Technology: The naughty kid ruined my college entrance examination, but I turned over to nuclear fus

"Yes, this interferometer and spectral emitter, are the latest ones used internationally, and the quality is very good."

"It seems that this time the laser research center has laid down blood to give us good things."

Lu Yu came to the machine, and after looking around, his eyes were full of satisfaction. According to his inspection, these instruments sent over are basically the latest models, without such crude products, especially the more important scientific research instruments, such as interferometers and emission spectrometers, are the latest international styles.

Don't think that as long as it is an instrument, it can be used.

In today's rapid development of science and technology, the requirements for equipment in every scientific research experiment are increasing day by day, if you have enough excellent scientific research equipment, you can greatly reduce the possibility of accidents and improve experimental efficiency.

In the course of the research of plasma laser cannons....

An interferometer is a device used to measure the density and pressure of heavy hydrogen plasma, which can use the interference phenomenon between the laser beam and the plasma to obtain information such as its phase difference and refractive index.

The type and performance of the interferometer determine the accuracy, sensitivity, resolution and other parameters of the measurement, which affects the diagnosis and analysis effect of plasma.

Lu Yu and his team used a high-resolution interferometer based on the Mach-Zendel interferometer, which can measure the density and pressure distribution of heavy hydrogen plasma to add strength to the next experiment!

"Yes, you guys start this emission spectrometer first, it will come in handy soon."

After looking around, Lu Yu set his eyes on the emission spectrometer sent over.

"Yes, Chief Engineer Lu!"

After receiving the order just issued by Lu Yu, everyone also instantly focused all their attention on the emission spectrometer, and a few people divided by two by three, and then started the machine according to the strict method!

In the next research work, this thing should also play a major role!

Emission spectrometer, as the name suggests, is a device used to measure the temperature and composition of heavy hydrogen plasma, which can use the spectral signal emitted by the plasma to obtain information such as its wavelength and intensity.

A good emission spectrometer can determine the accuracy, sensitivity, resolution and other parameters of the measurement, thus greatly affecting the diagnosis and analysis effect of plasma!

Lu Yu and his team use a highly sensitive emission spectrometer based on a multi-channel fiber optic spectrometer, which can measure the temperature and composition distribution of heavy hydrogen plasma, so that the control plasma can always be controlled at a stable value, not easily out of control!

"Next, we split into three groups."

"The experimental content of the first group is laser generation and heating, the second group is responsible for plasma confinement and emission, and the third group is responsible for plasma diagnosis and analysis."

"When all three groups are completed, we will integrate and test the system in a unified manner."

Lu Yu ordered.

According to his previous ideas, he roughly divided the whole team into three groups according to experience, age, and major.

There are many capable people in their exoskeleton equipment team, and many of them have a lot of research in related fields, so there is no need for Lu Yu to specifically ask for people from the laser research laboratory.

Of course.

Intellectuals like Su Xiaoxiao, who specialize in biology, have little understanding of other disciplines.

This part of the people, Lu Yu's task for them is also very simple, that is, to hold themselves to "do miscellaneous", within some ability, to do something they are good at!

"Okay, is there anything else you want to say?"

Lu Yu looked around, his gaze swept over the researchers, and asked before the research officially began.

"No, we're all ready!"

"Chief Engineer Lu, we can start the experiment at any time!"

One by one, the researchers said confidently.

"Good!"

A look of satisfaction flashed in Lu Yu's eyes, and he waved his hand and said: "

That is too ritualistic thing, we won't engage in it, everyone come on!"

Kyoto, a new project of the Institute of Exoskeleton Devices is in full swing.

The other side...

"Husband, did you really negotiate with them?"

"They agreed to travel with us?"

"Really fake?"

Aunt Wang looked at her husband in disbelief and asked repeatedly.

"Of course it's true, so I say, some things aren't so scary!"

Aunt Wang's husband said with a confident look:

"That's it. The point is that you still have to put down this face. You see, I came over with two cases of wine today, the atmosphere was not very pleasant, I also had a few drinks there, Meizizi, Meizi hahaha. A

smile appeared on his face, as if recalling the taste of noon wine.

"The smell of alcohol! Just know you're drinking!

Aunt Wang covered her nose with a look of disgust and looked at her husband:

"Let's not talk so much nonsense, let's be serious, when is our family going to leave?"

"You should take the leave, right?"

"Don't worry, wife! It's useless for my unit to accumulate so many years of leave, isn't it just waiting for this kind of time?

Aunt Wang's husband smiled and said

, "Anyway, I think things should be sooner rather than later,

and we don't need to delay it too long."

"Or not.... Just this week, right?

"I'll go talk to their family then, and then the four of us will leave early, what do you think?"

"Okay."

Aunt Wang thought about it and agreed with the idea.

"Then when we get to Kyoto, how will we arrange?"

"What else can be arranged, when I get to Kyoto... Of course, it's okay to go to some attractions together, but let's not interfere with what people play.

Aunt Wang's husband instructed in a serious manner:

"Just like if you let your family go to the NPC with us and see our baby, people will definitely not want to, right?"

"Uh-huh, I know, I'm not the kind of person who doesn't understand weight!"

Aunt Wang waved her hand and said a little impatiently:

"Since you have such a good relationship with their family, then I will continue to go by you tomorrow, okay?"

"Okay, I'll go, I'll go!"

Aunt Wang's husband nodded and said.

---

not only Aunt Wang's family was discussing going to Kyoto, but Lu's mother and father Lu were also discussing this matter at home.

"You say.... When we arrive in Kyoto, shall we contact Xiaoyu?

"Definitely! If we don't contact Xiaoyu as soon as we get to Kyoto, he will definitely be worried! Besides, if you don't contact our son, you don't know anything when you go to Kyoto, why don't you know, really think we are also going on vacation?

