该文中介绍研制的一个脉冲超导磁体,内径6cm,磁场变化率5T/s,磁场峰值4.95T,磁体失超电流达1106A。该磁体设计采用了最佳化方法,节约超导线材30%。分析了磁体的热稳定性及电磁应力,计算与测量了交流损耗,采用了合理的结构与工艺。磁体建成后,进行多次脉冲运行实验,达到了设计指标。 The article describes the development of a pulsed superconducting magnet, an inner diameter of 6cm, the rate of change of the magnetic field 5T / s, the peak magnetic field of 4.95T, the magnet loss of current up to 1106A. The magnet design uses an optimization method, saving 30% of superconducting wire rod. The thermal stability and electromagnetic stress of the magnet were analyzed, the AC loss was calculated and measured, and a reasonable structure and process were adopted. After the magnet was built, several pulse operation experiments were carried out to reach the design index.
