As the world’s first superconducting tokamak, EAST was designed and developed in China, which officially started construction in October 2000 and stepped into operation in March 2007, mainly including the main machine and vacuum, cryogenic system, power supply, diagnosis, heating and other systems. "EAST Auxiliary Heating System" is the second phase of EAST project, which officially started in November 2011 and stepped into operation in February 2015. The legal entity of EAST is Hefei Institute of Physical Science, Chinese Academy of Sciences ， and the construction site is Hefei City ， Anhui Province.

EAST is currently the only  ，perating Tokamak facility worldwide that replicates both the physical parameters and engineering specifications comparable to those of the International Thermonuclear Experimental Reactor (ITER). The successful commissioning of EAST has positioned China as the first nation to master the cutting-edge technology of fully superconducting Tokamak devices of the new generation. Since its commissioning,the facility has successfully addressed critical scientific challenges including high-confinement mode (H-mode) operation, steady-state maintenance, and high heat flux handling - all pivotal for future fusion reactor viability. It has been continuously setting new world records in sustained plasma operation duration through progressive engineering breakthroughs, including the realization of "100-million-degree high-confinement plasma operation for 1,000 seconds", "long-pulse high-performance plasma operation lasting 1,056 seconds", and"120-million-degree plasma operation for 101 seconds". These breakthroughs have propelled China to the forefront of international research in steady-state magnetic confinement fusion.
