Into Unscientific Chapter 533

   Right now.

  In the ward.

   Facing Xu Yun who was lying on the bed, Lao Guo's inner surprise was already beyond words.

   Under shock.

  His mouth was even wider than Xu Yun's, and his whole figure seemed to be frozen.

   Here we go.

  He finally understood why Xu Yun asked them "Dare you dare?"

   It turned out that his goal was nothing else but

  The 2.5MeV proton electrostatic accelerator at the Institute of High Energy!

   Or to be precise.

   is 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:

  Transport the charge of the corona discharge of the electrospray needle to an insulated hollow metal electrode through the power transmission belt, so that it can be charged to a high voltage to accelerate the charged particles. It can be regarded as a relatively early particle acceleration device.

  The main structure of an electrostatic accelerator is generally based on the high-voltage generator as the core, and then 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 and relatively moderate energy dispersion, the analyzer of the electrostatic accelerator must have the following properties:

  Arbitrarily receive the electron flow data of angle θ.

  Can perform quadrature demodulation skew processing—because the breakdown voltage of the negative polarity high-voltage electrode is higher than that of the positive polarity.

  Can complete periodic frequency conversion in the process of fixed to non-fixed component amplitude.

   That is, 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 with an energy level exceeding 1MeV in China.

   Actually.

  Even if the 1MeV limit is set aside, the value of the proton electrostatic accelerator that Xu Yun is eyeing will not decrease a bit:

  Because up to now, there are only two proton electrostatic accelerators in China.

  One 700KeV.

   One 2.5MeV.

   The result was unexpected.

  Xu Yun actually set his mind on this important weapon of the country?

  Compared to Lao Guo who was so surprised that he might have a heart attack at any time.

  Xu Yun on the bed looked very calm.

   After all, as a descendant, he certainly knows the importance of this electrostatic accelerator.

  Naturally, I had already expected Lao Guo's reaction.

Of course.

  Seeing this, some students may express surprise:

   Not right.

  Why would Xu Yun, a Cambridge graduate who sneaked back to China, know about the equipment just produced in China?

Unfortunately.

  The 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 definition of the so-called 'just produced'.

   As for why Xu Yun was able to know about these two devices

  That's because from the purchase of parts to the assembly, the rabbits didn't hide at all, and they advertised their progress with great fanfare from beginning to end.

  For example, Dahe Commune, the predecessor of Dahe Township, Qixingguan District, BJ City, in the same province as the classmate who raised this question, put up big-character posters for three months when the accelerator landed.

  At the same time, many foreign newspapers such as "The Times" and "Observer" have also reported the whole incident in detail.

  Feynman, who was far away at Caltech at the time, was invited to contribute, discussing what the rabbits could discover with this device.

  So even if Xu Yun is really an international student of this era, there is no problem knowing that the rabbits have electrostatic accelerators.

  Another interesting thing is.

   During the process of developing the electrostatic accelerator, the rabbits also encountered a noble person to help.

   This happened in 1946, the first year after the victory of the Anti-Japanese War.

  At that time, Mr. Zhao Zhongyao went across the sea to visit the atomic bomb test of Bikini Island, and at the same time shouldered another important task:

   Buy an electrostatic proton accelerator and come back to start Huaxia's own nuclear physics career.

Of course.

  At that time, a logistics leader in China was still in charge, so this matter itself had nothing to do with the rabbits.

  The nuclear business of the rabbits did not start until after the founding of the country.

  At that time, Sa Bendong and Wu Youxun managed to raise a sum of US$50,000 for Mr. Zhao Zhongyao, which was a huge sum at the time.

   But the word "big money" is only aimed at ordinary consumption, and it is insignificant in the field of scientific research.

  The cheapest, complete set of 2.5Mev electrostatic accelerator at that time cost 400,000 U.S. dollars, eight times higher than Mr. Zhao's budget.

  So Mr. Zhao, who had been tinkering with Great Wall pencils, thought of a way:

   Only purchase parts that are difficult to buy in China and a small amount of other nuclear physics experiment equipment, and design and assemble an accelerator by myself after returning to China.

  Anyway, it's just as long as you have this thing in your hand.

  For this reason, Mr. Zhao spent more than two years in several accelerators and cosmic ray laboratories such as the Massachusetts Institute of Technology, the Carnegie Institute of Magnetic Research in Washington, and so on.

