The persistent current switch (PCS) for the superconducting magnet systems in persistent mode is essential. The temperature of the PCS when the superconducting magnet was charged was calculated by heat conduction equations. To verify the analytical results, we have designed and tested the persistent current switch. It operated well on–off switching action with good stabilization. The maximum operating current in persistent mode went up to 60A(at IT). We analyzed the temperature characteristics with respect to heater currents when the magnet was energized. To maintain the temperature over T c in which the PCS is made a state transition, the required heater current was about 120mA. The experimental results were compared with the calculations and they showed good agreements.
