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

这项工作是提高使用Dyneema纤维增强塑料(DFRP)作为线圈绕组材料的超导线圈的稳定性。氮化铝(AlN)是一种广泛应用的散热材料。氮化铝又硬又脆，很难进行切割和钻孔。因此，我们提出了DFRP作为散热材料，并论证了DFRP的实用性。DFRP的使用降低了力学损失，因为DFRP随着降温而膨胀。

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.
