Chapter 489 Helium 3 Atom Probe (Subscribe)

Helium 3, is a helium isotope gas, the gas is colorless, tasteless, odorless and stable gas!

Of course, what makes helium 3 most famous is that it is the key fuel for controllable nuclear fusion.

In the 21st century, there was a frenzy of moon landing plans, because helium 3 is the key fuel for controllable nuclear fusion, which is equivalent to oil in the future era. Whoever seizes more helium 3 resources will have more say in future energy.

Because helium 3 is brought by solar radiation, and because the earth’s magnetic field is relatively strong, only a few can penetrate the earth’s magnetic field and come to the earth. The accumulated helium 3 reserves on the earth for billions of years are only a few hundred kilograms, which can be mined It is estimated that the used one is less than [-] kilograms.

The moon is different. The moon has abundant helium 3 resources, which are evenly distributed on the moon, with a total of more than 100 million tons of helium 3 resources!

It is precisely because of this that the current controllable nuclear fusion experiments in various countries in the world form helium 3 through the reaction of deuterium and tritium, and then carry out nuclear fusion reactions.

For Huaxia, this is also a step that must be taken. Without the powerful energy provided by controllable nuclear fusion, it is undoubtedly impossible to extract helium 3 from the soil on the moon.

嫦娥5号废了九牛二虎之力，也无非从月球带回10公斤的月壤，而这一次性带回10公斤月壤已经算是量很大的。而月壤中的氦3含量，大概1吨月壤只能提炼4—5克氦3，10公斤的月壤能够提炼的氦3简直是可以忽略不计。

Therefore, the "Golden Crow Device" designed by Qin Yuanqing must first react tritium and deuterium to form helium 3, and then carry out nuclear fusion reaction with helium 3.

The phenomenon of plasma fluid involved in this is a difficult problem. How to ensure the stability of materials in such a complex energy reaction is also a top priority.

The high temperature generated by nuclear fusion is as high as 5000 million degrees Celsius or even 5000 million degrees Celsius. No material can withstand such a high temperature.Therefore, from the beginning of research on controllable nuclear fusion, scientists never thought of developing a material that can withstand high temperatures of [-] million degrees Celsius or even [-] million degrees Celsius.

From the very beginning, the idea of ​​controllable nuclear fusion is to constrain the fusion high-temperature region through a magnetic field, so that the device material does not come into contact with the fusion high-temperature region. At this point, whether it is a tokamak or a stellarator, or the "Golden Crow" designed by Qin Yuanqing devices', are essentially the same.

The tokamak uses the optical pressure generated by many laser beams uniformly distributed in various angles in space to bind the nuclear fusion material in the middle.The stellarator uses a circular electromagnetic field to confine the fusion material in a ring, so as to achieve the purpose of confinement.

The reason why the controllable nuclear fusion experiments of the two devices are still in the era of seconds is that neither the tokamak nor the stellarator can guarantee the effective confinement of the fusion nuclear fuel during the nuclear fusion process.Maybe nuclear fusion can be maintained for a period of time at first, but in the middle and late stages, it will definitely become chaotic!
The "Golden Crow Device" designed by Qin Yuanqing is actually shaped like a gossip, with the two fish eyes in the middle constantly reacting, and the high temperature is limited in the shape of the gossip, so that in this strong magnetic field, the high temperature will not directly contact the device material. Contact, so as to ensure the occurrence and continuation of the reaction.

However, this device requires He3 atom probe technology to ensure that the reaction in the reaction device can be detected at any time.

In the cutting-edge research field of theoretical physics, for an unpredictable chaotic system, it is more common to throw a particle into it to explore the path.By observing the particle, the system is observed indirectly.

The key fuel for the controllable nuclear fusion in the device is helium 3, not deuterium or tritium. The reaction between deuterium and tritium is to form helium 3, and helium 3 is the nuclear fusion reaction, so the detection of helium 3 is the real key.

Furthermore, the atomic diameter of helium-3 is small enough, and the nuclear structure is stable, which not only avoids indistinguishable polyatomic collisions as much as possible in the sense of probability, but also makes it easier to pass through the plasma.

It is of great significance to observe the helium 3 atom through the He3 atom probe. The observation of the helium 3 atom can also be used to spy on the situation of the nuclear fusion reaction.

"Set a palm-sized target material on this device to capture the helium-3 particles emitted from the atomic gun, and then record the electromagnetic wave signals emitted by the collision of helium-3 and tritium atoms during the launch cycle, and the final impact of helium-3 on the target." The data carried by the material such as energy and impact angular momentum, etc., indirectly analyze the data carried by the plasma under high temperature and pressure!" Qin Yuanqing put forward his own ideas, then compiled them into documents, and handed them over to a professional team for research and experiments.

