| Abstract: | Superconducting magnet technology is increasingly used in manufacture of MRI and NMR apparatus.Quench protection is an issue of great importance for the design of a superconducting magnet system.On the basis of references in the recent years,three aspects,passive or active protection method,protection circuit and quench acceleration are summarized and analyzed.Some commonly used software for quench simulation is introduced and compared as well. |
