An application of finite element method to magnetomechanics of superconducting magnets for magnetic fusion reactors

Abstract The use of superconducting magnets is needed for magnetic fusion reactor designs to make them economically and technologically viable. Several requirements for an application of the magnets to fusion reactors appear still beyond the present level of technology achieved to date while more than 10 years has been spent for the advancement of the magnet technologies. This paper presents a tentative review of basic researchers on magnetomechanics of superconducting toroidal magnets. Hitherto, less attention has been paid to the basic researchers on the instability and vibration characteristics of the toroidal coils because of lack of close relation with the practical design of superconducting magnets. Nevertheless the theoretical description and the experimental verification stated in this paper might be a significant structural concern with deeper understanding of the magnetomechanical behavior of the magnet and with an optimal design of it.
