Institute of Plasma Physics. It is a major national research institution under the Chinese Academy of Sciences dedicated to advancing the science and technology of nuclear fusion. Founded in the mid-1960s, the institute has become a global leader in magnetic confinement fusion, most notably through its pioneering work on the tokamak design. Its primary mission is to develop the scientific and engineering foundations for a sustainable fusion energy future, contributing significantly to international efforts like the ITER project.

History

The institute was established in 1965, initially focusing on theoretical and experimental studies in plasma physics. Its early work was closely aligned with national strategic goals in energy security and advanced science. A pivotal moment came with the construction and successful operation of the HT-7 tokamak in the 1990s, which marked China's entry into the world stage of controlled fusion research. This success laid the groundwork for the ambitious EAST project, which began operation in 2006 and established the institute as a premier fusion research center. Throughout its history, it has maintained strong support from the Chinese Academy of Sciences and agencies like the National Natural Science Foundation of China.

Research and Development

Core research is centered on achieving stable, long-pulse high-temperature plasma confinement necessary for a fusion reactor. Key areas include advanced tokamak physics, development of novel plasma heating methods like ion cyclotron resonance heating and lower hybrid current drive, and pioneering studies on plasma-wall interaction and divertor technology. The institute conducts extensive work on superconducting magnet systems and materials science for future reactors. Its scientists also engage in fundamental studies of plasma turbulence, transport theory, and the development of sophisticated plasma diagnostics, contributing to broader fields like astrophysics and space plasma.

Major Facilities

The flagship facility is the Experimental Advanced Superconducting Tokamak, a fully superconducting tokamak that has achieved world-record plasma parameters. Preceding EAST, the HT-7 superconducting tokamak provided crucial experience and data. The institute also operates the J-TEXT tokamak, focused on magnetohydrodynamics and disruption mitigation studies. Supporting infrastructure includes multiple linear plasma devices for materials testing, a powerful neutral beam injection test stand, and advanced laboratories for superconducting technology and fusion reactor engineering. These facilities form a comprehensive national research platform for fusion energy development.

Scientific Contributions

The institute has made landmark contributions to fusion science, most notably with EAST achieving the world's first 100-second steady-state H-mode plasma in 2017. Its research on long-pulse operation with fully superconducting coils has provided critical validation for the design of ITER and future reactors like CFETR. Scientists have published groundbreaking findings on edge-localized mode suppression and the development of innovative divertor configurations. Its work has been widely recognized in prestigious journals such as Nature Physics and Physical Review Letters, influencing global fusion roadmaps and earning accolades including the State Natural Science Award.

Organizational Structure

The institute is organized into several specialized research divisions, including the Division of Tokamak Physics, the Division of Fusion Engineering, and the Division of Plasma Theory. It houses key national centers such as the Key Laboratory of Photovoltaic Materials and the Center for Magnetic Fusion Theory. Management and strategic direction are overseen by a directorate and scientific committees, with operational support from departments dedicated to engineering, technology development, and international affairs. It also collaborates closely with major universities like the University of Science and Technology of China for talent cultivation.

International Collaborations

The institute is a key Chinese partner in the international ITER project, contributing hardware like correction coils and PF converter systems. It maintains strong bilateral collaborations with fusion laboratories worldwide, including the Princeton Plasma Physics Laboratory, General Atomics, the Max Planck Institute for Plasma Physics, and JAEA. It actively participates in the IAEA fusion energy conferences and coordinates joint experiments under frameworks like the ITER Satellite Tokamak program. These partnerships facilitate extensive scientist exchanges, shared experimental campaigns on devices like DIII-D and ASDEX Upgrade, and co-development of fusion technologies.