Father Lu said.

"Okay, then we'll contact Xiaoyu when we arrive."

"As for what to do at that time, it is all arranged by whispering!"

Lu Mu said.

Regarding the trip to Kyoto, the two finally had some plans.

Long University of Science and Technology, Lu Yu, the Exoskeleton Equipment Research Center

, walked around for a while and came to the place of Group A.

"How, did you encounter any difficulties?"

He asked with a look of concern.

"With

the direction program you gave us before, at least in the general direction, our side has been progressing smoothly."

The leader in charge of the research task of Group A said seriously.

The task of their group A was simple, to test the generation and heating of the laser. Before the official test began, Lu Yu had already informed them of the general direction of the entire research group's mission.

First, Group A needs to design a suitable laser source that can efficiently emit a high-power, high-frequency, high-quality laser beam and be precisely focused on the heavy hydrogen target.

Only in this way did there be a prototype of a plasma laser cannon!

If there is not even a stable high-power laser beam, how can it be called a laser cannon?

In the period just now

, after many tests and comparisons, Group A finally chose a solid-state laser based on titanium gemstone crystals, which can produce ultrashort pulse lasers up to a few microseconds, with a power of several hundred megawatts, a frequency of several hundred hertz,

and a mass factor close to 1.

They also use some high-performance optics, such as lenses, prisms, beam splitters, etc., to adjust and control the direction, shape, phase and other parameters of the laser beam.

Now, their final step is to assemble these devices into a complex optical system, mount it on a precision mechanical platform that can be adjusted and calibrated at any time!

In the general direction, Group A did not encounter any problems, but at this step... Group A encountered a lot of trouble.

How to combine the optical path system of lens, prism, and beam splitter to control the size so that it can be smoothly carried by exoskeleton equipment?

"Chief Engineer Lu, we are a little stuck here for the time being."

"But you give us time, we should be able to solve this problem!"

The leader of Group A said with conviction.

"Well, I'm sure you can solve this problem, but..." Lu

Yu hesitated, but still said:

"Let me see the logs of your several rounds of experiments first, let me try to see if I can give you some inspiration."

"Yes, Chief Engineer Lu."

The team leader did not hesitate, and directly put the specific experiment log of several laser launches in front of Jiang Yi!

Above, the complete experimental data is recorded!

"In fact, to put it bluntly, everything is inseparable, following the principle of E = P * τ. What we have to do is to reduce the laser mass factor (M2) as much as possible and let it be infinitely close to 1, only in this way can we maintain the quality of the laser while minimizing the optical system..."

Lu Yu patiently taught.

If the laser beam is continuous, then the relationship between laser power and energy is: E = P * t.

If the laser beam is pulsed, then the relationship between laser power and energy is: E = P * τ, where E is the energy of a single pulse, P is the peak power, and τ is the pulse width.

They used a short-pulse laser in group A, so they used the second formula calculation!

The laser mass factor (M2) refers to the degree of difference between the actual laser beam and the ideal Gaussian beam, which reflects the divergence angle and focusing ability of the laser beam, and the M2 of the ideal Gaussian beam is of course 1!

But ideals are certainly not so easy to achieve!

In a real experiment, it is perfect to make the value of M2 infinitely close to 1!

After some guidance from Lu Yu, Group A also quickly realized the possibility of the problem!

"Chief Engineer Lu, do you think you can try it according to our words?"

"Well, let's do another launch experiment."

Lu Yu nodded.

He stood in front of the console and checked all the parameters and connections.

Then, into the microphone, he said: "Group A, prepare to launch!"

"Ready to complete, laser pulse charging is underway!"

"Start launching!"

The group leader pressed a red button and triggered the laser! With the trigger of the button, a dazzling beam of light shoots straight out!

"Good."

Lu Yu looked at the waveform chart displayed on the screen and nodded with satisfaction.

"The launch was successful with a power of 300 MW, a frequency of 300 Hz and a mass factor of 1.01." The team leader reported,

"Okay, write down the values!"

"You guys continue to try two more sets to consolidate the results of the experiment and stabilize the data."

"I'll go to the other groups."

Seeing that the experiment of Group A had been completed, Lu Yu did not continue to stay here for a long time, but shifted his attention to the second and third groups.

The research task here has been basically solved, and it is only necessary to wait until the last step of the system integration test to consider the data of group A.

Soon.

Lu Yu came to the place of the second group.

Unlike Group A's research mission, Group B's research focuses on plasma confinement and emission, which requires the design of a suitable electromagnetic field structure that can effectively envelop and guide charged particle clusters, and control their shape, speed, direction, and stability.

"How?"

Lu Yu didn't say any nonsense and asked directly.

"We're okay here."

"After many simulations and optimizations, we finally designed a tokamak-type electromagnetic field structure based on a ring superconducting magnet, which can not only generate a stable magnetic field with a strength of several Teslas, but also confine heavy hydrogen plasma in a ring-shaped space, and adjust its size and shape by changing the current!"

The leader of Group B introduced Lu Yu with an excited face.

"We also use some high-efficiency and high-capacity electromagnetic devices and controllers, such as superconducting magnets and ultra-high-frequency electromagnetic beam generators, to enhance and control the characteristics of electromagnetic fields!"

"From the current experimental effect, the improvement effect of our research work can be seen with the naked eye! Next, change the speed and direction of the plasma by emitting an ultra-high-frequency electromagnetic beam!

"Oh, not bad!"

Listening to it, Lu Yu's eyes also showed a look of satisfaction!

Sure enough, their exoskeleton equipment research center is a gathering place for talents, and the masters are like clouds! Sometimes, he doesn't need to intervene at all, and he can solve a lot of problems!
