Facing Xu Yun lying on the bed, Lao Guo's inner surprise could not be expressed in words.
In shock.
His mouth was even wider than Xu Yun's, and his whole figure seemed to be frozen.
At this point.
He finally understood why Xu Yun asked them "dare you dare".
It turns out that his goal is nothing else but...
The 2.5MeV proton electrostatic accelerator of the Institute of High Energy!
Or to be more precise.
It's the electrostatic analysis module on the proton electrostatic accelerator.
After all, only the electrostatic analysis module used to analyze the impact state of particles can fully meet the requirements designed by Xu Yun.
The so-called electrostatic accelerator refers to a particle accelerator that uses an electrostatic high-voltage generator as a high-voltage power supply.
Its principle is actually very simple:
The charge from the corona discharge of the spray needle is transported to an insulated hollow metal electrode through a power transmission belt, where it is charged to a high voltage to accelerate charged particles. It is considered an early particle acceleration device.
The main structure of an electrostatic accelerator generally has a high-voltage generator as the core, and is equipped with multiple modules such as ion source, accelerating tube, analyzer, voltage stabilization and control system.
In order to ensure the analysis accuracy of the target beam current and the relatively moderate energy dispersion, the analyzer of the electrostatic accelerator must have the following attributes:
Electron flow data at any angle of θ can be received.
Quadrature demodulation slope processing can be performed - because the breakdown voltage of the negative polarity high voltage electrode is higher than that of the positive polarity.
Complete periodic frequency conversion can be performed in the process of fixed and non-fixed component amplitudes.
That is to say, in terms of attributes.
The electrostatic analysis module of the electrostatic accelerator is indeed a perfect fit for Xu Yun’s plan.
but.....
That thing is the only proton electrostatic accelerator in China with an energy level exceeding 1MeV...
Actually.
Even if the 1MeV limit is set aside, the value of the proton electrostatic accelerator that Xu Yun is eyeing will not be reduced at all:
Because as of now, there are only two proton electrostatic accelerators in China.
One 700KeV.
One 2.5MeV.
The result was unexpected...
Xu Yun actually set his sights on such an important weapon of the country?
Compared to Lao Guo, who looked so surprised that he might have a heart attack at any time.
Xu Yun looked very calm on the bed.
After all, as a descendant, he certainly knew the importance of this electrostatic accelerator.
Naturally, I had already anticipated Lao Guo's reaction.
Of course.
Seeing this, some students may be surprised:
That's not right.
Why would Xu Yun, a Cambridge graduate who secretly returned to China, know about the equipment just produced in China?
Unfortunately.
This question itself is very wrong.
The first 700KeV electrostatic accelerator model in China is called V1, which was launched 6 years ago, and the 2.5MeV one was launched 3 years ago.
No matter which device it is, it obviously does not meet the so-called "newly produced" definition.
As for why Xu Yun knew these two devices...
That's because from the purchase of parts to the assembly, the rabbits didn't hide anything at all, and they publicized the progress in a big way from beginning to end.
For example, the predecessor of Dahe Commune in Dahe Township, Qixingguan District, BJ City, which is in the same province as the classmate who raised this question, posted big-character posters for three months when the accelerator was launched.
At the same time, many foreign newspapers such as The Times and The Observer have also reported the entire incident in detail.
Feynman, who was far away at Caltech at the time, was invited to contribute a paper to discuss what rabbits could discover with this device.
So even if Xu Yun is really an international student of this era, there will be no problem knowing that the rabbits have electrostatic accelerators.
Another interesting thing is.
In the process of developing the electrostatic accelerator, the rabbits once met a noble person for help.
This happened in 1946, the first year after the victory of the Anti-Japanese War.
At that time, Mr. Zhao Zhongyao went to the other side of the sea to visit the Bikini Island atomic bomb explosion test, and at the same time shouldered another important task:
Buy an electrostatic proton accelerator and start China's own nuclear physics business.
Of course.
At that time, a certain logistics leader in China was still calling the shots, so the matter itself had nothing to do with the rabbits.
The rabbits' nuclear career still had to start after the founding of the People's Republic of China.
At that time, Mr. Sabendong and Mr. Wu Youxun managed to raise US$50,000 for Mr. Zhao Zhongyao, which was a huge sum of money at the time.
But the word "huge sums of money" only refers to ordinary consumption, and is insignificant in the field of scientific research.
The cheapest one at that time, a complete set of 2.5Mev electrostatic accelerator, cost US$400,000, which was a full eight times higher than Mr. Zhao’s budget.
So Mr. Zhao, who had tinkered with Great Wall pencils, thought of a way:
I only purchased parts that were difficult to buy in China and a small amount of other nuclear physics experimental equipment, and designed and assembled an accelerator myself after returning to China.
Anyway, this thing only needs hands.