   While purchasing and processing equipment, he further learned new technologies.

   He even volunteered 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:

  Clear foreign scientists from nuclear physics laboratories under its jurisdiction.

   Fortunately, Mr. Zhao has a wide network of contacts across the sea. Even in the most difficult period, he has received help from many friends.

   Among the people who supported Mr. Zhao the most, one was the head of the experimental department of the MIT Radiology Laboratory.

  He pioneered X-rays to treat cancer, researched radar during World War II, and won the Distinguished Service Medal across the sea.

   In addition, together with van der Graaf, he invented the practical proton electrostatic accelerator, which is a very high achievement.

  After learning of Mr. Zhao's difficulties, this enthusiastic scientist immediately extended a helping hand.

   Not only opened the entire laboratory to Mr. Zhao, allowing him to copy the materials at will.

   Even listed an old proton electrostatic accelerator that was about to be scrapped in the unit as a "waste product", and gave it to Mr. Zhao as a set.

  After the establishment of New China.

  Ms. Zhao went through untold hardships, broke through the obstacles across the sea, and transported this batch of equipment back to China.

  Finally, relying on the main components of the old electrostatic accelerator at MIT, 700KeV and 2.5MeV electrostatic accelerators were successively manufactured.

   This incident is not a fabrication of escorting Radium, but the real story of Mr. Zhao, which is recorded on the official website of Huaxia Institute of Nuclear Engineering.

   And what's so interesting about this whole thing?

  As for the head of the MIT laboratory who gave Mr. Zhao the old electrostatic accelerator.

  His name is

  John GTrump.

   That's right.

   is the uncle who knows the king now.

   It's not over yet.

  In the 1980s, J.G. also helped the 401 Research Institute buy a tandem electrostatic accelerator across the sea

  This incident was recorded by Mr. Zhao in the memoir "My Memories", which can be seen in "Selected Papers of Zhao Zhongyao".

  Tears.JPG.

  The line of sight returns to reality.

all in all.

  At present, only the electrostatic analysis module of the electrostatic accelerator can meet Xu Yun's requirements in terms of process.

  At the same time, the module on the 700KeV V1 accelerator cannot operate when the angle is lower than 20°, and cannot meet the requirement of arbitrary receiving angle θ.

   So in desperation.

  Xu Yun could only focus on the 2.5MeV accelerator.

Of course.

  A large part of the reason why Xu Yun dared to make this choice is also because he is familiar with the historical trajectory.

  He knows one thing very well:

   In about two years, Mr. Xie Jialin will lead a team to develop the first 30MeV electron linear accelerator in China.

  Although I don't know how far the accelerator's research is now—after all, this matter has not been deciphered in detail in 2023, but judging from the time, it should also enter the final stage.

   That is to say, from the perspective of fault tolerance, there is a relatively complete bottom line, so that all studs will not enter.

  Besides, the electrostatic analysis module can be reinstalled after being removed, although this kind of thing may be a bit NTR for the accelerator.

  After Lao Guo guessed Xu Yun's idea.

  Xu Yun stopped wasting words, and just calmly waited for Lao Guo's reply.

   About five or six minutes passed.

  Old Guo couldn't help but sighed in disappointment, shook his head, looked at Xu Yun, and sighed:

   "Comrade Han Li, you really gave me a big problem"

   Say it.

  Old 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 problems, so I can't give you a specific answer at the moment."

   "So let's do this, I'll go to the factory leader now to see what the management thinks."

   "If the leader agrees, everyone will be happy, if not."

  Xu Yun raised his head and glanced at Lao Guo, and chose to press the wave:

   "Guo Gong, if the leader disagrees, then I'm afraid there's nothing I can do."

   "I'm not a person in the future who knows everything. The only solution I know is weather Doppler radar."

  Old Guo Moran nodded.

   Then soon.

  Old Guo put away his things one by one, and left the ward quickly with his briefcase in hand.

   Not long after Lao Guo left.

  On both sides of the corridor of the intensive care unit, two more capable soldiers on duty quietly appeared

  The staff hospital is very close to the main factory office, and the straight-line distance is only a few hundred meters shorter.

  That's why Lao Guo brought canned beef to visit Xu Yun after the meeting.

   Come quickly, naturally it won't take long to go back.

  After leaving the hospital for more than ten minutes.

  Old Guo then returned to the factory office.

