Abstract :
The experimental results of a cryo-free high-field magnet system for a novel magnetizer are presented. The magnet for the application is a superconducting racetrack coil of 0.7 m length using low AC-loss wire from Luvata. The coil selection, reaction, epoxy selection, winding trials and vacuum impregnation are reported in a previous paper. Here the experimental testing of the prototype is presented. The magnet was cooled down with a 4 K GM cryocooler to its operating temperature and ramped. The behavior during cooldown, ramping and training are presented, demonstrating the viable operation of this low-cost engineering prototype.
