摘　　要：研制并实验测试一台65T脉冲强磁场磁体。磁体线圈采用14层纯铜导线与Zylon纤维交替缠绕而成,内绕组采用分布式加固技术,实现应力分布的优化,外层由不锈钢套筒与碳纤维加固。内外绕组分别采用两种不同横截面导线平衡能量分布,实现内外绕组温度分布相对均匀,避免局部过热。磁体孔径为12mm,高为120mm,通过1MJ/3.2mF/25kV高储能密度电容器供电,在20.6kV电压时,获得了磁感应强度为65T、持续时间为20ms的脉冲磁场。Abstract：A 65 T pulsed magnet has been manufactured and tested. The magnet coil consists of 14 layers of pure copper. Each layer of copper wire is reinforced with a layer of Zylon fiber composite. The thickness of the Zylon layer in the inner section is optimized so that the stress is even. In order to balance energy distribution and avoid overheating, two different cross-section copper wires are used in the inner and outer sections, respectively. The coil is 120 mm long with a bore of 12 mm diameter. Its power is supplied via a 1 MJ/32 mF/25 kV high density capacitor bank. At 20.6 kV voltage, 65 T field with a pulse duration of 20 ms was obtained.
