Description

A magnet consisting of five no-insulation (NI) double pancakes (DPs) has been constructed and tested. In this paper, operating currents in each excitation mode were optimized to achieve the highest magnetic field and three excitation modes of the magnet have been conducted in 77 K to compare. Test results showed the central magnetic field increased by multiple sources. Charging performance and electrical-magnetic transience of NI DPs have also been measured and analyzed. Finally, experiments in this paper verified the feasibility of using multi-flux pumps as DC power supply for MRI magnet consisting of NI coils, which greatly reduces the cost of charging and improves the central magnetic field.
