A simple He^3-He^4 refrigerator has been designed and constructed. A brief introduction to low temperature physics in general and to dilution refrigeration in particular is given. The properties and theory of He^3-He^4 solutions as they pertain to the design of the refrigerator are discussed. A thermodynamic analysis of the dilution refrigerator is included. The construction of each part of the refrigerator is described in detail. The current status of the dilution refrigerator is presented and future experiments with it are discussed.
