Qi Zhongxing's words made Xu Chuan chuckle in his heart.

He said in a deep voice, "You should have told me earlier. ”

This problem is both serious and serious, as it may lead to the postponement of the project of the 'Nuclear β Radiant Energy Aggregation and Conversion Mechanism'.

But if it's not serious, that's it, because just by improving the performance of the particle accelerator, it can be solved.

The output energy level and stability of linear particle accelerators are insufficient, which is a limitation of the times.

In his last life, he researched this technology in 2025, and now it is 2019, six or seven years have passed, which is enough for the physics community to improve the performance of particle accelerators by one or two levels.

In other words, the performance of the linear particle accelerator used in this life does not meet the requirements, and according to normal development, it will take five or six years to upgrade.

Moreover, this is China, which is much behind the development of domestic particle accelerators compared to Western countries such as rice and Europe.

This is an objective fact that no one can deny.

Han Jin bowed his head and said, "I'm sorry, Professor, we didn't think it was a big problem at first, after all, the linear particle accelerator is really not very difficult in the whole project." In addition, I thought that you were doing your own research, and a project could not be completely dependent on you alone, so I didn't report it. ”

"It's just that no one expected this issue to have such a big impact."

Xu Chuan shook his head and said, "It's useless to talk about this now, let me see the parameters and performance of your customized particle accelerator first." ”

If you want to talk about problems, in fact, he also has problems.

He didn't think it through on this issue. After all, when he was doing this project in California, he was a linear particle accelerator provided by the California Nuclear Energy Research Institute, and because this problem did not occur, he did not pay much attention to the performance of the linear particle accelerator.

After all, in a large-scale cooperation project, it is impossible for him to pay attention to all aspects of the problem.

It's just that he didn't expect that in five or six years, there would be such a big gap between domestic and foreign particle accelerators.

But fortunately, there are still means of remediation, and hopefully it will be in time.

......

Shaking his head, Xu Chuan followed Han Jin and Qi Zhongxing to the Nuclear Energy Research Institute.

Although the performance of the linear particle accelerator in the hand is theoretically not up to the requirements, this is already the best particle accelerator in China.

In the research institute, Xu Chuan flipped through the documents in his hand.

The Nuclear Energy Research Institute has purchased an ion linear accelerator, which consists of an electron cyclotron resonance ion source, a large separation fan cyclotron, a cooling and storage ring, a main ring pipeline, a radioactive beam line, an experimental terminal and other main facilities.

This is not a new piece of equipment, but it was purchased from a national nuclear energy laboratory, and it cost a full 1.37 billion yuan, which is arguably the most expensive one in the entire project.

The linear particle accelerator has a total length of 850 meters, an accelerating electric field of up to 30 megameters per meter, and an operating frequency of 3,500-11,000 MHz.......

In China, this performance can already be said to be the top, even if it is put internationally, it also belongs to the first line.

This kind of thing can be said to be a core treasure in any laboratory, if it were not for the 'nuclear energy β radiation energy aggregation and conversion mechanism' project is a key project of the state, and the research institute that owns this linear accelerator is a state-owned enterprise, Xu Chuan would not have been able to buy this accelerator.

But now, even if this accelerator is already the best in China, it still can't meet the requirements, which is the biggest problem at present.

.......

In the office, Xu Chuan, Han Jin and Qi Zhongxing exchanged solutions to this problem.

There are many ways to solve this problem.

For example, to purchase and re-customize a particle accelerator from abroad, or to promote the development of particle accelerators, improve the performance of today's accelerators, and so on.

But these methods and means will take too long, and Xu Chuan can't wait that long.

At the beginning of this year, he went to the capital and saw the project document for controlled nuclear fusion, which was an opportunity for him, but it would not necessarily wait for him for a long time.

If too much time is wasted on the nuclear waste project, this opportunity may be missed.

This is unacceptable to Xu Chuan.

So we have to find a way to solve this problem as soon as possible.

.....

Xu Chuan frowned and flipped through the information, looking for a solution to the problem.

The project of "mechanism for the aggregation and conversion of nuclear energy β radiant energy" has entered the final stage, and it is almost completed by one foot in the door, but now it is out of the basket.

