Chapter 516
In the face of these professors’ doubts, Lu Yu has always maintained a calm in his heart, without the slightest angry expression, for him, this kind of questioning is not the first time, he has long been accustomed to it.
After all, it is indeed difficult for a normal person to believe that he really has the ability to solve these problems.
“Professors, I know your biggest question is about the field of resonance absorption.”
“For plasma laser equipment, resonance absorption is indeed a problem that must be solved, if there is no way to curb resonance absorption to the greatest extent.”
“The impact and damage will be terrible. At present, it is true that few technologies can completely solve this problem, but this does not mean that we cannot reduce our losses by suppressing resonance absorption. ”
The idea that Professor Wang just came up with is indeed very open-minded, but I think there are better ideas.”
Lu Yu said slowly.
Hearing Lu Yu’s words, Professor Wang on the side also began to think deeply, guessing what the better method that Lu Yu said in his mouth was?
Others may not believe that Lu Yu has a better way to solve the problem of resonance absorption, but he has known Lu Yu’s identity for a long time, and he deeply understands the problem of resonance absorption, and in the problem solved by Lu Yu… I’m afraid it won’t be ranked at all!
“Say, let’s listen.”
Several professors glanced at Professor Wang next to him with joking eyes, as if to say: “You student is too ignorant of the height of the sky, how can you open your mouth to say such big things?”
But Professor Wang on the side didn’t say anything.
He just sighed deeply in his heart for these old friends, these old guys were afraid that they would be slapped in the face soon….
“I’m sorry.”
“I need a lot of space to say this, so…” Lu
Yu slowly picked up the blackboard to wipe, and then wiped all the content written on the whiteboard before, leaving only a blank whiteboard: “I may have to borrow some tools present.” ”
It’s okay.”
A professor nodded.
Seeing that Lu Yu erased all the formulas and terms he had written down on the whiteboard earlier, although there was a touch of displeasure in his heart, it was still not shown on his face, in the final analysis, he was also curious about what kind of opinion Lu Yu could put forward on the problem of resonance absorption.
Under normal circumstances, it is basically impractical for a graduate student to solve the problem of resonance absorption.
This is true even for graduate students at the National People’s University.
The reason why they were looking forward was also to see if this little guy, who was a disciple of Professor Wang, could come up with some more interesting insights, even if this insight could not be applied in practice.
“Okay, then I’ll get started.”
The corners of Lu Yu’s mouth slowly curved, and then began to explain to everyone.
“Resonance absorption, that is, electrons or ions in the plasma resonate with the frequency of electromagnetic waves under the action of applied electromagnetic waves to produce a strong absorption phenomenon.”
“Plasma resonance absorption will affect the heating, diagnosis and control of plasma, so solving the problem of plasma resonance absorption is of great significance…”
“The scheme proposed by Professor Wang just now is to solve the problem of resonance absorption by changing the laser parameters, this scheme is indeed highly feasible and practical, and if it can be implemented in practice, it can indeed solve the problems caused by resonance absorption to a certain extent.”
Lu Yu first started with the conceptual explanation.
However, for Lu Yu’s speech at this stage, the professors present only raised their eyebrows.
Although these terms sound lofty, they are ultimately just the basic principles of resonance absorption. Not to mention Professor Wang’s disciple, any graduate student who has learned well can say it.
The real difficulty is not what resonance absorption is, but how to solve the problems caused by resonance absorption.
Sure enough….
Lu Yu changed his tone and continued.
“Professor Wang just proposed a solution to resonance absorption by changing the laser parameters, although there is no big problem from the perspective of feasibility, but there are many details that can be further improved.”
“Changing the laser parameters means that the stability of the laser source will be changed to a certain extent.”
“It will affect the stability and quality of the laser, which may lead to uneven laser output or noise, and once there is a problem of uneven laser output, it will affect the heating effect of the laser, which may lead to insufficient or too high plasma temperature!”
“If it’s for ordinary plasma equipment. The issue of temperature is really not that important. If the temperature is too high, adjust it immediately.
“Whether it’s a temperature problem or a laser output problem, any error at any point can’t be used!”
“If there is an error, it can turn the whole experiment upside down!”
As soon as these words came out, the expressions of the professors present changed slightly:
“Do you mean that after changing the laser source parameters, once the laser has an uneven output, it may even make the entire experiment fail directly?”
“This is a bit of an alarmist.”
“Even if there is a temperature problem, it will not have such serious consequences! What’s more, changing the laser parameters directly leads to the problem of uneven laser output, and the possibility of generating it can be said to be minimal! This alone rejects Professor Wang’s proposal: Inadequate.
“Yes, this student, your ideas are too bookish and idealistic.”
“There is a possibility of error at any time, and we cannot veto the entire experimental plan because of a little error.”
Another professor commented the same.
He thinks Lu Yu is still a little too young.
In fact, similar problems have arisen among some young people.
Many young scholars who have just entered the industry, because of the problem of insufficient experience, all programs want to pursue a perfection and standardization! But the problem is that many projects simply cannot be perfect.
It is enough to control the incidence of accidents within a reasonable range!
“Just being a laser source problem is certainly not enough to veto the whole scheme.”
In response to the professors’ doubts, Lu Yu only smiled slightly and further explained:
“In fact, I have no intention of denying Professor Wang’s idea at all. The success rate of this idea is very high, and I just think that there are still some small things that can be improved.
