Into Unscientific Chapter 624

 “There's something wrong with the blueprint the British guy gave me!”

Xu Yun's words were extremely clear in the empty and quiet operating room at this time, making the already quiet scene fall silent again.

　　The expressions of big bosses such as Wang Ganchang, Lao Guo, Cheng Kaijia, etc. who were expecting the accelerator to be turned on all froze at the same time.

　More than ten seconds have passed.

Zhao Zhongyao, who was not far away from Xu Yun, just rolled his eyes twice. After coming back to his senses, he quickly looked at Xu Yun and confirmed:

“Comrade Han Li, what are you talking about? There is something wrong with the drawings given by the British?”

Seeing that Wang Ganchang on the other side had stopped, Xu Yun also let go of the armrests of the wheelchair, turned to Zhao Zhongyao and nodded:

“That's right, Director Zhao, if I guess correctly, the British should have made some manipulations on the drawings, or dug a hole.”

Zhao Zhongyao murmured a few times, and his originally kind and friendly face was filled with an incredibly dark color:

"But this is unlikely. Xiao Han, these equipment have been inspected once in Xiangjiang, and they have even passed through the third wheel at our base. If there is a problem, it should have been discovered long ago."

“Gan Chang and I have personally inspected these parts in the past two days, and we haven't even missed a single screw. How can there be a problem?”

 Zhao Zhongyao's tone was full of confusion, and he was shaking his head subconsciously as he spoke.

 Mentioned earlier.

This tandem electrostatic accelerator transaction is considered a big deal even in the history of the Republic, and it is well-deserved No. 1 in the field of scientific research.

Although the rabbits of this year are not yet considered powerful, the conduct of the rabbits is still the same as that of later generations.

 The price of an item depends on negotiation skills, but for a deal that has been agreed upon, rabbits ask themselves that they will not mess with the relevant data.

But on the other hand.

It is one thing to have this kind of character yourself. Rabbits are not so naive as to think that they won't do what others do if they don't do it.

 Hence, the rabbits did not relax at all about the entire transaction process from beginning to end.

To know.

Even the gas diffusion membrane machines that Mao Xiong supported for the rabbits have been tampered with, let alone European countries such as the UK. Not only their own people are at risk.

 So after receiving the tandem electrostatic accelerator from the United Kingdom, the capital immediately organized a group of reliable experts to conduct extremely careful inspections of these equipment components on the spot.

This inspection process took two full days. Except for the parts that were welded to the point where they could not be separated, the rabbits turned every module upside down.

 The final result of this round of inspection was that there was nothing abnormal about these parts, and they had not even been replaced.

Then on the night when the tandem electrostatic accelerator was delivered to the base, Zhao Zhongyao took Wang Ganchang and others for a detailed inspection.

At that time, Xu Yun was doing some theoretical assistance work in Yu Min's light nuclear group. In addition, Zhao Zhongyao and the others were also extremely experienced in this kind of hardware testing. After all, the first electrostatic accelerator in China was tinkered by the old man, so he did not deliberately Go and notify Xu Yun.

 This round of testing at the base also took two days, and the final result was that there was still no problem with the equipment.

At that time, Wang Ganchang even complained to Zhao Zhongyao in private.

　　I didn't expect that the British guy was quite a gentleman in this transaction. He was a bit of a villain and judged a gentleman's behavior. To show his respect, he planned not to criticize British food for two years.

 The result was unexpected.

At this time, Xu Yun actually said that the British had tampered with him. How could Zhao Zhongyao not be shocked?

 In a sense, Xu Yun's words are a denial of the old man's business ability.

 Fortunately, Xu Yun, who was on the sidelines, quickly realized this, so he quickly explained it before Zhao Zhongyao doubted himself:

“Ahem. Director Zhao, maybe I spoke a little hastily and failed to let you fully understand my thoughts.”

“What I actually mean is that there is no problem with the parts of this accelerator, but some additional operating steps have been tampered with.”

Zhao Zhongyao was stunned for a moment:

"Steps?"

Xu Yun hummed at him, and Lao Guo pushed his wheelchair to the wall where the schematic diagram was hung, pointed at the schematic diagram and said:

 “Look here.”

Zhao Zhongyao followed to the wall and looked in the direction Xu Yun pointed:

“Is this a protective gas?”

Xu Yun took a deep breath, nodded, and said:

“That's right, the protective gas has been manipulated.”

Hearing this, Zhao Zhongyao once again showed a hint of astonishment on his face. It could be seen that the big boss must be quite surprised at this time.

