The development of a program system for the design of superconducting poloidal field coils

Abstract A program system was developed for the purpose of the computer aided design of superconducting poloidal field coils in tokamak fusion devices. The program system consists of a main program, twelve subroutines and three data files. The main program effects the initialization of the program system and subsequent control of the calculation process. The system can be operated both in iterative mode and batch one by modifying it. The subroutines perform the calculation of electromagnetic variables, the structural design of the coils and the estimation of their design solutions. The data files play the role of a data base. The program system greatly reduces the large amount of labor and time required to design superconducting poloidal field coils. Utilizing the data files, users can readily redesign any part of the coils.
