Abstract :
A high gradient magnetic separator (HGMS) used for recovery of waste electric and electronic equipment has been designed and fabricated in the Institute of High Energy Physics of China. It has a warm bore of 200 mm diameter and consists of two superconducting solenoid coils made of epoxy-impregnated NbTi/Cu superconductors. The designed center field is 5 T, and the field gradient more than 36 T/m. The magnet suffered several trainings to reach its designed current of 153 A and stably operated during many charging and discharging. In this paper, the detailed development of this magnet is presented.
