Abstract

A magnetically levitated superconducting coil device, Mini-RT, is being developed using high temperature superconductors for the purpose of examining a new magnetic confinement scheme of high-beta plasmas. The floating coil has Bi-2223 Ag-sheathed tape conductors, which will be effectively used in the temperature range of 20-40 K. The fabrication of the coil has been completed, and excitation tests of the coil were carried out in a helium cryostat. The coil was successfully excited up to the nominal current with a proper PCS operation.
