Abstract
This paper presents the design and fabrication of a high-Tc superconducting (HTSC) power supply with the Bi-2223 pancake load, as well as its characte ristics as determined through experiments. HTSC power supply consists of tw o heaters, an electromagnet, a Bi-2223 solenoid, and a Bi-2223 pancake load . In this experiment, a 331-mH electromagnet and 0.8-A de heater current we re used, and 8.5 and 17 s were used for pumping periods, respectively. Mech anism of the superconducting switch is used for heater-trigger. In order to measure the pumping-current with respect to the magnet flux changes, a hal l sensor was installed at the center of the Bi-2223 pancake load. The exper imental observations have been compared with the theoretical predictions. I n this experiment, the pumping-current has reached about 0.6 A with 0.01-V electromagnet voltage.