Although a research project cannot always be smooth sailing, even project postponement is a normal thing, and the above will understand.

After all, this is the constraint of the times, but the hard conditions of particle accelerator equipment do not meet the requirements, and the ideas and concepts are no problem.

Moreover, strictly speaking, the nuclear energy project only started in the second half of last year, and it has only been eight or nine months now, and the nuclear energy project has now entered the point of building experimental reactors, which is quite fast for a large-scale project.

Normally, a project of this level would take at least five or six years to produce results.

But for Xu Chuan, he couldn't accept it.

The delay in the nuclear waste power conversion project will cause many of his subsequent arrangements and plans to be disrupted.

Moreover, facing and solving the problems and emergencies encountered in the project is the ability of a qualified person in charge.

"First of all, we can rule out the purchase or customization of a new linear particle accelerator, not to mention whether the accelerator in other countries can meet the requirements, whether it will be sold, etc., it is too late in terms of time.

Similarly, it is certainly too late to develop superconducting materials now, which will take a long time, and the testing and validation and production cycles will exceed the budget......"

Staring at the structural diagram of the linear particle accelerator in front of him, Xu Chuan thought about a feasible way.

To solve the lack of energy level and stability performance of the accelerator, he has many methods. For example, it is enough to get the superconducting material out and re-design and deploy the cyclotron pipe of the accelerator to increase the energy level and stability of the linear particle accelerator in front of you to the required level.

However, the defect is that the rectification time is too long, and it takes at least half a year to go through the entire process of R&D-production-reset.

And now, he has two months left at most.

It's mid-April, and in mid-June, he has to finish running the nuclear waste power plant.

Not to mention that it will be put into commercial use now, but at least the experimental reactor in front of him needs to be put into use and tested, which is Xu Chuan's bottom line requirement.

"If that's the case, retrofitting the ion linear accelerator in front of you should be one of the most feasible options."

"And what about the mirror control system?"

Xu Chuan thought of the superconducting magnetic mirror control system developed in his previous life when he was researching controllable nuclear fusion, which has a strong effect on the control of ultra-high temperature plasma.

However, the difference is that the magnetic mirror control system at that time was based on the room temperature superconducting material system he studied, but now, is it feasible to use conventional ultra-low temperature superconducting materials?

Xu Chuan is a little uncertain about this, although theoretically, the properties of room temperature superconducting materials and ultra-low temperature superconducting materials are almost the same, but in fact there are some differences.

And more critically, to deploy ultra-low temperature superconducting materials, the space where the linear particle accelerator is deployed needs to be modified to a certain extent.

After all, today's ultra-low temperature superconductivity is generally carried out by liquid helium freezing, although only a part of the area is modified, which is also quite a troublesome thing.

"If we give up the magnetic mirror control, is there a way to increase the energy level and stability of the particle accelerator?"

"Perhaps, I can split this issue into two first?"

Suddenly, an idea came to Xu Chuan's mind.

This is a common method in theoretical science when faced with a difficult problem, which is to break down the problem and then solve it one by one.

Particle instability in a particle accelerator generally occurs when the accelerated particles reach their conversion value through the average energy of a circular machine.

When the turning point occurs when the particles rotate around the ring at the same rate, they exhibit a certain range of energy even though they do not all carry the same energy.

This results in a specific motion of the particles in the vicinity of the transition energy, making them highly susceptible to collective instability.

Just as light and microscopes illuminate the object being observed.

The stronger the beam, the easier it is for scientists to examine the object they are observing.

But intensity comes at a cost, and the faster the speed of light, the easier it is to dazzle your eyes or that the bright light will obscure everything, so that you can't see anything.

It's like driving at night and you're facing a super bright high-beam car, and the closer you get to it, the more you see that there is nothing in sight except the lights. (PS: High beam dog give me sharks!) ）

This instability has been studied in physics for decades, but it has not been fully understood to this day.

Of course, just because the physics community doesn't fully understand this instability doesn't mean it can't be controlled.

