Many netizens have heard of China's artificial sun project, and this project is constantly pushing the limits of technology, and China's nuclear fusion technology has made a major breakthrough.
After more than 120,000 tests on the mainland, the Hefei Plasma Research Institute of the Chinese Academy of Sciences, participated in the research and development of artificial solar energy for 403 seconds, which is the same as the increase of a few seconds at the beginning, and now to create a new record, the jump is very considerable, and because of the research and development achievements in this field, it is constantly improving.
A few years ago, the device could only run for 101 seconds in its highly confined mode, but in a few years, this value has doubled, and China's nuclear fusion technology is moving to a higher scientific level.
Is there any concrete significance in the development of nuclear fusion technology for artificial sun?
If a device can be built on the earth that simulates the internal operation and continuous reaction of the sun, it is this kind of nuclear fusion device that will inevitably release huge heat energy and provide huge scientific and technological possibilities for the improvement of the earth's environment for mankind.
The artificial sun project will also participate in the regulation and distribution of natural energy, and provide support and drive for sustainable development in energy-poor areas and areas with insufficient sunlight in mainland China. If this project is successfully developed in the future, it will allow many areas lacking light and energy to truly reap the benefits and convenience brought by the early sun, or will rewrite the maintenance and improvement of the ecological environment, as well as improve environmental protection and upgrading.
At present, nuclear fusion technology is still a long way from the artificial sun that can be used at any time to provide sufficient energy, because it requires a plasma current of hundreds of millions of degrees Celsius, and the challenge is very great, especially since scientists were not even able to find a carrier to carry these high-temperature substances at first. Now scientists around the world have been continuously developing the nuclear fusion project of the artificial sun for 70 years, and although China started late, it has also made unremitting efforts for more than 40 years, and the number of tests has exceeded 120,000 times.
Solar energy provides huge thermal energy, relying on the internal nuclear fusion capacity, and the replication of nuclear fusion technology on the earth faces a variety of difficult technical obstacles. In order to make nuclear fusion matter reach a high temperature of 100,000 degrees Celsius, Yan Zizhong's electrons become the plasma of the atomic nucleus of the legend, but how to maintain such an ultra-high temperature, how to achieve stability, and how to replicate the conditions under which these substances change are all difficult problems in front of scientists.
The first in the world to develop nuclear fusion technology is the Soviet team, the first to create the world's first tokamak container, the use of a closed magnetic field to form such a container, in order to provide a stable environment for nuclear fusion, so that the ultra-high temperature plasma can be lifted by the magnetic field in the air suspended in the state of continuous heating of high temperature, this method has achieved initial results, opening the door to human nuclear fusion technology test. However, because there are many practical difficulties in this technology, how to solve the steady-state fusion reactor is a great challenge. Later, after the collapse of the Soviet Union, this equipment was discontinued, and the project was naturally shelved and no one cared about it, and the international academic community also regretted it.
The mainland is from the 70s of the 20th century began to contact the research of artificial solar nuclear fusion, Hefei Shushan Plasma Research Institute, the introduction of the Soviet Union-built device, and the transformation, so it has the continent's tokamak device, after the test to obtain the continent's first batch of plasma, this improved device, become the continent's first generation of professional equipment for the study of nuclear fusion.
After continuous efforts, the mainland in 2003 upgraded the device renamed the Oriental Super Ring, the volume of this device is relatively large, the height reached 11 meters, equivalent to the height of an ordinary residential building close to three floors, the diameter of 8 meters, it can also be regarded as a huge boiler, because its internal plasma temperature is more than 100 million degrees Celsius, the ultra-low temperature of the superconductor reached minus 269 degrees Celsius, these two people in the world are stunned to hear the extremely high and extremely low temperatures, the distance between the length is 1.2 meters, this is the power of science and technology, can make human indescribable high and cold temperatures, exist in the same container, but also through scientific control means, to maintain a stable state.
Since the completion of the full construction of the Oriental Superring Project in 2006, in the 17 years since then, the scientific research team has continuously solved many professional problems such as super magnetic field and ultra-high vacuum with the spirit of technology research and development, and has made technological breakthroughs to achieve the research and development of nuclear fusion, challenge the value of the limit, and constantly impact the extreme parameter critical point required for nuclear fusion.
In 2021, the continental R&D team was able to achieve a repeat record of 101 seconds at 120 million degrees Celsius, which has since climbed to 160 million degrees Celsius for 20 seconds......
So far, the Oriental Superring Device of the continental nuclear fusion project has been able to build and maintain with high-tech superconducting materials, and realize the strict parameters of superconducting materials reaching the kilometer level, the diameter of the superconducting wire is 0.8 mm and there are no cracks and damages.
So far, the mainland has more than 68 patented technologies in this field, and behind these honors, the scientific research team forgot to sleep and eat, and almost lived in the laboratory and often worked hard all night.
Once this dream can be realized, it will rewrite the history of human energy, and it is expected to enter a new era for energy demand and consumption.
