✦ Synopsis
He II cooling systems for superconducting magnets can be designed using a comprehensive end-to-end numerical model. This model is based on the well-established two-fluid physical model of He II, and automatically takes into account the interactions between the different segments of a practical system. Four classes of He II cooling system are identified which differ in the heat transport mechanisms used and in the means used to suppress boiling. Self-driven circulation loops, in which the heat removed drives He II flow, are compared with zero-mass flow heat pipes for Astromag and for a large ground-based magnet system, and factors affecting the trade-off are discussed.