  There are five steps 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 on the steps, saying goodbye to a comrade from another project team.

  So he walked over naturally, and greeted Zhou Cai:

   "Assistant Zhou, are you busy?"

   Zhou Cai turned his head subconsciously, and was taken aback when he saw Lao Guo:

   "Guo Gong? Are you doing a good job?"

  Old Guo nodded to him, then raised his chin toward the building, and asked:

   "Well, the matter has been dealt with. Are those people still there?"

  Zhou Cai knew that Lao Guo was asking many leaders who participated in the voting before, so Dang even shook his head:

   "Guo Gong, everyone has important matters to attend to, so after the meeting, almost everyone left."

  Old Guo's complexion didn't change much, after all, few people were optimistic about Xu Yun's proposal before going to Xu Yun.

  Besides, even if there are results to be produced, it may not be necessary for how long to communicate.

  The big guys who participated in the meeting were at least the heads of each branch factory. Naturally, it is impossible to wait here for this matter. It is normal to leave the factory office after the meeting is over.

   So Lao Guo quickly changed the way of asking:

   "Then Assistant Zhou, is Director Li there?"

   "Oh, the factory manager is here."

  Zhou Cai nodded quickly and said:

   "In addition, Director Zhang, Lu Gong, and Vice President Cheng have not left yet, and they are holding a small meeting."

  Hearing that General Excalibur 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 seeing Lao Guo's performance now, Zhou Cai had a guess in his heart:

   Murphy

   That half cooked really gave a solution to the weather data?

  Think here.

  Zhou Cai didn't dare to neglect, and quickly led Lao Guo into the factory building.

  The "small meeting" of Li Jue and others did not choose the original meeting room, but changed to a small private room on the second floor.

   After going upstairs.

  Zhou Cai led Lao Guo out of the house, and knocked on the door:

   "Director, Mr. Guo is back."

   I don't know if it's an illusion.

  Hearing Zhou Cai's words, Lao Guo felt that the room, which had no sound at first, seemed to be faintly quiet for a moment.

   After a while.

   Li Jue's voice came out:

   "Come in, please."

   Seeing this, Lao Guo thanked Zhou Cai, and immediately opened the door and entered.

  The area of ​​this room is only about 20 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 middle of the room, there is an Eight Immortals table, on which there are some peanuts and a few packs of unpacked bear biscuits.

  Compared to the previous meeting, there were only five or six high-level people chatting in the room at this time, but the density of the smoke was not inferior to the previous round.

   After Lao Guo entered the house.

  Li Jue took the initiative to pull a chair to signal Lao Guo to sit down, and said with a smile:

   "Old Guo, why are you so quick?"

   As a result, the words were not finished.

  Li Jue noticed Lao Guo's extremely solemn expression.

  So his movements suddenly stopped, and he suddenly realized something in his heart, and his tone became serious from joking:

   "Old Guo, have you gained something?"

  Old Guo nodded vigorously, took out the notebook from his body, and shook a corner at them:

   "A very special harvest, the details are very complicated."

   Li Jue raised his eyebrows when he heard the words, smoked a dry cigarette from the table and handed it to Lao Guo, saying:

   "Old 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.”

  Old Guo let out a coquettish remark with a strong style of the early Internet of later generations, and then he flattened the notebook on the table and said to everyone:

   "Okay, let's stop talking nonsense, let me introduce the specific principles of the plan first."

   "Han Li proposed a solution called meteorological Doppler radar. In theory, I personally feel that it is feasible, that is, relying on the Doppler effect."

   Lao Guo gestured while talking, and quickly explained the whole principle.

  He chose to take the simplest part, and focused on the last part to answer in detail.

  General Excalibur and Li Jue are both soldiers who don't know much about scientific research theory. They only care about smoking during the whole process, and they don't say a word during the whole process.

  Listen to the Book of Heaven.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 rhythm from a purely theoretical perspective.

   After all, Chinese students studying abroad these days, especially science students, can be said to be the omnipotent party, knowing a little bit about all aspects.

   So listen, listen.

  The expressions of several people became more serious.

   At the end.

  Lu Guangda even took out a pen and paper and checked the calculation on the table.

   "If the frequency band of precipitation particles in the atmosphere is in Ka, directly preset an eigenfunction is ∫L(Ψ, Ψ, 1ctΨ)d3x"

   "Here is an integral. Speaking of Meng Xiong, do you still remember the main absorption bands of water vapor?"

