Abstract
Aim: to determine the operating parameters of the toroidal magnetic field system (operating temperature, number of CORC cables, transport current value) of the MEPhIST-1 superconducting tokamak
Materials and Methods: numerical calculation of the toroidal magnetic field of a tokamak was performed in the COMSOL Multiphysics software
Results: magnetic field distributions were obtained for various values of the transport current flowing through the tokamak coil. The proportionality coefficients between the maximum magnetic field on the coil and the transport current, the operating magnetic field and the operating transport current were determined.
Conclusion: the number of CORC cables required to achieve an operating magnetic field induction of 1 T has been determined: 7 at a temperature of 37.6 K and 6 at a temperature of 33.6 K. It has been shown that it is possible to achieve an operating field value of about 1.5T with 7 CORC cables when the temperature is lowered to 21.1 K.