He thought that there might be a problem with the ion source, or that the parameters of the beam tube had been changed. He even thought about whether the wires were over-pressured, but he did not think about the protective gas.

 Mentioned earlier.

The structure of the tandem electrostatic accelerator has a total of seven modules:

 High voltage generators, ion sources, accelerating tubes, analyzers, voltage stabilization and control systems, and vacuum systems.

The high-voltage generator is regarded as a startup module, and its main function is to supply the cathode and anode of the X-ray tube with DC high voltage and filament heating voltage.

Mainly composed of high-voltage transformers, X-ray tube filament transformers, high-voltage rectifiers, transformer boxes, high-voltage sockets and other components.

Of course.

There is no need to understand the specific functions of these components. Just the word "high voltage" makes it easy to think of another thing - this kind of equipment must be equipped with high-voltage gas with strong insulation during operation.

 Follow the operating instructions given by the British.

 The high-pressure gas required by the high-voltage generator is argon, which is also a rare gas widely used in industry.

Unlike nitrogen, which is very active at high temperatures and easily reacts with some metals, argon is a very reliable inert protective gas that can neither burn nor support combustion.

This thing is very common in aerospace and industrial production. The so-called "argon arc welding" of arc welding uses argon gas.

 Rabbits have a high degree of understanding of the use and use of argon gas, so after receiving the operating specifications from the British side, neither the capital nor the experts from the 221 base raised any questions.

But now it seems

There seems to be a problem with the argon gas?

Then under Zhao Zhongyao's gaze, Xu Yun couldn't help but take a deep breath and said:

“Director Zhao, argon is indeed a very ideal protective gas under general conditions—the ideal conditions here do not only refer to ordinary industries, but also cover special fields such as aerospace and missiles.”

“But in terms of accelerators, especially high-pressure accelerators, argon gas actually poses a huge safety hazard.”

 “Hidden danger?”

Zhao Zhongyao raised his eyebrows slightly and said subconsciously:

 “What's the hidden danger?”

Xu Yun glanced at him and slowly gave the answer:

“When the gradient of the high-voltage electrode exceeds a certain number, the argon gas will make the voltage factor of the axial insulation smaller, thereby losing the lateral protection effect.”

 Say it.

Xu Yun also wiped the cold sweat from his forehead.

I have to admit that the British guy's move is really vicious.

Those who worked in high-voltage accelerators in their previous lives should all know this.

 High-pressure accelerator is one of the few devices where argon cannot be used as a protective gas.

 Because unlike other scenarios, the high-voltage accelerator has two parameters, namely the gradient of the high-voltage electrode and the gradient of the insulating column.

Under the action of these two gradients, argon gas will exhibit a characteristic called under-barrier fusion, or coupling.

This coupling will cause changes in the height of the potential barrier and increase the probability of potential barrier penetration, thereby affecting the emission of the beam stream.

The principle of the tandem accelerator was mentioned earlier. This thing is a tandem mode. After the negative ions generated by the ion source are accelerated in the accelerating tube, they will be stripped of charge in the charge exchange chamber and become positive ions.

 Once this stripping process is changed, the barrier penetration probability will increase.

 Let's give an example.

 There are three one-way two-lanes A, B, and C on the road, and they merge into a one-way four-lane at a certain location.

 Originally, the traffic management bureau can achieve smooth dispatching through the traffic light cycle, that is, when AB is a green light, C is a red light, or when A is a red light, BC is a green light.

 As a result, the traffic light on a certain day, that is, the barrier penetration probability was changed.

If it's two red and one green, it's okay. At most, the efficiency is a little slower, and two lanes are wasted.

But it would be great fun if all three lights were green.

 Traffic jams are a minor matter, but in serious cases, car accidents may occur because the traffic speeds of these lanes (beam tubes) are very high. No one will stop you at 180mph.

  If the number of cars accumulates and accidents become more serious, the next thing that will be affected will naturally be the road facilities.

Think of this.

A row of thick beads of sweat suddenly appeared on Zhao Zhongyao's forehead.

There is a layer of glass between the location and operation of the tandem accelerator. Theoretically speaking, if an accident occurs to the equipment, no one will die. At least the hazard will be much lower than the explosion of explosives at the detonation test site.

Unlike explosives that can be developed again if the formula goes wrong, once there is a problem with the tandem accelerator, it cannot even be repaired.

At present, due to the limitations of industrial means, the rabbits may only be able to produce one-tenth of the parts of this accelerator.

