In the arena of global energy technology, China has once again attracted the world's attention with its breakthrough progress. After four months, a new generation of artificial sun "HL-2M" (HL-3) broke out again. In the new round of physical experiments, HL-3 has been put into use for the first time a digital twin system independently developed by the scientific research team of CNNC, which is not only a technological leap, but also a manifestation of China's independent innovation capability in the field of nuclear fusion energy.

1. International cooperation and influence of HL-2M
Since HL-2M was opened to the world at the end of last year, its first round of international joint experiments has attracted the participation of 17 well-known scientific research institutes and universities around the world, including the French Atomic Energy Commission and Kyoto University in Japan. The breadth and depth of this international cooperation not only demonstrates the international influence of HL-2M, but also reflects the recognition and expectation of global scientific research institutions for China's nuclear fusion technology.

2. Technical details and innovative applications of digital twin systems
The application of the digital twin system is one of the highlights of the HL-2M project. By building a digital model in the virtual space that is exactly the same as the physical entity, the system realizes all-round real-time and accurate monitoring of the vacuum chamber baking process. The application of this technology not only ensures the safe and stable operation of HL-2M, but also lays the foundation for the research and development of global intelligent control.
In terms of technical details, the digital twin system takes the temperature field distribution of the vacuum chamber as the core object to build an accurate digital model. By receiving the data input of the heater and the physical temperature monitoring point, and using the virtual sensor algorithm, the complete temperature field distribution is output in real time, which realizes the real-time synchronous calculation and monitoring of the all-round and high-precision monitoring of the internal state of the vacuum chamber, and greatly improves the control and response ability of the vacuum chamber baking process.
3. The international first achievement of HL-2M
In the international joint experiment, HL-2M discovered and realized a special advanced magnetic field structure for the first time in the world, which is of great significance for improving the control and operation ability of nuclear fusion devices. This achievement is not only a reflection of China's scientific research strength, but also contributes Chinese wisdom to the development of global nuclear fusion technology.
4. Future prospects for HL-2M
The successful operation of HL-2M and the first application of the digital twin system mark China's important progress in digital key core technologies. In the next step, the Southwest Institute of Physics of the Nuclear Industry will continue to explore the application of digital twin technology in the field of nuclear fusion, help HL-2M achieve higher parameter improvement, and contribute more Chinese wisdom and strength to the application of nuclear fusion energy.
According to the long-term development goal of China's nuclear industry, by the middle of this century, the application of nuclear fusion energy should be realized. The construction and operation of the HL-2M is an important step for China to achieve this ambitious goal.
Conclusion
The world premiere of the digital twin system of the new generation of artificial sun "HL-2M" is not only a successful practice of China's independent innovation in the field of nuclear fusion technology, but also a strong proof of China's contribution to global energy science and technology. With the continuous maturity of technology and the deepening of application, we have reason to believe that HL-2M will play a more critical role in the future energy field and provide Chinese solutions for solving human energy problems.
