| 摘 要： | 给出了一种利用薄金属带构造的、能够产生周期会切磁场的空气芯电磁铁的设计方案,研究了该类型电磁铁产生周期会切磁场的规律。结果表明,通过增加电磁铁的周期长度,减小电子束通道的高度,或在金属带自身的电阻性发热所能承受的范围内增大金属带上传输电流的线密度,都可以提高电磁铁的励磁强度。增加电磁铁的周期长度,还可以提高周期磁场轴向分布的均匀性。

| Abstract: | The periodic cusped magnetic fields generated by a kind of air-core electromagnets made of thin metal sheets have been investigated analytically and numerically. The amplitude of the PCM fields can be increased through increasing the PCM period, decreasing the magnet gap, or increasing the linear current density in the metal sheets. In addition, the increase of the PCM period will lead to better uniformity of peak-to-peak magnetic fields on the axis z. |