For this reason, Mr. Zhao spent more than two years in several accelerators, such as the Massachusetts Institute of Technology, the Carnegie Institute of Magnetism in Washington, and the cosmic ray laboratory.
While purchasing and processing equipment, he further learned new technologies.
He even worked voluntarily for several laboratories in exchange for learning and consulting opportunities.
The result was unexpected.
As the domestic situation gradually tilted toward the rabbit, the Atomic Energy Commission across the sea suddenly issued an order:
Eliminate foreign scientists from nuclear physics laboratories under its jurisdiction.
Fortunately, Mr. Zhao has a wide network of contacts across the sea, and even in the most difficult times, he has received help from many friends.
One of the people who supports Teacher Zhao the most is the head of the experimental department of the MIT Radiation Laboratory.
He pioneered X-ray treatments for cancer, worked on radar during World War II, and received the Distinguished Service Medal across the sea.
In addition, he and Van de Graaf invented a practical proton electrostatic accelerator, which was a very high achievement.
After this enthusiastic scientist learned about Teacher Zhao's difficulties, he immediately extended a helping hand.
Not only did they open the entire laboratory to Teacher Zhao, allowing him to copy information at will.
He even classified an old proton electrostatic accelerator that was about to be scrapped by his unit as "scrap" with a stroke of a pen and gave the complete set to Teacher Zhao.
After the founding of New China.
Teacher Zhao went through untold hardships and overcame many obstacles on the other side of the sea to transport this batch of equipment back to China.
In the end, 700KeV and 2.5MeV electrostatic accelerators were manufactured using the main components of the old electrostatic accelerator at MIT.
This incident is not a fabrication of escorting radium, but a real incident of Mr. Zhao, which is recorded on the official website of the Huaxia Nuclear Institute.
And what’s the interesting part about the whole thing?
As for the head of the MIT laboratory who gave Mr. Zhao his old electrostatic accelerator.
His name is...
John G Trump.
That's right.
He is the current uncle who understands the king.
This isn't over yet.
In the 1980s, J.G. also helped the 401 Research Institute purchase a tandem electrostatic accelerator from across the sea...
This incident was recorded in Mr. Zhao's memoir "My Memories" and can be seen in "Selected Essays of Zhao Zhongyao".
Tears.JPG.
His eyes returned to reality.
all in all.
Currently, the only thing that can meet Xu Yun's requirements in terms of process is the electrostatic analysis module of the electrostatic accelerator.
At the same time, the module on the 700KeV V1 accelerator cannot operate below 20° and cannot meet the requirement of receiving any θ angle.
So in desperation.
Xu Yun could only put his mind to the 2.5MeV accelerator.
Of course.
A large part of the reason why Xu Yun dared to make this choice was that he was familiar with the historical trajectory.
He knows one thing very well:
In about two years, Mr. Xie Jialin will lead his team to develop the first 30MeV electron linear accelerator in China.
Although I don’t know the specific extent of the research on that accelerator now - after all, this matter has not been declassified in detail in 2023, but judging from the time, it should have entered the final stage.
That is to say, from a fault-tolerance perspective, there is a relatively good margin, so that everyone will not be able to get into it.
Moreover, the electrostatic analysis module can be put back after being removed, although this may be a bit NTR for the accelerator...
After Lao Guo guessed what Xu Yun was thinking.
Xu Yun stopped talking and just waited calmly for Lao Guo's reply.
"...."
About five or six minutes passed.
Lao Guo couldn't help but sigh with sadness, shook his head, looked at Xu Yun, and sighed:
"Comrade Han Li, you really gave me a big problem..."
Say it.
Lao Guo looked at the notebook full of writing again, snapped it shut, and said to Xu Yun:
"Comrade Han Li, the dismantling of the electrostatic accelerator involves many issues, so I can't give you a specific reply at the moment."
"So let's do it. I'm going to go find the leaders of the factory now and see what the management thinks."
"If the leader agrees, everyone will be happy, if not..."
Xu Yun looked up at Lao Guo and chose to put pressure on him:
"Guo Gong, if the leader doesn't agree, then I'm afraid there's nothing I can do to help."
"I'm not a person from the future who knows everything. The only solution I know about is weather Doppler radar."
Lao Guo nodded silently.
Then very quickly.
Lao Guo collected his belongings one by one and quickly left the ward with his briefcase.
Shortly after Lao Guo left.
On both sides of the corridor of the special care ward, two capable soldiers on duty quietly appeared...
.........
The staff hospital is very close to the main factory office, and the straight-line distance is only about a few hundred meters.
That's why Lao Guo came to visit Xu Yun with canned beef after the meeting.
If you come quickly, it won't take long to go back.
More than ten minutes after leaving the hospital.
Lao Guo then returned to the main factory office.
