| 英文摘要 | Lawrence Berkeley National Laboratory in collaboration with the Institute of Modern Physics has developed a Nb3Sn-based superconducting magnet system for a fourth-generation electron cyclotron resonance source, with a goal of achieving the magnetic field required for operating at the microwave frequency of 45 GHz. The magnet system is composed of one sextupole magnet inside three solenoids of different sizes manufactured from Nb3Sn round wire. Given the high stored energy density and relatively low wire copper fraction, the coils are not self-protected in the case of a quench. The study of the transient following a quench is carried out by means of the lumped-element dynamic electro-thermal program, which includes a detailed simulation of the interfilament coupling losses developing in the wire. Nonlinear effects occurring in the magnet, such as coupling loss and differential inductance reduction, have a significant impact on protecting these magnets. The resulting baseline quench protection strategy based on four independent energy extraction systems protecting the four magnets meets the quench protection requirements. Furthermore, in order to enhance the redundancy of the quench protection system and reduce the peak voltages to ground, the implementation of a coupling-loss induced quench (CLIQ) system is considered. |
