Design and development of magnets for HL-2M tokamak

HL-2M is a medium-sized copper-conductor tokamak under construction at the Southwestern Institute of Physics (SWIP). The designed plasma parameters of HL-2M are as follows, plasma current=2.5 MA, toroidal field = 2.2 T, major radius =1.78 m, minor radius = 0.65 m, flux-swing > 14 Vs, plasma pulse ~ 5 s, with a plasma shape of elongation = 2 and triagularity > 0.5. HL-2M coil system is to drive, shape and confine plasma. It includes poloidal field (PF) coils and toroidal field coils (TFC). HL-2M takes advantage of a demountable TFC to facilitate assembly of components inside TFC, resulting in flexibility for experiment and operation and good accessibility to plasma for plasma heating, diagnostic and control. The design and development of the coils are presented.
