    A relatively simple mathematical method has been developed for evaluating the refrigeration requirements of cooling schemes. A first major reduction in the refrigerator power can be realized by intercepting most of the support heat leak at an intermediate temperature. A second reduction results when this intermediate cooling station is a continuous one; for example, a parallel stream of cold gas. This method of cooling performs close to the thermodynamic minimum refrigerator power. Minimizing heat leak is a trade-off between refrigeration cost and design and construction cost. 5 refs.
