球形托卡马克 device in CHINA; data sourced from IAEA 2022 survey.
SUNIST-1 is a fusion device or design surveyed by the IAEA in 2022. SUNIST-1 is the first spherical tokamak built in China in a partnership between National Nature Science Foundation, Tsinghua University and Institute of Physics, Chinese Academy of Sciences. First plasma was produced in 2002 and the machine was subsequently upgraded in 2008.
Purpose
The research objectives of SUNIST-1 are to increase the understanding of toroidal plasma physics with a low aspect ratio and to produce a maintainable target plasma with non-inductive start-up.
