Design and Experiment of Solenoidal Superconduct Magnet Applied to Sodium Electromagnetic Pump

In this paper,solenoidal superconduct magnet which is applying to sodium electromagnetic pressure infuser,then the magnet center B reaches 4.66T when the quench current is 97 A.If reducing the excitation velocity,the center B can reach 5T,satisfying the need of sodium electromagnetic pump.pump is designed in detail and experimentally studied.The room temperature aperture length of this magnet is 600mm,the diameter is 160mm,and the magnetic induction intense in the center field（B） is 5T.The short superconduct thread sample is tested.The critical current is 464 A when the temperature is 4.2K and the B is 5 T,which is larger than the design current.The magnet is quenched training for ten times after reel and vacuum