“Also, in addition to the problem of the laser source.”
“Changing the laser pulse width will affect the energy density of the laser, which may lead to uneven plasma density or shock waves, while changing the laser polarization will affect the way the laser is coupled to the plasma, and may also cause the plasma current to be unstable or produce a mode that is not conducive to control…”
“All I want to do is solve these problems.”
As soon as the words landed, the expressions of the professors present changed instantly.
Even Professor Wang next to him flashed an inexplicable look on his face:
“Laser polarization, plasma coupling method…”
“This is true, if you change the laser parameters according to my method, there is really no way to reduce the accident rate in these aspects.”
It may even lead to a subversion of the entire experiment… Although the possibility is not high, it does exist.
He rubbed his temples, and the look in his eyes that looked at Lu Yu suddenly became more admiring.
Although he had long known that Lu Yu’s ability surpassed many people, there was a big gap after all by witnessing and listening to the hearsay!
Although he knew that Lu Yu was a decision-maker of a major project, he still lacked a correct understanding of the ability that Lu Yu showed from time to time!
But today, listening to Lu Yu’s words in the conference room, he said where the shortcomings of the plan he proposed appeared, and Professor Wang finally understood the gap between the two people’s abilities!
“Classmate
, the question you raised, it does exist.”
The expressions of Professor Zhong in the conference room could no longer maintain their initial calmness, at first they just wanted to hear if Lu Yu had any unique opinions.
But with Lu Yu’s words landed.
But they are aware of these raised problems, as if they really exist!
The problem of light being a plasma temperature may not be so important, but coupled with the density of laser energy and the shock wave that laser polarization may generate, they also realized that Lu Yu’s learning time was probably far beyond their initial imagination!
If these problems have been verified after repeated experiments, it would not be so surprising.
But based on Professor Wang’s words, he speculated that a solution might be troublesome.
That’s scary!
According to Lu Yu, changing laser parameters is indeed not a general and optimized solution, but also needs to be selected and adjusted according to specific application scenarios and goals.
“That… What is the better solution you just said?
A professor couldn’t help but ask.
“Well, if you want to avoid these problems and solve the trouble of resonance absorption, you can only start from the root.”
“If you choose to continue to solve the resonance absorption by changing the laser parameters, these problems are almost unavoidable, so if you want to avoid these problems, you can only find another place to start and solve the trouble caused by resonance absorption in another way.”
“My idea is simple.”
Lu Yu began to draw on the whiteboard.
“I think another way to solve plasma resonance absorption is to change plasma parameters such as density, temperature, magnetic field, shape, etc., so that it does not match or move away from the frequency of the laser.”
“If you can make the frequency of the plasma mismatch or move away from the laser, you can reduce the possibility and intensity of resonance absorption!”
“Although this method also cannot completely solve the problem of resonance absorption.”
“But it is more flexible and efficient, and can be adjusted with multiple plasma sources and control devices, as opposed to changing the laser source.” It’s much more suitable, and…” Lu
Yu glanced at Professor Wang next to him and began to explain in detail the possible benefits of the new plan!
“By itself, it enables precise and dynamic control, avoiding the loss and complexity of laser parameterization equipment. At the same time, it can also adapt to different types and frequencies of lasers, avoiding the limitations and costs caused by laser parameter adjustment equipment…” With
the detailed release of the specific plan, the professors present could not bear it instantly!
“This:
“In this case, this plan is really feasible!”
“It can use the characteristics and advantages of the plasma itself to avoid the interference and influence caused by laser parameter adjustment equipment.” Without a doubt, this is definitely a huge reduction in possible problem failures!
“Yes, we have discussed similar solutions before, but there is no way to go further for technical reasons.” But if you follow this student’s plan, the troubles that may have been encountered in terms of technology seem to have disappeared! At
this moment, these professors’ eyes looked at Lu Yu, and finally completely changed!
If at the beginning, they looked at Lu Yu’s eyes, and they were a little contemptuous.
So at this moment, just the word “shock” is enough to describe their mood!
It’s not hard to figure out the trouble.
Saying where the specific trouble is, although it is somewhat difficult, is not so difficult.
Solves troubles… That’s not the same difficulty!
Under their noses, the Soviet army Luyu not only easily found out the trouble, said where the trouble appeared, but also solved the trouble in just two words?
This ability… No need to say more!
“Is there any additional flaw in that by changing the plasma parameters to reduce the trouble of resonant absorption?”
A professor asked.
“Of course there are flaws.”
“There is hardly any solution in the world that is perfect. Changing plasma parameters also has some disadvantages.
Lu Yu also did not hide anything, and said frankly:
“Changing the plasma parameters means that more and more complex plasma sources and control devices are required, which increases the complexity and cost of the system.” In addition, it requires more and more accurate plasma diagnostic technology, which makes the measurement and feedback of the system more difficult.”
“These are all problems in the objective sense of this scheme.”
“However, I believe that for our current scientific research capabilities of the Dragon Kingdom, these costs are not impossible to pay.”
“Truly, if the problem is only complexity and cost, it is indeed much easier than the technical problem.”
The professor who asked at the beginning nodded in agreement.
The cost problem, to put it bluntly, is burning money.
As long as there is money and money is invested in it, it can produce scientific research results and contribution, so what is the problem with spending a little more money?
But if it’s a technical problem… That’s not about money!
