HL-2A (Huan-Liuqi-2A) is a medium-sized tokamak for fusion research in Chengdu, China.[1] It was constructed by the China National Nuclear Corporation from early 1999 to 2002, based on the main components (magnet coils and plasma vessel) of the former German ASDEX device.[2] HL-2A was the first tokamak with a divertor in China.[3] The research goals of HL-2A are the study of fundamental fusion plasma physics to support the international ITER fusion reactor.
