Western Superconducting All-Superconducting Tokmak Nuclear Fusion Device Makes Major Breakthrough

A few days ago, "Science and Technology Daily" published "Major breakthroughs in China's science and technology in 2021", and announced ten representative major scientific and technological achievements independently completed by my country's scientific and technological circles in 2021, including the fully superconducting Tokmak Nuclear Fusion Device (EAST), Superconducting quantum computers and large-scale cryogenic refrigeration systems have made important breakthroughs. These directions are also the key areas of Western Superconducting Corporation's focus on research and development. Through comprehensive and in-depth cooperation with relevant domestic superior application units, Western Superconducting has made breakthroughs in related superconducting materials and Low-temperature technology will continue to exert strength during the "14th Five-Year Plan" period to help the continuous development of relevant high-tech technologies and enter the industrialization stage.

The "artificial sun" achieves a repeatable plasma operation of 120 million degrees Celsius for 101 seconds and 160 million degrees Celsius for 20 seconds.

In recent years, Western Superconductor has insisted on focusing on the frontiers of international science and technology, insisting on independent research and development, and has successively developed a new generation of all-superconducting Tokamak fusion devices and high-field magnetic resonance imaging (MRI) core manufacturing technologies for high-performance superconducting wires. The only complete production line in the world that includes superconducting alloy melting and forging, wire structure design and processing and heat treatment. The comprehensive performance of the mass-produced wires has reached the international leading level, supporting the rapid development of my country's large scientific devices and national high-end medical equipment.

CRAFT is the pre-research of the China Fusion Engineering Reactor (CFETR) project, and it is also the first major national science and technology infrastructure approved for construction by the Hefei Comprehensive National Science Center. After completion, it will become an international magnetic field. A comprehensive research platform with the highest parameters and the most complete functions in the constrained fusion field. In 2021, Western Superconductor will undertake the task of manufacturing high-performance NbTi and Nb3Sn superconducting wires for the CRAFT project, comprehensively improve the level of RD and industrialization of low-temperature superconducting materials in my country, and will continue to lead the development of international superconducting tokmak technology for my country. Provide technical support for fusion reactor design and core component research and development, large-scale low-temperature and superconducting technology research, and deep space exploration.

Superconducting quantum computing is the core of the next generation of information technology, and it is also the frontier and hot spot of current physics research. The core element of the superconducting qubit is the Josephson Junction, that is, two superconductors are connected through a nano-scale insulating layer, and the signal transmission is realized through the quantum tunnel penetration effect at a temperature of 100mK. In recent years, Western Superconductor has continued to make efforts to face the high-performance MgB2 ultra-thin film for the application of new superconducting qubits in the future. It has successively developed various types of MgB2 films with nanometer-level thickness, and obtained the magnetometer design and manufacturing technology with thin-film SQUID as the sensor. , Will provide strong support for my country's independent development of superconducting quantum computing and quantum communication research and development and industrialization.

Superconducting technology is an internationally recognized representative of disruptive technology, which can provide a strong guarantee for the sustainable development of human society, and has broad application prospects in the fields of medicine, energy, transportation, and national defense.

During the 14th Five-Year Plan period, Western Superconductor will continue to aim at the international frontier, providing my country's Fusion Engineering Reactor (CFETR), 9.4T full-body ultra-high field magnetic resonance imaging, domestically produced superconducting heavy ion and cyclotron proton accelerators for cancer treatment, and 600 km ultra Provide solid superconducting materials and technical support in the fields of magnetic levitation, MJ-level superconducting energy storage, and integrated superconducting magnetic separation sewage treatment.
