托卡马克 device in CHINA; data sourced from IAEA 2022 survey.
HL-2A is a fusion device or design surveyed by the IAEA in 2022. Built in 2002, HL-2A was the first tokamak with a divertor in China. The tokamak is based on main components (magnet coils and plasma vessel) belonging to the former ASDEX tokamak. HL-2A is located at Southwestern Institute of Physics, China.
Purpose
The key mission of the HL-2A tokamak programme is to address critical physics and technology issues for ITER and next-step fusion devices. The research focuses on radio frequency wave heating, current drive, plasma confinement, turbulent transport, MHD instabilities, energetic particle physics, H-mode and ELM control.
