Economics of cryogenic systems for superconducting magnets

It is suggested that economics should be considered early in the design phase to permit evaluation of the tradeoffs and options available in the selection of a cryogenic system for superconducting magnets and in the preparation of specifications. This paper describes some of the options which should be considered and examines the impact of these options on operating cost. Component equipment costs are considered, and data are presented which can be used by the designer in making a cost tradeoff analysis. In addition, methodology for an operating cost is presented and examples of typical tradeoffs and their effect on operating costs are reviewed
