Chapter 624 A Vicious Plot

"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 passed.

Zhao Zhongyao, who was not far away from Xu Yun, just rolled his eyes twice. After regaining consciousness, 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 armrest of the wheelchair, turned to Zhao Zhongyao and nodded:

"Yes, Director Zhao, if I guessed 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 impossible. Xiao Han, these equipment have been inspected once in Xiangjiang, and they have even passed through three rounds of inspections at our base. If there are any problems, they should have been discovered long ago."

"Gan Chang and I have personally inspected these parts in the past two days. Not even a single screw has been missed. 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.

The transaction of this tandem electrostatic accelerator is considered a big deal 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, the Rabbits ask themselves that they will not mess with the relevant data.

But on the other hand.

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

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

To know.

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

Therefore, 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 I deliberately went to inform 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.

He said that he 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. In order to show 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 were denying the old man's business ability.

Fortunately, Xu Yun who was on the side quickly realized this, so he quickly explained 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 manipulated."

Zhao Zhongyao was stunned for a moment:

"Steps?"

Xu Yun hummed at him, and Lao Guo pushed his wheelchair to the wall with the schematic diagram, 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... 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 something wrong with the ion source, or that the parameters of the beam tube might have been changed, or that the wires might have been overpressured, but he didn't 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.

Among them, 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.

It is 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" in them will easily remind you of another thing - this kind of equipment must be equipped with highly insulating high-pressure gas during operation.

According to the operating specifications given by the British.

The high-pressure gas required for the high-voltage generator is argon, which is also a rare gas with a wide range of industrial applications.

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.

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

But now it seems that

there seems to be something wrong with argon?

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

"Director Zhao, argon is indeed an 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 the accelerator, especially the high-voltage accelerator, argon actually has a very huge safety hazard."

"Hidden danger?"

Zhao Zhongyao raised his eyebrows slightly and subconsciously said:

"What hidden danger?"

Xu Yun glanced at him and slowly gave an answer:

"When the gradient of the high-voltage electrode exceeds a certain number, argon will reduce the voltage factor of the axial insulation, thereby losing the lateral protection effect."

After that.

Xu Yun also wiped the cold sweat from his forehead.

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

Students who were high-voltage accelerators in their previous lives should all know it.

High-voltage accelerators are one of the few equipments where argon cannot be used as a protective gas.

Because unlike other scenarios, high-voltage accelerators have 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 will have a characteristic called under-barrier fusion or coupling.

This coupling will cause the change of the barrier height and increase the barrier penetration probability, thus affecting the emission of the beam flow.

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

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

Let's take an example.

There are three one-way two-lane roads A, B, and C on the road. They intersect at a certain position to form a one-way four-lane road.

Originally, the traffic control bureau could achieve smooth scheduling through the cycle of traffic lights, that is, when AB is green, C is red, or when A is red, BC is green.

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

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

But if all three lights are green, it will be a lot of fun.

Traffic jams are a minor matter. In serious cases, there may be car accidents - because the speed of these lanes (beam tubes) is very high. No one will stop you at 180 km/h.

If more and more cars pile up and accidents become more and more serious, then the road facilities will naturally be affected next.

Swish -

Thinking 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, if there is an accident in the equipment, it is not said whether there will be deaths, but at least the harm is definitely much lower than the explosion of explosives in the detonation test site.

But unlike the error in the formula of explosives, it can be developed again. Once there is a problem with the tandem accelerator, it cannot even be repaired.

Nowadays, due to the limitations of industrial means, the rabbits can probably only produce one-tenth of the parts of this accelerator.

If this equipment that the rabbits paid a huge price for fails for this reason, even if the organization does not punish him at that time, Zhao Zhongyao will definitely not be able to forgive himself.

And it is different from other failures.

These pipes inside the tandem accelerator have a certain load strength, which means that under normal circumstances, it will take at least a few times of use before problems occur.

With the previous inspection report of the parts in front, the rabbits will only think that there are irregularities in their own operation links, and will 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 discovering problems by then?

This trick is really poisonous.

Thinking of this.

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

"Lao Zhao, I remember that there should be similar high-pressure containers here at the seventh branch? Can you do a simple experiment to verify Xiao Han's statement?"

Zhao Zhongyao nodded with a gloomy 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 not difficult to test the high-pressure gas."

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

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

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

If some small links of the Cambridge accelerator have problems - such as deformation caused by bumps during transportation, it may be possible to use the original parts to fill in.

However, the current situation is special, and this 2.5MeV accelerator may have to be sacrificed.

Of course.

Seeing this, some students may have a question:

That's not right. Since argon cannot be used as a protective gas, why didn't Zhao Zhongyao and his team discover it originally?

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

The original 2.5MeV accelerator had an electrode gradient of only 14.6KV per centimeter in normal operation. The rabbits regarded it as a treasure, so it was impossible to use the overloaded electrode to test its reaction for no reason - not to mention that the current level of technology is not yet aware of the level of sub-barrier fusion, after all, it involves the spin of particles.

This is like expecting Mendeleev to realize that hydrogen can become a non-metallic element with conductivity under high pressure when he was alive, which is obviously impossible.

The view returned to reality.

The warehouse where the 2.5MeV accelerator was stored was not far from the scene, so Zhao Zhongyao quickly asked Wang Ganchang to do the inspection, and everyone stayed there and waited.

Half an hour later.

Wang Ganchang trotted back into the house, and as soon as he entered the door, he waved the document in his hand to Zhao Zhongyao:

"Teacher, the results are out!"

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

"What, Xiao Wang, is there really a problem with the argon gas?"

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

"Yes, after we increased the load voltage and formed a gradient difference, the argon gas did reduce the insulation effect."

"Perhaps it was because the load capacity of our equipment was not high. The beam tube exploded in less than five minutes, and the entire head module was defective."

"."

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. I saw a scholar who looked younger couldn't help but look at Li Jue and asked:

"Director, those British guys treat us like this, can we fight back? For example, cancel the transaction?"

As soon as the voice fell.

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

"Forget about canceling the deal. We will hand over the weather Doppler radar technology to the other party when we receive the goods. This is the agreed information and goods."

"As for countermeasures, do you think the British will admit it?"

"They can just throw up their hands and say [We don't understand the essence of matter] to fool them."

The young man was silent:

"."

Indeed.

The British did not tamper with the hardware this time. It is very troublesome to argue about the protective gas. If they don't admit it, you can't do anything about it.

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

"Well, Mr. Guo, if you want to make the British pay a price, there is a way."
