[Explanation] Recently, the first batch of coils and key components of the divertor of the French WEST device at the ITER program calibration site of the International Thermonuclear Fusion Experimental Reactor were completed and officially delivered to France.
The successful development of the important components of these two nuclear fusion devices marks another important new progress in the international scientific and technological cooperation project of the Hefei Comprehensive National Science Center.

ITER is currently the world's largest nuclear fusion device, which embodies the desire of mankind to use fusion energy peacefully. As one of the participants in the ITER project, China has excellently completed the production of many important components in the ITER device.
Today we are here to celebrate the delivery of the first batch of two CC coils (correction field coils) from the Institute of Plasma of the Chinese Academy of Sciences. Although the coil size and volume are relatively small this time, it almost integrates all the keys needed for large-scale superconducting coil manufacturing. science and technology.
[Explanation] It is understood that the correction field superconducting magnet system is one of the important components of the ITER host. It contains a total of 3 groups of 18 coils. The manufacturing process is extremely complicated, involving superconductivity, low temperature, insulation, materials, welding, nondestructive testing, electrical Testing and other interdisciplinary.
The calibration field coil delivered to France this time was developed and developed by the Plasma Institute of Hefei Institute of Material Science, Chinese Academy of Sciences.

In the past ten years, the Institute of Plasma Physics, Chinese Academy of Sciences, as the main supplier of CC coils (correction field coils), has invested a lot of energy and resources in the manufacture and certification of CC (correction field coils). It is certain that, With the joint efforts of all parties, the Plasma Institute has made great breakthroughs in coil winding, helium tube welding, vacuum pressure impregnation, laser sealing welding, and final cold testing.
[Explanation] The WEST device is an all-tungsten divertor superconducting tokamak being upgraded by the French Atomic Energy Commission.
The divertor component is the core component of the WEST device, which plays a key role in its realization of long-pulse high-parameter operation and its main scientific goals.
[Explanation] In recent years, with the continuous deepening and expansion of the comprehensive strategic partnership between China and France, China and Europe, the Institute of Plasma, Hefei Institute of Material Science, Chinese Academy of Sciences and the French Fusion Research Institute have been involved in the development of ion cyclotron antenna and divertor components, and joint physical experiments , Tokamak long pulse operation research and other aspects have carried out fruitful cooperation.
China-France cooperation in the field of fusion research has increasingly become a model of Sino-French and Sino-European international scientific and technological cooperation.

Grasping the important opportunity for the integrated and high-quality development of the Yangtze River Delta, and relying on the Hefei Comprehensive National Science Center, we will further open and share the large-scale scientific installation platform and participate in the international large-scale scientific plan, further strengthen international scientific and technological cooperation and exchanges, and contribute to the development and utilization of fusion energy. Make more contributions.