If this equipment that the Rabbits paid a huge price for breaks down due to this reason, even if the organization does not punish him then, Zhao Zhongyao will definitely not be able to forgive himself.

  And unlike other faults.

 These pipes inside the tandem accelerator have a certain load strength, which means that under normal circumstances, they have to be used at least a few times before problems occur.

With the previously inspected parts report in front of them, the rabbits would only think that there were irregularities in their own operations and would not reflect on the British.

 It will take at least more than ten years for the Rabbits to have the industrial capacity to produce such accelerators. But what's the use of waiting until then to discover problems?

This trick is really poisonous.

Think of this.

 Lao Guo couldn't help but take a deep breath and said to Zhao Zhongyao:

"Old Zhao, I remember that there should be a similar high-pressure vessel here at the Seventh Branch Factory, right? Can you do a simple experiment to verify Xiao Han's statement?"

Zhao Zhongyao nodded with a serious face, pointed to a certain direction and said:

“Well, the capital sent our original equipment to the base this time. Although the accelerator no longer has the electrostatic analysis module, it is still not difficult to test high-pressure gas.”

The equipment Zhao Zhongyao is talking about is the 2.5MeV electrostatic accelerator assembled by the rabbits themselves, which was the instrument that was disassembled to assemble the weather Doppler radar.

Now with the arrival of the accelerator from Cambridge University, this accelerator without the electrostatic analysis module is no longer that useful.

 So after discussion in the organization, it was thought that instead of putting it in the warehouse and waiting for it to be assembled and used when the electrostatic analysis module is available in the future, it is better to transport it to the base together.

If there is a problem with some small part of the Cambridge accelerator—for example, if it is deformed due to bumps during transportation, maybe it can be filled with parts from the original one.

However, due to the special situation now, this 2.5MeV accelerator may have to be sacrificed.

Of course.

 Seeing this, some students may have a question:

 No. Since argon cannot be used as a protective gas, why didn't Zhao Zhongyao and the others discover it?

The reason is very simple. The conditions for under-barrier fusion of argon gas are relatively high. For example, the electrode gradient must exceed 80KV per centimeter.

The electrode gradient of the original 2.5MeV accelerator in normal operation was only 14.6KV per centimeter. The rabbits regarded it as a treasure, so naturally it was impossible to test its reaction with overloaded electrodes—let alone today's technological level. We still don't understand the level of under-barrier fusion, which involves the spin of particles after all.

This is just like you expect Mendeleev to realize that hydrogen can become a conductive non-metallic substance under high pressure when he is alive. This is obviously impossible.

Looking back to reality.

  The warehouse where the 2.5MeV accelerator is stored is not very far from the site, so Zhao Zhongyao quickly asked Wang Ganchang to do the inspection, while everyone stayed where they were and waited.

 Half an hour later.

Wang Ganchang trotted back to the house. As soon as he entered the door, he waved the documents in his hand to Zhao Zhongyao:

 “Teacher, the results are out!”

Seeing Wang Ganchang's face flushed, Zhao Zhongyao immediately guessed the result:

 “What, Xiao Wang, is there really something wrong with the argon gas?”

Wang Ganchang took a few breaths after hearing this, and nodded his head like a chicken pecking at rice:

“Yes, the argon gas does reduce the insulation effect after we increase the load voltage and create a gradient difference.”

“Perhaps because the load capacity of our equipment is not high, the beam tube exploded within five minutes, and the entire head module was damaged.”

Zhao Zhongyao was silent for a long time after hearing this, and finally waved his fist heavily:

 “Hey! These British guys!”

Zhao Zhongyao's actions seemed to resonate with some people at the scene. A relatively young scholar couldn't help but look at Li Jue and asked:

“Director, those British guys did this to us, can we retaliate? For example, cancel the transaction or something like that?”

The words just fell.

Lao Guo on the side immediately shook his head and explained before Li Jue:

“Don't even think about canceling the transaction. When we receive the goods, we will hand over the weather Doppler radar technology to the other party. This is the agreement to hand over the data and deliver the goods.”

“As for counterattack, do you think the British will admit it?”

“They can just show their hands and say [we don't understand the nature of matter yet] to fool them.”

 The young man suddenly fell silent:

really.

The British are not manipulating the hardware this time. It is very troublesome to argue about protective gas. If they don't admit it, there is nothing you can do about it.

But just as Lao Guo shook his head and sighed, Xu Yun's voice quietly sounded in his ears:

“Well, Gong Guo, if you want to make the British pay some price, there is nothing you can do.”