For example, proton-driven plasma tail field acceleration, radio frequency cavity propulsion and other technologies can reduce instability to a certain extent.

As a top scientist in the field of high-energy physics, Xu Chuan naturally knows how to solve this kind of thing.

If it is simply to improve stability, he has a lot of ways to do it.

For example, by adding an SMI control tail field at the spiral acceleration chamber node, the control of the particle flow beam can be increased to a certain extent.

Orbit control in linear particle accelerators can also be carried out by deploying multiple strong magnetic mirror hoops.

But in either case, there are limitations.

Whether it is the deployment of SMI to control the tail field or multiple strong magnetic mirror hoops, they are limited to acceleration experiments below a certain energy level, and if the output energy level is too strong, both will lose their effectiveness.

This means that energy levels and stability cannot be obtained at the same time, just as you can't have both fish and bear's paws.

Xu Chuan's headache is here.

If you take care of stability, then the energy level of the linear accelerator will not be able to increase, and the controllable fission rate of nuclear waste will be reduced a lot, which in turn will lead to a decrease in power generation.

[The problem of slow update of new chapters has finally been solved on the app that can change the source, download it here.]

And if you increase the energy level, you can't take care of the stability, and this is even more dangerous.

The runaway particle beam is not the ionic radiation emitted by nuclear waste, but it carries a large amount of kinetic energy, which can cause great damage to the semiconductor materials and protective materials in the radiation gap.

......

"It's a real headache."

In the office, Xu Chuan stared at the design drawings in front of him and shook his head.

After staying here for several days, there have been a lot of large and small exchange meetings, but neither he nor the other researchers have thought of any good way to take into account stability and energy level strength at the same time.

"Whew, let's go out for a walk first."

Shaking his head, Xu Chuan put down the drawings in his hand, pushed open the door of the office and walked out.

It's time to get off work, and groups of workers and researchers walk through the industrial park.

This will be a well-established nuclear energy industrial park, with not only accommodation buildings, but also various rest and entertainment facilities.

Along the way, Xu Chuan saw various entertainment facilities such as basketball courts, table tennis courts, and tennis courts, and there were many people playing against each other.

He wasn't very interested in ball games, but it would be fine, and he was relaxed, so he just found a random place to sit down and watch the group play.

stared at the court for a while, and just as Xu Chuan felt a little bored and wanted to get up to eat, the movement on the basketball court made him stop his movements.

In front of his eyes, on one half court, a basketball happened to be stuck on the edge of the basket.

A group of people who played ball, you look at me, I look at you, trying to jump and try to get the ball down, but the bounce of this half-court golfer seems to be average, and they haven't touched the ball for a long time.

Immediately, someone ran to the other half of the court and borrowed a basketball, apparently ready to smash it.

However, it seems that the first basketball card is a little tight, and after trying it twice, it still has no effect, and then what makes Xu Chuan stunned is that the second ball is also stuck after a while.

Well, now the nature has changed.

Xu Chuan stopped and watched the group of people toss with interest.

To be honest, this kind of basketball card can be taken down by finding a pole or reaching a ladder, but boys who play ball generally ignore these automatically.

And when the second ball is stuck up, their goal is not to get the ball down.

Watching a group of people smash the ball, watching the basketballs get stuck one by one, and finally piling up baskets and finally being smashed down by a basketball as a whole, Xu Chuan suddenly flashed a spiritual light in his mind.

"If you think of this basketball-filled basket as an atomic nucleus and the last ball as a high-energy particle, the nucleus will disintegrate under the collision of high-energy particles to form independent protons and neutrons."

"This process is very similar to the chain reaction of nuclear fission, if you can get enough neutrons, then you don't need a high enough energy level to accelerate the decay rate of nuclear waste, right?"

In his mind, a bolt of lightning suddenly crackled through the mist.

If you can't increase the energy level in a short period of time, then you can increase the number of neutrons.

This is not a collision for experiments, there are strict requirements for energy levels, and high energy levels are just to increase the decay rate of nuclear waste and increase power generation, and there is no need to stumble on the energy level.

Perhaps, I know what to do!

Xu Chuan muttered, and quickly ran towards the office with bright eyes.
