A High Field Magnet Combining Superconductors with Water-Cooled Conductors

The term “hybrid” magnet has been coined to describe coils in which part of the field is generated by superconductors and part by non-superconductors. Such systems have the advantage in that they can produce higher fields than can be produced by either of their parts alone. In addition, they can represent a rather economical approach to very high fields for laboratories that already possess either power supplies or refrigerators of reasonable capacity.
