The component development status of HL-2M tokamak

Highlights: • The construction progress of HL-2M as the modification of HL-2A tokamak is introduced. • HL-2M project scope and design schemes show that it is actually a new tokamak. • The main features, design and fabrication of tokamak components are stated. • The construction of tokamak auxiliary systems involved in the project is briefly introduced. - Abstract: HL-2M is a medium-sized copper-conductor tokamak under construction at the Southwestern Institute of Physics (SWIP). HL-2M project will construct a totally new tokamak machine, with other system upgrades from present existing tokamak at SWIP. The project is progressing. The machine components, coils, vacuum vessel, support, etc. are in the stage of fabrication in factories and to be delivered sequentially in next year for tokamak assembly. The scheme of machine assembly has been made. Other components or systems involved go forward into different construction stages. The progress of the component developments is mainly presented.
