Author(s) : LIN M. Z.

Type of article: Article

Summary

A VERSATILE, COMPACT, CONSTANT CURRENT-VOLTAGE, BIPOLAR POWER SOURCE FOR QUASI-STATIC OR DERIVATIVE MEASUREMENTS OF THE CHARACTERISTICS OF SUPERCONDUCTING JUNCTIONS HAS BEEN DEVELOPED. THE CIRCUITRY IS BASED ON A NEGATIVE FEEDBACK STRATEGY THAT IS EFFECTIVE IN MAINTAINING CONSTANT CURRENT-VOLTAGE BEHAVIOUR AT THE JUNCTION ITSELF AND ALL LEAD RESISTANCES ARE INCLUDED IN THE FEEDBACK LOOP. CONSTANT CURRENTS AND VOLTAGES CAN BE DELIVERED OF UP TO ABOUT 0.5 A AND ABOUT 0.75 V, RESPECTIVELY.