There is a five-level staircase at the entrance of the factory office. When Lao Guo arrived at the factory office, he happened to see Li Jue's assistant Zhou Cai saying goodbye to a comrade from other project teams on the steps.
So he walked over naturally and greeted Zhou Cai:
"Assistant Zhou, are you busy?"
Zhou Cai subconsciously turned his head and was stunned when he saw Lao Guo:
"Guo Gong? Are you... doing something good?"
Lao Guo nodded towards him, then moved his chin towards the building and asked:
"Well, now that the matter has been settled, are the people inside still there?"
Zhou Cai knew that Lao Guo was asking about the many leaders who had participated in the vote, so he immediately shook his head:
"Gong Guo, everyone has important matters to attend to, so almost everyone left after the meeting..."
Lao Guo's expression didn't change much. After all, before going to Xu Yun, few people were optimistic about Xu Yun's plan.
Moreover, even if results are produced, communication may not take long.
The big guys attending the meeting are at least the heads of each branch factory. Naturally, they cannot wait here for this matter. It is normal for them to leave the factory office after the meeting.
So Lao Guo quickly changed his question:
"So Assistant Zhou, are Director Li here?"
"Oh, the factory director is here."
Zhou Cai nodded quickly and said:
"In addition, Director Zhang, Engineer Lu, and Vice President Cheng have not left yet. They are having a small meeting."
Hearing that General Shenjian was still here, Lao Guo immediately patted Zhou Cai on the shoulder and said urgently:
"Okay, Assistant Zhou, take me there. I have an emergency to report."
As Li Jue's political assistant, Zhou Cai is responsible for sorting out meeting minutes after various meetings, and is no stranger to many confidential contents.
So now seeing Lao Guo's behavior, Zhou Cai had a guess in his heart:
Could it be...
Does the Medium Rare really provide a solution to weather data?
This chapter is not over, please click on the next page to continue reading! I thought of this.
Zhou Cai did not dare to neglect and quickly led Lao Guo into the factory building.
Li Jue and others' 'small meeting' was not held in the original conference room, but was moved to a small single room on the second floor.
After going upstairs.
Zhou Cai led Lao Guo outside the house and knocked on the door:
"Director, Guo Gong is back."
I don't know if it's an illusion.
After hearing Zhou Cai's words, Lao Guo felt that the room, which had no sound at all, seemed to be quiet for a moment.
After a while.
Li Jue's voice came out:
"Please come in."
Upon seeing this, Lao Guo thanked Zhou Cai and immediately opened the door and entered.
The area of this room is only about twenty square meters. There is a small tea room on the left side. You can see a hot water pipe leading from the boiler room below.
In the center of the room was an Eight Immortals table, with some peanuts and a few unpacked packs of furry bear biscuits placed on it.
Compared to the previous meeting, there were only about five or six people in the upper floors of the room at this time, but the smoke was no less dense than the previous one.
Wait for Lao Guo to enter the house.
Li Jue took the initiative to pull up a chair and motioned for Lao Guo to sit down, and said with a smile:
"Lao Guo, why did you..."
As a result, the words were not finished.
Li Jue noticed Lao Guo's extremely solemn expression.
Then his movements paused, and he suddenly realized something in his heart, and his tone changed from joking to serious:
"Lao Guo, have you gained something?"
Lao Guo nodded vigorously, took out his notebook from his body, held a corner and shook it towards them:
"A very special harvest, the details are very complicated."
Li Jue raised his eyebrows when he heard this, took a dry cigarette from the table and handed it to Lao Guo, saying:
"Lao Guo, it seems that Comrade Han Li gave us a big surprise this time."
"...It may not be a surprise, it may be a shock."
Lao Guo came out with a saucy remark that had a strong early Internet style, then spread his notebook flat on the table and said to everyone:
"Okay, let's stop talking nonsense and let me introduce the specific principles of the plan first."
"Han Li proposed a solution called weather Doppler radar. In theory, I personally think it is feasible, that is, it relies on the Doppler effect..."
Lao Guo quickly explained the entire principle while talking and making gestures.
He chose to go through the simplest part and focused on the last part to answer it in detail.
General Shenjian and Li Jue, both soldiers who didn't know much about scientific research theory, only smoked and said nothing during the whole process.
Tingtianshu.jpg.
But Lu Guangda, Peng Mengxiong and Cheng Kaijia are different.
Although their majors are not directly related to radar research and development, they can still keep up with the pace from a purely theoretical perspective.
After all, Chinese international students these days...especially science students, can be said to be all-rounders, knowing a little bit about everything.
So listen, listen.
The expressions of several people became more solemn.
At the end.
Lu Guangda even took out a pen and paper and started checking the calculations on the table.
"If the frequency band of precipitation particles in the atmosphere is in Ka, a direct preset eigenfunction is ∫L(Ψ,?Ψ,1c?tΨ)d3x..."
