Great Power Technology: Domination Of The World Starts With Chips

They are a family, and Yuan Wenyun suddenly felt that he was redundant.

Thinking that the carbon-tungsten-molybdenum alloy belonged to Zhiqi Company, and the boss of Zhiqi Company was the son-in-law of his old enemy, he suddenly felt that his life was hopeless.

Without the carbon-tungsten-molybdenum alloy, they couldn't do the next experiment at all.

He could only walk to the side sullenly.

Seeing his silent appearance, Xu Kaiyang did not forget to make up the knife: "Hey, old Yuan, where are you going? Stay and have a look!"

"Can't I stand by and watch?" Yuan Wenyun turned his head and glared at the complacent old guy, then found a seat and sat down, looking at the big guy with a height of more than ten meters in front of him, feeling depressed.

Xu Kaiyang laughed a few times, patted his son-in-law, and said, "You and Xinxin are going to get married in two months, so you need to arrange the time well."

Ye Cheng nodded: "You can rest assured."

"Well, that's fine." Xu Kaiyang nodded and said no more.

At this time, a voice also came from the intercom: "Academician Xu, the inner wall has been cleaned, and the installation team has withdrawn."

"Okay! Lock the exit tightly, and conduct the airtightness test immediately!"

"Yes!"

Order after order was passed on to the teams, and each team also carried out their respective tasks in an orderly manner.

The air tightness test will be completed soon.

"The airtightness of the reaction chamber is good, and the vacuum environment and airtightness of the vacuum Dewar chamber are good."

"Okay! Check the longitudinal field coil and poloidal field coil again. The pulse power supply is sure to be ready. Give me a call to the power plant and ask them to prepare it. If the power is cut off, I will pull their heads. Report them to the Presbyterian Church!"

"Check the radio frequency heating unit as well, as well as the generator set..."

Xu Kaiyang tirelessly asked for the final inspection. This time, he must make the ignition perfect without any problems.

All the groups knew that if the experiment was successful this time, they would not be far away from controllable nuclear fusion, so everyone was in a state of excitement, and did not feel that Xu Kaiyang's request was too complicated.

In this way, after another ten minutes passed, each unit began to respond to the situation, and all were in good condition, ready for experimentation at any time.

"it is good!"

Xu Kaiyang took a deep breath and said, "The vacuum pump in the reaction chamber starts."

The reaction chamber needs to achieve a vacuum environment. Of course, it is enough to be as vacuum as possible. There is no problem if there is a little air. This is done to avoid contamination of the plasma gas that will be input later. After all, it is DT fusion, and impurities in the air are mixed in. a certain degree of influence.

"The vacuum pump is running, and the air pressure in the cabin is decreasing. It is currently 0.9 Pa, 0.8 Pa, 0.7 Pa..." 7K 妏敩

The vacuum pumps they use are relatively powerful, including the main pumping system, divertor pumping system, low-clutter pumping system, etc., and the ultimate vacuum can be as high as 0.00002Pa.

This can greatly ensure the cleanliness of the cabin and facilitate the fusion reaction of DT.

"The air pressure has reached the predetermined level, the vacuum pump has been turned off, and the airtightness is good."

After a few minutes, the voice of the person in charge of the vacuum pump rang.

Xu Kaiyang gave the order again: "OK! The cooling system is now activated! Cool down the superconducting coil!"

Because the room temperature superconductor is not used now, the superconductor inside still needs to be cooled.

Liquid helium with a temperature as low as only about 4K is injected from the pipe around the niobium-titanium alloy wire coil.

The readings on the temperature gauge began to drop rapidly.

Until finally, the temperature reached the superconducting critical temperature of the niobium-titanium alloy. In order to ensure that all parts reached the superconducting state, they needed to verify.

Otherwise, as long as there is a part that has not reached the superconducting state, a huge current will be applied later, which will cause this part to generate a lot of heat, which will affect the surrounding temperature, and finally cause the other parts of the niobium-titanium alloy to also change from superconducting. Exit from the state, the accumulated heat is getting bigger and bigger, and it is easy to cause danger in the end.

Soon they passed the test and determined that all parts of the niobium-titanium alloy had reached a superconducting state.

Xu Kaiyang instructed again: "Now start injecting deuterium-tritium gas, and at the same time, start all heating systems!"

That's the last step, they just have to wait now.

When the temperature reaches 100 million degrees Celsius, the nuclear fusion reaction will reach an extremely violent situation, and the higher the temperature, the more intense the reaction, and the greater the energy produced by fusion.

Calculated in this way, the temperature of the outer coil is as low as minus 269 degrees Celsius, while the temperature of the vacuum chamber inside is as high as 100 million degrees Celsius. These two extremes have created such a miracle.

Everyone began to look forward to it.

This time, how long can they keep this thing burning.

The last time I ignited, EAST burned for 101 seconds. This time, two minutes, or ten minutes, or half an hour?

And after that, can it stably meet the conditions of Lawson's criterion?

Lawson's criterion is to assume that the total energy provided by the plasma in the fusion reaction in the fusion reactor is converted into electrical energy at a certain efficiency, and provided to the plasma to compensate for its energy loss, so that the fusion reaction continues to a critical point.

That is to say, let the temperature generated by DT fusion itself not only convert into electric energy and other losses, but also maintain the degree to which DT fusion proceeds spontaneously. After this level, even if the outside world no longer provides heat to the reaction chamber, the internal reaction will be spontaneous. keep going.

In deuterium-tritium fusion, Lawson's criterion requires a minimum temperature of 100 million K, a plasma density of 10 to the 16th power in a unit space, and a requirement for the duration of the reaction.

Generally speaking, as long as the combustion time is sufficient, this critical point can be reached, and when the heat supply from the outside to the inside is stopped, a large part of the input energy will be saved.

So everyone is quite looking forward to that.

In this way, as time passed, the reaction chamber began to be filled with deuterium-tritium gas, and the temperature also rose to over 10,000 degrees.

However, 10,000 degrees is obviously not enough for fusion reactions to occur.

Fusion means that the nuclei of two atoms have overcome the strong interaction force and collided directly, and it is basically impossible for atoms to overcome the strong interaction force at only 10,000 degrees.

Therefore, the temperature is still rising.

Time passed quickly.

The temperature went from five digits to six digits, and then to seven digits. When it reaches the million level, fusion can already occur, but not violently. However, this part of energy can also be used to provide temperature for fusion reactions.

In this way, the temperature slowly reached the level of tens of millions, and a slightly violent fusion reaction took place, but it was not enough.

And it takes a long time for the temperature to jump from tens of millions to hundreds of millions. Of course, the temperature generated by DT fusion at this time also adds a little help to this speed.

In this way, the temperature reached 100 million degrees.