And this team, itself from Shuimu University, is already the top in the country, whether it is the advanced level of experimental equipment or researchers, it is the top in the country!
Only when enough data is accumulated in the experiment, can Qin Yuanqing establish a corresponding mathematical model based on the big data and make further judgments.

The controllable nuclear fusion project involves not only physics-related fields, but also chemistry, mathematics, etc. It is because there are enough disciplines involved that the entire project employs more than 5 researchers.

Each technology is either carried out by one team or by multiple teams, and each technology has a dedicated technical person in charge. These technical leaders are undoubtedly world-class scientists and are among the Chinese scientists. elite.

It is precisely because of this that Qin Yuanqing is confident that he can complete the accumulation of controllable nuclear fusion in the laboratory stage within 4 to 5 years, declaring that Huaxia has mastered controllable nuclear fusion technology.

Otherwise, relying on him alone, it will take at least 20 years to achieve controllable nuclear fusion!

Qin Yuanqing is not keen on ITER because he is not optimistic about ITER. This project started in 1985 and wanted to build the first experimental fusion reactor. He hoped to build an experimental reactor in 2010 and achieve a power output of 1500 megawatts. And the cost was $100 billion.But from the very beginning, ITER was full of ups and downs, especially when the United States withdrew midway in 2000, which made ITER almost aborted.It wasn't until 2003 that as the energy crisis intensified, countries began to pay more attention to it. In particular, China announced that it had joined the ITER program, which prevented ITER from being stillborn, and even the United States returned to the ITER program.

But even if China is such a powerful force, since the ITER project was officially approved in 2005, the cost has increased from the original 100 billion US dollars to 120 billion US dollars, but the original plan was to fully complete the reactor in 2015, but the ITER plan has been postponed. failed.

In Qin Yuanqing's view, controllable nuclear fusion technology requires a powerful country to invest huge sums of money and persevere in overcoming difficulties before it can truly gain traction.If it is an organization with multiple countries participating, people are not aligned, each has its own interests, and there is no scientist with enough prestige to act as a coordinator, it is simply impossible to achieve line-of-sight controllable nuclear fusion!
So far, there has never been a multi-national cooperative organization that can truly build such a super project.

This is also Qin Yuanqing's push for a controllable nuclear fusion project, which was carried out by Huaxia investing huge sums of money and mobilizing huge manpower and material resources, because of this!
On the other hand, after receiving the documents from Qin Yuanqing, the teams responsible for the research on the He3 atom probe technology started researching one after another.

"It's really unbelievable. A probe called helium-3 is inserted into the plasma, and its volume is only as small as an atom!" A young researcher was stunned.

Their research team has just been formed not long ago, specializing in He3 atom probe technology. When they first saw the name of this technology, they felt inexplicable. After all, it was unheard of, and how to start?

The key is that the funding for this He3 atom probe technology is very high, as high as 1000 million RMB for scientific research.

This is their team, no matter which researcher they are, has participated in the most research funding.

"It sounds difficult and unbelievable, but I believe Academician Qin will not slap his head at will. What we have to do is to conduct experiments according to Academician Qin's plan to realize this He3 atom probe technology!" This technology The person in charge is a scientist named Lin Yingming, who is 56 years old and has just been elected as an academician not long ago.

Lin Yingming was born in Shuimu University. After graduating from Shuimu University, he went abroad to study and obtained a doctorate. After working in Princeton University for a period of time, he returned to teach at Shuimu University in 2011. He watched Qin Yuanqing forge a godhead with his own eyes. For Qin Yuanqing He is no different from other young people, he belongs to Qin Yuanqing's brainless fan.

He is very clear that once this He3 atom probe technology is successful, it will undoubtedly be a Nobel Prize-level invention!

The Nobel Prize not only rewards great theoretical discoveries, but also rewards those major inventions that change human civilization.

And there is no doubt that once this He3 atom probe technology is successful, it will promote the development of the entire controllable nuclear fusion project!Considering that Shuimu University has produced a number of Nobel Prize winners in recent years, as the person in charge of this technology, he is undoubtedly very likely to be elected as a Nobel Prize winner!
After all, at the top, Qin Yuanqing has announced that he will no longer participate in any award selection, so the honor will naturally go to the people at the bottom.

Thinking that he might win the Nobel Prize, Lin Yingming's pupils became brighter and more excited.

This kind of thing that can gain both fame and fortune cannot be obtained by burning incense and worshiping Buddha.

Lin Yingming led the team and began to study this He3 atomic probe technology, while Qin Yuanqing continued to improve the "Golden Crow Device" while paying attention to the He3 atomic probe technology. After all, the nuclear industry group will enter the site and start construction in 2022 Construction, he must complete the 'Golden Crow Device' before this, otherwise there is no way to start the construction of the device.
