An analytical approach to designing a thermosiphon cooling system for large scale superconducting magnets Open
A Thermosiphon cooling scheme is a productive way of cooling large scale superconducting magnets. The absence of active pumping and the availability of the higher heat capacity parameter "latent heat" make this an attractive cooling method…
