Abstract
It is proposed to develop and utilize coils made of high temperature superconducting (HTS) conductor for the purpose of providing magnetic damping for ground- and space-based directional solidification and crystal growth equipment. This innovative use of HTS coils to magnetic damping technology will enable lightweight, variable field magnets to be produced to control the buoyancy- induced convective mixing of the liquid phase which perturbs equilibrium conditions at the solid-liquid interface. The Phase I effort will fabricate a subsize (3" bore) magnet to demonstrate the concept of using HTS coils in this application and lays the foundation for a full size (8" bore) and field (2 kgauss) coil to be fabricated in Phase II.