   "1.35cm, which is 22.235Ghz."

   "Okay, so the one-way attenuation is 0.27x0.679"

   After a while.

  Lu Guangda's pen tip on the paper suddenly paused.

  I saw him, Peng Mengxiong and Cheng Kaijia look at each other, and then the three of them looked at Lao Guo at the same time:

   "You Lai, this idea is to use orthogonal demodulation and oblique processing?"

  Old Guo nodded, not surprised that Lu Guangda could make this judgment, and asked at the same time:

   "Yes, do you think it is feasible?"

   "does seem to work"

  Lu Guangda's eyes flickered a few times, and there was a hint of hesitation in his tone:

   "But the sieving link may be difficult to achieve, right? One condition is an arbitrary angle, and the other must satisfy periodic polarization."

   "At least in my opinion, there should be no sub-sieve-adapted modules produced in China"

   "No!"

   Hearing Lu Guangda's words.

   Before Lao Guo could make a sound, Peng Mengxiong interrupted him suddenly:

   "Guangda, you are wrong."

   "If we calculate the echo coefficient and sub-period frequency difference, there should be an analysis module in China that can achieve this level of data support."

  A question mark appeared in Lu Guangda's eyes:

   "Which mod?"

  Peng Mengxiong was silent for a moment, then pointed at Lao Guo:

   "It's the 2.5MeV proton electrostatic accelerator at Youlai Institute of High Energy. The electrostatic analysis module of that equipment should be fine."

  Peng Mengxiong finished speaking.

  Suddenly there was a brief silence at the scene.

  Lu Guangda and Cheng Kaijia seemed to have been pressed the pause button, and the expressions on their faces froze instantly.

   After a few seconds.

  Boom!

  Cheng Kaijia slammed the table and shouted angrily:

   "Electrostatic accelerator? How can this work? I disagree! This device must not be dismantled!"

   "Spicy chicken, if I had known that Han Li was going to dismantle the electrostatic accelerator, I wouldn't be able to vote for it!"

  Cheng Kaijia is in charge of security affairs in the base. He is a relatively rare talent with dual training in "science" and "army". He has always been quite irritable.

  At the same time, he is also the beloved disciple of Mr. Zhao Zhongyao, and he knows how much effort his teacher has put into this accelerator.

   Therefore, whether it is reason or emotion, he is not allowed to agree to Xu Yun's plan at this time.

   "Kaijia, don't be in a hurry."

  Looking at Cheng Kaijia who was panting heavily, General Excalibur, who had been silent all this time, couldn't help pressing down a few times, and said to him:

   "What Comrade Youlai relayed is just a plan. Whether it can be implemented is another matter. There is no need to get angry now."

  “What we have to do now is not to be angry, let alone look at the problem with colored glasses, but to discuss objectively whether it is feasible.”

   "Kai Jia, I'm not talking about you, you really need to change your temper."

   Say it.

  General Excalibur 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 didn't give an answer immediately when he heard the words, but continued to count with his head down.

   After ten minutes.

  Lu Guangda put down his pen, looked up at Cheng Kaijia, stroked his chin and said:

   "Director Zhang, I feel that this plan has a certain success rate—well, at least in theory."

   Cheng Kaijia frowned immediately when he heard the words:

   "Guangda, you"

   But before he spoke, Lu Guangda seemed to have predicted something, and handed the calculation paper in front of him:

   "Old Cheng, this is the deduction I made from the one-dimensional state. The frame is all the parameters of the electrostatic analysis module of the electrostatic accelerator. Take a look."

  Cheng Kaijia was stuck in the second half of his words. He first glanced at Lu Guangda a few times, and then took the paper to read it.

A few minutes later.

  Cheng Kaijia silently put the paper back on the table, with some hesitation evident in his eyes.

  However, perhaps subconsciously, he was extremely resistant 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, but their attitudes were not particularly firm.

  See this scenario.

  Li Jue couldn't help but look at General Excalibur. Fortunately, both of them are veteran generals who have experienced battles. General Excalibur quickly made a choice:

   "Old Li, since that's the case."

   "Contact my family."

Note:

  Some students said that the reason I wrote about the female classmate in the chapter was to avoid opening the emotional line, but the problem is that this is true. I even visited her grave this year.

  Double monthly pass at the end of the month, please vote! !
