Summary

The floating coil and persistent current switch (PCS) are wound with silver-sheathed Bi-2223 tapes, and they are operated in the temperature range of 20-40 K. After the basic properties of the main coil and HTS-PCS were examined in a liquid helium cryostat, the coil was installed into the vacuum chamber of the Mini-RT device. The HTS (high-temperature superconductor) floating coil was then cooled by helium gas using GM cryocoolers equipped with detachable transfer tubes. The excitation tests of the coil were carried out by supplying current from an external DC power supply through the detachable current feeder terminals as the HTS-PCS was turned off.
