Design of a Current Source for a Refrigerator-cooled Superconducting Magnet System

With the acceleration and development of superconducting technology and refrigerating technique, the refrigerator-cooled superconducting system has gone to field application from concept design. The current source is an important section of the superconducting magnet system. It affords both of the steady current and reliable protection for the superconducting magnet system. First, the article analyses the working process and the special protecting demands for the current source, then, it suggests a possible scheme and presents a design for the protecting control system by microprocessor.
