Conduction-cooled superconducting coil using high-thermal conduction plastic having negative thermal expansion coefficient

这项工作是提高超导线圈的稳定性，使用Dyneema纤维增强塑料（DFRP）作为线圈的线轴材料。氮化铝（AlN）作为热沉材料得到了广泛的应用。氮化铝又硬又脆；切割和钻孔都很困难。因此，我们提出了DFRP作为散热材料，并证明了DFRP是有用的。我们通过使用DFRP减少了机械损失，因为DFRP随着冷却而膨胀。

This work is that increase of stability in superconducting coils using the Dyneema fiber reinforced plastic (DFRP) as a coil bobbin material. Aluminum nitride (AlN) has been widely used as the heat-sink material. AlN is so hard and brittle ; it is difficult to do cutting and drilling. Hence, we proposed DFRP as the heat-sink material, and demonstrated DFRP was useful. And we decreased mechanical loss by use of DFRP, because DFRP expanded with cool down.
