Abstract:

   This study covers the design of an adiabatic demagnetization refrigeratorfor use in zero gravity.  The most important element in the study is a combined precooler/heat
switch for cooling the paramagnetic salt during magnetization.  The precooler reduces
the required magnetic field and simplifies the design of the system.  The Phase II
effort is a demonstration of the concepts developed in Phase I.
