作者设计并制作了一个工作在40 K的1 T低温制冷脉冲线圈。采用Bi-2223矩形截面多芯导线组成的4股层间换位平行导线，实现了电流均匀分布，并将交流损耗密度降低到单股的水平。脉冲线圈是一个16层螺线管，内径为52 mm，外径为111 mm，高度为120 mm。AlN板的散热器，这是绝缘体，被安排在层之间的冷却的热量，由于交流损失通过热传导。他们可以连续操作线圈在一个三角波模式，振幅为1 T和频率为1 Hz。交流损耗为10.6W，其他热负荷为13 W。
The authors designed and fabricated a 1 T cryocooler-cooled pulse coil operating at 40 K. A 4-strand interlayer-transposed parallel conductor composed of Bi-2223 rectangular cross-sectional multifilamentary wires was adopted to realize a uniform current distribution and to reduce the AC loss density down to the level of that of a single strand. The pulse coil is a 16-layer solenoidal one with an inner diameter of 52 mm, an outer diameter of 111 mm and a height of 120 mm. The heat drains of AlN plates, which are insulators, are arranged between layers for the cooling of the heat due to the AC loss by heat conduction. They could continuously operate the coil in a triangular waveform mode with an amplitude of 1 T and a frequency of 1 Hz. The AC loss was 10.6 W and the other thermal load was 13 W.
