Chapter 422: Ultimate
"Good!" The two academicians showed admiration. Such a young and outstanding scholar can still maintain the original intention of striving for excellence and polish the solidity of the foundation instead of relying on talent to make a great leap into empty construction. What reason do they have not to support him?
The two academicians applauded in their hearts, and felt more at ease about following Wu Tong to work on the project. Although Mr. Wu is young, he is talented, has outstanding achievements, and is calm and reliable!
"The Dongfang Ring has just completed a mission and is currently undergoing a comprehensive cooling and maintenance. It will not be able to carry out a second mission for a while. Academician He, what about SST-1?" Wan Funian analyzed the current situation in China's current tokamak device in a realistic manner.
One is their Oriental Ring in South China, one is the International Thermonuclear Experimental Reactor ITER, and the other is the SST-1 which was just established by the Southwest Institute of Nuclear Physics. There has been no news of it carrying out any mission this year!
"Then let's send the samples to the Southwest Research Institute. We were planning to start an ignition test soon. If we work hard in the next two days, we can still ignite it directly!" Academician He would naturally not lag behind and agreed immediately. Fortunately, they were almost ready and there wouldn't be any big problems if they rushed.
"Thank you for your help, Academician He!" Wu Tong expressed her gratitude and immediately decided that she and Academician He would lead a team, accompanied by core members of the team, to go to the southwest in person to carry out the final material verification and data statistics.
Actually, Wu Tong didn't have to go there in person, but she wanted to experience the ignition of the tokamak device and the current state of the fusion reaction in person, so she decided to go to the southwest in person. A fusion ignition is not easy given the current domestic situation.
Chu Hengyuan immediately wrote it down, "Please confirm the time, Academician He. I will connect the special plane to take you to the southwest. It is not convenient for Mr. Wu to take civil aviation!" Although he is currently in closed research, Mr. Wu's security level has been raised again after he came out into the public this time. Civil aviation cannot guarantee Mr. Wu's safe travel.
"Okay, Chief Chu, I'll contact you when I have made the arrangements!" Academician He agreed with understanding. They knew very well that a genius like Wu Tong, who was almost as good as a nuclear weapon, must be protected!
It just so happened that she had flown there once. Before the trip, Wu Tong and her team prepared some special lithium sheets, which were to be used in experiments to verify the capacity of liquid lithium for neutron recovery. She needed accurate data to fill in the design model of the liquid lithium recovery system. Even with Wu Tong's absolute deduction, she could not deduce without data to rely on, as she was not an omniscient god.
Wu Tong made full use of the ignition test. Academician He laughed at him. Wu Tong was young, but he had inherited the virtue of thrift and diligence from his ancestors.
After confirming the arrangement of materials, Wu Tong handed over the supervision and management of the project to the two academicians. Wu Tong put all her efforts on the breakthrough of the southern gate of the project. She had time to talk to Lu Xiao only after seeing off the two academicians and Chu. The confinement of plasma was also a big challenge.
How to better confine the fusion reaction so that it occurs within the control of the plasma confinement program and minimize the pressure on the first wall.
"Brother Lu, thank you so much!" This is to thank Lu Xiao for his strong support at the meeting and thank Brother Lu for his continued trust in her!
Lu Xiao smiled, "Isn't this as it should be? I have full confidence in President Wu. Isn't this enough that you trust me?"
After a brief chat and reminiscing about the past, Lu Xiao and Wu Tong got down to business. They spent most of their time on the collision of ideas. When two people of the same level communicate, their thoughts work like lightning. What you say, I can understand immediately, and what I say brings you sparks of inspiration. Such a collision is a perfect enjoyment of progress.
"For plasma research, I now have some preliminary design ideas. Let me tell you about them!" Lu Xiao took out his laptop, opened the research and development materials, and began to explain his current breakthroughs to Wu Tong.
The particles in the plasma have kinetic energy. Without a strong binding force, they will move around and spread out.
In fusion reactions, the limited magnetic field cannot give full power and can also bombard the walls of the vacuum chamber, causing the loss of plasma particles and their energy.
Thermonuclear fusion reactions in the sun and other stars rely on gravitational fields to confine plasma. These stars have large masses and strong gravity, which is enough to confine plasma together and carry out thermonuclear reactions.
However, it is impossible to confine the high-temperature plasma on Earth and make it undergo thermonuclear reaction by relying on weak gravity. Other confinement methods must be used.
The main methods of confining plasma in thermonuclear fusion research are magnetic confinement and inertial confinement. There is also a method that can be called the antonym of thermal fusion, which is sometimes used in low-temperature plasma film formation or etching technology to reduce the loss of plasma particles and energy.
However, the technology of low-temperature fusion is currently a difficult barrier. The difficulty is much higher than that of achieving thermonuclear fusion from scratch. It is a technology that only exists and is still a fantasy. Wu Tong made a note in her mind that when she has achieved thermonuclear fusion, cold fusion will be her extended topic.
For Wu Tong, all projects are based on needs and interests. She devotes all her efforts to researching, and the sense of achievement from breakthroughs is incomparable to anything else! Wu Tong likes that in such a field, she reads through peaks one after another, which makes her feel happy and delighted!
"At present, the international mainstream is magnetic confinement, which is a method of limiting plasma to a certain area by using the interaction between magnetic field and plasma. It mainly uses the Lorentz force exerted by the magnetic field on plasma particles, which can make the particles cyclotron around the magnetic field lines and be confined by the magnetic field; the magnetic stress of the magnetic field can exert a macroscopic force on the whole plasma to confine the plasma!
If there is an electric current in the plasma, the interaction force between the plasma current and the magnetic field generated by itself - the pinching force can cause the plasma to pinch, that is, confine it; the magnetic mirror effect can reflect the charged plasma particles whose speed meets certain conditions back in the strong magnetic field area, thereby confining the particles.
Magnetic confinement can only confine plasma in the direction perpendicular to the magnetic field, but cannot confine plasma moving along the direction of the magnetic field lines..." After Lu Xiao's brief introduction, he went on to the key point of his idea.
"Speaking of which, plasma is also a big turbulence problem. I want to use macroscopic quantification to determine a coordinate core to perform plasma calculations. This part of the mathematical model is your forte, Mr. Wu. I need your help!"
