“When did we have such high-end technology?”
"What exactly is perfect ignition technology? If there is such a technology, it will directly solve a big problem!"
"Ignition is really important."
"Said to be 'perfect', can this technology achieve deuterium-deuterium ignition?"
"That's unlikely, right?"
"What kind of technology and what is the specific principle?"
"..."
After Teacher Xu nodded and approved Tang Jianjun's statement, the scholars in the audience started discussing. They were really surprised.
The ignition of nuclear fusion is one of the biggest problems.
They couldn't think of any ignition technology that could be called 'perfect', so they couldn't help but discuss it. The scholars who could participate in the meeting all had a high level of ability.
soon.
Some scholars thought of the annihilation force field. "The ignition technology that can be called perfect can only have two directions. One is the superconducting direction. Superconducting technology is used to create unimaginable high magnetic fields, and it is associated with other technologies to achieve ignition."
…”
"The other direction is more likely, which is the strong annihilation force field. The strong annihilation force field can greatly increase the activity of the example."
"I think this technology is likely to be the control of the strong annihilation force field. The current annihilation force field container has a strong annihilation force field on the outer layer. Can it make the strong annihilation force field shrink inward?"
"After the reaction is stimulated, then control the outward diffusion..."
This idea is very close.
Those scholars who do not know about f-rays certainly cannot imagine that a strong annihilation force field can be excited by rays.
Some scholars who know about f-rays know that they are highly confidential and will not say much about them.
Scholars discussed it a lot.
The atmosphere at the venue became obviously lively.
Before the meeting started, most scholars regarded it as an exchange meeting rather than a formal engineering project demonstration meeting, because they were not optimistic about the research on controllable nuclear fusion.
Since most people are not optimistic about it, research on controllable nuclear fusion cannot be carried out.
They only regarded the meeting as an academic exchange meeting.
While coming here to participate in the conference, I can communicate with other scholars and have some fun together with some familiar people.
etc.
It's different now.
A "perfect" nuclear fusion ignition technology solved a major difficulty in nuclear fusion research. They suddenly felt that there was still hope for nuclear fusion research projects.
Many people are also taking it seriously.
The ignition technology of nuclear fusion is indeed very important. It sounds like just ignition, but it is not easy to achieve the ignition conditions.
Ignition is to make the nuclear fusion reaction self-sustaining. The conventional method is to heat deuterium and tritium plasma to more than 100 million degrees Celsius.
In addition to high temperature, high pressure also needs to be provided to increase the probability of collisions between light atomic nuclei.
It is generally believed that to achieve ignition conditions, deuterium and tritium plasma needs to be compressed to about 10^20 atoms per cubic meter, which is equivalent to compressing one kilogram of material to the size of an egg.
If it is a reaction between deuterium and deuterium, the ignition requirements are even higher, and the lowest temperature required is one billion degrees Celsius.
Scholars heard about the new technology and felt confident.
After the venue became a little quieter, Tang Jianjun continued to talk. He skipped the ignition technology and talked about "Magnetic Field Environment Creation and Reaction Control".
This question contains a lot of content.
If we make a simple summary, it can be understood as an argument for achieving energy output greater than input.
Another major difficulty in controllable nuclear fusion is to 'achieve output greater than input'.
This is also the basic engineering goal of nuclear fusion research. Only when the goal of output being greater than input can be achieved can all research and discussions be meaningful.
The research on "achieving output greater than input" can be traced back to the wson criterion proposed in the 1950s.
This is related to the tokamak device.
In the complete magnetic confinement environment of a tokamak device, the strength of the magnetic field determines the upper limit of density and temperature, and the size of the device determines the upper limit of confinement time.
So whether the output can be greater than the input, the decisive factors are 'magnetic field strength' and 'device size'.
The "Magnetic Field Environment Manufacturing and Reaction Control" that Tang Jianjun talked about is an explanation of the existing basic technologies, including superconducting materials, first-order iron materials and corresponding materials that support the production of high magnetic fields.
In short, the key lies in the material.
The scholars in the venue all understood. Simply put, with the support of first-order materials, superconducting material technology has been greatly improved and can create higher intensity magnetic fields.
In addition, the manufacturing technology for magnetic field generation has also been improved.
Regarding the research and development of advanced superconducting materials, Tang Jianjun only gave a brief introduction. After all, he is not an expert in the field of materials.
After Tang Jianjun finished speaking his part, he left time for Zhao Jiarong.
Zhao Jiarong is the deputy director of the Superconducting Materials Research Center. He introduced the latest results of the Superconducting Materials Research Center.
"Our research has discovered a new type of superconducting material, named cwf-021. This material can carry a very high current, which is about three times that of niobium-titanium alloy."
"In addition, through a series of experiments, we believe that replacing the carbon element with first-order carbon will give cwf-021 a stronger melting point and toughness."
"Research is still ongoing in this area..."
"..."
The report given by Zhao Jiarong was also very shocking.
The superconducting materials used in many strong magnetic field generating devices are niobium-titanium alloys. The upper limit of current intensity carried by niobium-titanium alloys is very high, which means that the intensity of the excited magnetic field is high.
Now a new material has been developed that can carry an upper limit of current intensity that is more than three times higher than that of niobium-titanium alloy, which means that the magnetic field intensity that can be created will be much higher.
This material technology breakthrough can lay a solid foundation for nuclear fusion research.
After Zhao Jiarong finished his report, the venue gave the scholars a break for discussion, and then Wang Hao walked onto the stage with everyone's attention.
This chapter is not finished yet, please click on the next page to continue reading the exciting content! The venue suddenly became quiet.
Many people are looking forward to Wang Hao's speech. Wang Hao is definitely one of the project leaders and the most influential scientist in the world.
They all wanted to know what Wang Hao would say.
Wang Hao was also prepared to speak. A ppt appeared on the big screen, but the title only had four words - "Reaction Vessel".
"All I'm talking about is the reaction vessel."
"Everyone should know that the nuclear fusion research we are demonstrating will use annihilation force field technology. The annihilation force field technology combined with the tokamak device is the most suitable container for nuclear fusion reactions."
"However, many people have a very superficial understanding of this, so I will explain it seriously here."
Wang Hao quickly entered the topic, "The strong annihilation force field we created uses magnetic interference in the outer layer, which is similar to the magnetic confinement method of tokamak..."
“This magnetic interference method can also be used in conjunction with the magnetic generation device of a tokamak.”
"That is, it is a set of magnetic field equipment that can be used to interfere with the strong annihilation force field and can also be used to constrain the internal nuclear fusion reaction."
"That's one of the things."
"Also, we don't need complete magnetic confinement of the tokamak..."
He got to the point.
When these words are spoken, many scholars' eyes widen. International research on nuclear fusion focuses on tokamak devices, and tokamak devices perform complete magnetic confinement, that is, the spiral magnetic field forms a closed loop.
Now Wang Hao says that there is no need for ‘complete magnetic confinement’, which is equivalent to saying that there is no need for a ‘closed-loop magnetic field’.
This is a completely new technical theory.
Wang Hao said seriously, "My idea is to use the magnetically constrained space as the main output end of the device. If there is a magnetically constrained space, it will definitely bear a lot of pressure."
"However, there is an anti-gravity field inside the device."
"Everyone knows that a strong antigravity field can reduce particle activity by up to twice, and the reaction speed can be reduced by three or even four times."
"In this way, we can control the rate of internal fusion reactions by adjusting the strength of the internal antigravity field."
