The cold wind is bleak, and for the northerners, there is no winter in the south, but the wet and cold that penetrates deep into the bone marrow is even more uncomfortable.

It's late January, and after more than two months of repeated test assembly at any cost, the first prototype has been successfully manufactured, and the laboratory is officially on track.

"Save the data, replace it with the acceleration part of the Brookhaven laboratory, stabilize the temperature at 58,000 degrees Celsius, and continue the experiment."

The temperature of the plasma inside the prototype reached 58,000 degrees Celsius, and the helium-3 atoms emitted by the accelerating parts of the Lanzhou Heavy Ion Center could no longer penetrate the plasma inside the prototype.

Lu Yi's experimental idea vividly describes that the annular plasma inside the prototype is like a river, which penetrates through it by firing multiple bullets at the river.

Then, the internal information of the river is analyzed by collecting the changes in the trajectory, force, angle, and fluctuations during the penetration of the bullet and when the water collides.

The higher the temperature, the stronger the movement of ions against each other, which can be likened to the more turbulent the water flow.

When the water is turbulent to a certain extent, the bullets fired by the pistol will be washed away, unable to penetrate the current, and the detection significance will be lost, so it is necessary to replace the launcher with a more powerful launch and replace the pistol with an anti-aircraft gun.

"Lu Lu, Xiaomeng sent a message from there, confirming that with the change of temperature and density, the turbulence phenomenon inside the plasma has changed, and this change follows fluid mechanics, but the connection between low temperature and low density and high temperature and high density turbulence has not been found."

At this time, Zhang Qing, who had been in charge of communicating with Lin Meng and studying the plasma turbulence phenomenon, walked in with a tablet, which showed a video call with Lin Meng.

"This situation has been expected for a long time, and if it were so simple and controllable, the plasma in nuclear fusion would not be a blind spot."

Hearing this expected bad news, Lu Yi rubbed his forehead and took the tablet: "First send me a copy of the data analysis report on my mobile phone, and then back up all the data, I will let someone take you back to the laboratory, and the supercomputing lease over there will be due tomorrow." ”

"Uh-huh."

On the other side of the video, Professor Lin nodded obediently and motioned to the students next to him to send Lu Yi a copy of the latest data analysis report to his mobile phone.

The 130,000TFlop/s supercomputer under construction in the laboratory has not yet been completed, but the experiment has begun, and the huge amount of data is not at all capable of being calculated by the human brain, so Lu Yi had to find a local supercomputer in Yangcheng and rent it.

Ding dong!

The customized mobile phone rang in his pocket, and the 2.3G analysis data was sent in less than 1 second.

The theoretical downlink speed of 5G reaches 10G per second, which is equivalent to a download speed of 1.25GB per second.

Of course, this is a theoretical peak, in fact, the 5G download speed can reach 300M per second, which is already living in the communication base station.

With the further upgrade of the communication network in December, at the request of Lu Yi, the communication network in Yangcheng took the lead in completing the overall upgrade, and the network speed was directly increased by 8.6 times after connecting to Lu Yi's compression chip.

Of course, ordinary mobile phones are limited by performance, and it is impossible to reach Lu Yi's customized mobile phones so fiercely, but the general download speed has also reached about 1G, and the 5G network speed before the upgrade is beaten.

The communication network is upgrading, and the company's chip shipments are also rising, with the shipment price of each chip being 208 yuan, but the order price for Huawei is only 28 yuan.

Of course, this is a profit that everyone knows, and the actual book of this chip still has more than 70% of the R & D cost, and the gross profit on the book is only 20 percent, which is the average gross profit of the industry.

After Huawei, China Mobile, and China Telecom took shares, Lu Yi's shares have been reduced to 28.5 percent.

Although it paid the price of most of the shares, it also made the company's compression chip completely the industry standard, and even if other companies developed algorithms with similar compression ratios in the future, it was impossible for him to intervene in the field of communications.