"Let's make a point here... Speaking of Meng Xiong, do you still remember what the main absorption band of water vapor is?"
"1.35cm, which is 22.235Ghz."
"Okay, then the one-way attenuation is 0.27x0.679..."
After a while.
Lu Guangda's pen tip on the paper suddenly paused.
He, Peng Mengxiong and Cheng Kaijia looked at each other, and then the three of them looked at Lao Guo at the same time:
"Friends, this idea... is to prepare for orthogonal demodulation and oblique processing?"
Lao Guo nodded, not surprised that Lu Guangdan could make this judgment, and asked at the same time:
"Yes, do you think it's feasible?"
"It seems feasible..."
Lu Guangda's eyes flickered a few times, and there was a trace of hesitation in his tone:
"But the sieving process is probably difficult to achieve, right? One condition is arbitrary angle, and the other condition is periodic polarization..."
"At least in my opinion, there should be no domestically produced modules suitable for screening..."
"wrong!"
Hearing Lu Guangda's words.
Before Lao Guo could say anything, Peng Mengxiong on the side suddenly interrupted him:
"Guangda, you are wrong."
"If we calculate the echo coefficient and sub-period frequency difference according to our calculations, there should be an analysis module in China that can achieve data support of this magnitude."
Lu Guangda couldn't help but have a question mark in his eyes:
"Which module?"
Peng Mengxiong was silent for a moment, then pointed at Lao Guo:
"It's the 2.5MeV proton electrostatic accelerator from their High Energy Institute. The electrostatic analysis module of that equipment should be fine."
"..."
Peng Mengxiong finished speaking.
There was a brief silence at the scene.
Lu Guangda and Cheng Kaijia seemed to have pressed the pause button, and the expressions on their faces instantly froze.
After a few seconds.
Bang!
Cheng Kaijia slammed the table and shouted angrily:
"Electrostatic accelerator? How can this be done? I disagree! This device must not be dismantled!"
"What a jerk! If I had known earlier that Han Li was going to dismantle the electrostatic accelerator, I wouldn't have voted in favor of anything!"
Cheng Kaijia is responsible for security affairs in the base. He is a relatively rare talent with dual majors in "science" and "military". His personality has always been relatively irritable.
At the same time, he is also Mr. Zhao Zhongyao's beloved disciple, and he knows how much effort his teacher has put into this accelerator.
Therefore, neither reason nor emotion allowed him to agree to Xu Yun's plan at this time.
"Open armor, please don't rush."
Looking at the panting Cheng Kaijia, General Shenjian, who had not spoken a word, couldn't help but press his men down a few times and said to him:
"What Comrade Youlai relayed is just a plan. Whether it can be implemented is still a matter of debate. There is no need to get angry now."
This chapter is not over, please click on the next page to continue reading! "What we need to do now is not to be angry, nor to look at the problem through colored glasses, but to objectively discuss whether it is feasible."
"Kai Jia, I'm not telling you, you really should change your temper."
Say it.
General Shenjian turned to look at Lu Guangda and Peng Mengxiong, and asked them:
"Guangda, Mengxiong, what do you think?"
"Director Zhang, please wait a moment."
Lu Guangda did not answer immediately after hearing this, but continued to lower his head and calculate.
About ten minutes passed.
Lu Guangda put down his pen, looked up at Cheng Kaijia, touched his chin and said:
"Director Zhang, I feel that this plan has a certain success rate - well, at least it's not low in theory..."
Cheng Kaijia frowned immediately after hearing this:
"Guangda, you..."
But before he spoke, Lu Guangda seemed to have predicted something and handed the calculation paper to him:
"Lao Cheng, this is the derivation I made from the one-dimensional state. The parameters in the frame are the electrostatic analysis module parameters of the electrostatic accelerator. Take a look."
"...."
The second half of Cheng Kaijia's words was stuck in his mouth. He glanced at Lu Guangda a few times, then took the calculation paper and started reading.
A few minutes later.
Cheng Kaijia silently put the calculation paper back on the table, with some hesitation evident in his eyes.
However, perhaps because of his subconscious resistance to this plan, Cheng Kaijia finally shook his head:
"Old Li, Director Zhang, I still reserve my opinion and firmly disagree with this plan."
Li Jue frowned slightly and looked at Peng Mengxiong again.
Peng Mengxiong pursed his lips and thought for a moment, then shook his head:
"Director, I am not a professional practitioner of radar, and the time for demonstration is relatively limited, so I... abstain."
The four experts present made three choices:
Cheng Kaijia objected.
Peng Mengxiong abstained.
Lu Guangda and Lao Guo supported it, but their attitude was not particularly firm.
See this situation.
Li Jue couldn't help but look at each other with General Shenjian. Fortunately, both of them were experienced generals in the battlefield. General Shenjian quickly made a choice:
"Old Li, in that case..."
"Contact your family."
