIE P. T.
Type of article: Article
Summary
The authors describe techniques used to fabricate the cold storage of an adiabatic demagnetization refrigerator that uses the paramagnetic salt ferric ammonium alum. They discuss the design of a leak-tight housing for the salt as well as a technique for growing ferric ammonium alum crystals that results in a housing filled with more than 98% refrigerant. These techniques have proven to be reliable in creating robust single-stage refrigerators. Similar techniques can be used for the second stage of a dual-stage adiabatic demagnetization refrigerator.