The 5G era is the era of the Internet of Things, in addition to mobile phone terminals and communication networks, there are also a variety of IoT devices that also need baseband chips and this compression chip, and the remaining 28.5% of the shares are enough to temporarily support Lu Yi's research squander.

"58,000 degrees Celsius test for the second time!"

After the accelerator was replaced with the prototype, the second test began.

There is a loss in every test, and the higher the emission intensity, the more expensive the launch parts, and the money that can be saved Lu Yi will still save.

Therefore, the low-intensity test uses the accelerator converted from the Lanzhou heavy ion acceleration component, and the high-intensity test is replaced by the Brookhaven laboratory, and the last CERN acceleration component has not been used, because the emission intensity of the current test cannot meet that requirement.

The current is stored up through the capacitor, and the powerful voltage surge to the accelerator is converted into magnetic energy to accelerate the helium-3 atoms inside, which is instantly emitted to the plasma inside the prototype at a temperature of 58,000 degrees Celsius.

A large number of helium-3 atoms are launched into the plasma in turn, and ionization occurs instantly, some of the electrons escape from bondage, and the remaining helium ions still rush forward, constantly colliding with the plasma ions in the prototype along the way to send out wave signals, and finally penetrate the plasma and crash into the target material on the other side.

Di Di Di ......

The screen inside the laboratory flashed a large amount of data, which is the collision data of helium-3 ions and plasma detected by the detection instrument installed in the prototype, including the impact intensity, velocity, impact angle and other data at the moment when the helium-3 particles finally hit the target material.

YES！

After the second test was successful, the researchers hurriedly saved the data, checked the condition of the prototype and accelerator, and then gradually shut down the prototype and accelerator, and replaced the damaged equipment parts.

"Now there are a lot of equipment parts that are lost in each test, nearly 100,000 are gone all at once."

Standing next to Lu Yi, Zhang Qing looked at the dismantled equipment parts and felt a little heartache.

With the continuous improvement of the intensity and temperature of the test, the loss of each test component is also increasing, some parts that can be used 20 times at 30,000 degrees Celsius, and the temperature is increased to 58,000 degrees Celsius may be scrapped after 5 or 6 times.

It is foreseeable that when the plasma temperature of the prototype is raised to hundreds of thousands of degrees Celsius, the cost of a test will be no less than millions.

"The water-cooled deflector of the prototype is not good, the high-temperature particles escaping through the magnetic field are too damaging to the outer wall of the prototype, and I have asked Yashan to contact the domestic EAST nuclear fusion project in the name of Xiaomeng to see if I can find them to borrow a few experts to improve our deflector and even the structure of the prototype."

Lu Yi nodded beside him, and he was also a little distressed by the burning of this money.

Now a test is just an ordinary car, and it will evolve into a test of a good car, a luxury car, and even a test is a suite in Yangcheng.

The magnetic field does not bind the plasma perfectly, and there will always be a very small number of high-temperature ions that pass through the magnetic field and irradiate the outer wall material and cause damage.

It's unavoidable, just as the sun can't completely bind its plasma.

This is also the significance of studying plasma turbulence.

Only by mastering the law of ion motion inside the plasma turbulence can the stellar mimic and even the tokmak be able to bind the plasma more optimally by improving the structure, reducing or even avoiding the damage to the outer wall material caused by ions penetrating the magnetic field, thereby improving the discharge time of the controllable nuclear fusion device and even the long-term permanent and stable discharge.

No material can withstand the irradiation of ions of tens of millions of degrees Celsius or even 100 million degrees Celsius, and this problem is not solved, and it is destined that controllable nuclear fusion will not be able to operate stably for a long time.

"In the next test, the temperature will not change, and the emission intensity will be increased by 30 percent for data acquisition."

After chatting with Zhang Qing for a few words, handing over the latest test data to her for preliminary analysis, Lu Yi began to arrange the third test at 58,000 degrees Celsius.
