HL-2A (Huan-Liuqi-2A) is a medium-sized tokamak for fusion research in Chengdu, China.{{cite journal|last1=Liu|first1=Dequan|last2=Zhou|first2=Caipin|last3=Cao|first3=Zeng|last4=Yan|first4=Jiancheng|last5=Liu|first5=Yong|title=Construction of the HL-2A tokamak|journal=Fusion Engineering and Design|volume=66-68|year=2003|pages=147–151|issn=0920-3796|doi=10.1016/S0920-3796(03)00165-0|bibcode=2003FusED..66..147L }} 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.{{cite web|url=https://www.ipp.mpg.de/ippcms/eng/presse/archiv/11_02_pi|title=ASDEX – German fusion device now re-operating in China|author=Isabella Milch|date=2002-12-02}} HL-2A was the first tokamak with a divertor in China.{{cite web |url=https://www.siffer.science/Pages/DEVICES/HL-2A.aspx |title=HL-2A |work=SIno-French Fusion Energy centeR |date=2017-11-17}} The research goals of HL-2A are the study of fundamental fusion plasma physics to support the international ITER fusion reactor.
