Design and Construction of Toroidal Field Coils on HL-2M Tokamak

HL-2M is a middle-sized copper conductor tokamak, which aims to operate close-burning and high-performance plasma for experimental magnetic fusion researches. The magnetic field coil system is an important part of HL-2M machine, consisting of a toroidal field (TF) coil system and a poloidal field (PF) coil system. In the operation of HL-2M, the TF coils operate in the environment of high current, strong magnetic field, and high stress. The structure, electromagnetic, electrical and thermal issues of TF coils were solved in design and construction phase. In this paper, the structure design principle of the demountable TF coils including some key components, was introduced, and then the construction of the TF coils, especially the industry processing, was established.
