| Research Abstract |
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.
