Chapter 99

In the test field, the Spherical Tokamak device here is only 20 meters in diameter. Compared with the large circulation fusion devices weighing tens of thousands of tons in other countries, it is a "small man".

There is no doubt that it is much more difficult to form high temperature and strong magnetic field in a smaller device and control the output energy of fusion reaction.

In order to build this Spherical Tokamak device, more than 50000 constructors and experts have fought for it in three years, overcome various difficulties and broken through more than 10000 world-leading technologies!

In particular, the new room temperature and atmospheric pressure superconducting materials, high temperature and high pressure superconducting materials and the inner wall materials of fusion devices have become a new milestone in the history of human materials!

"Jinwu" is the name of the device, implying the "artificial sun" made by human beings.

"Report, the last inspection is completed and there are no abnormalities," a researcher Hui reported.

In the main R & D team, Du Xingyu, Zhou Ziang and others seriously reviewed various data.

Although it has been simulated countless times in the computer, everyone still has no bottom in his heart when he really wants to carry out the fusion reaction test.

This is the energy source of stars. Can humans really control it?

"Let's start." Du Xingyu whispered. He had been waiting too long.

With a technology simulator, he has never studied a project for five years. In the science and technology simulator, in order to reach the current level, he has consumed one billion energy points and conducted countless simulations. Every detail, from material to device design, is a huge workload.

"Prepare to awaken Jinwu!" although Zhou Ziang is old, his eyes are firm. He is eighty-four years old and is dying. This may be the last big project in his life.

But as long as it can be made, it will be famous in history and there will be no regrets in this life!

The whole project team, more than 50000 participants are watching. They are nervous and full of expectations.

It can be said that this experiment is related to the future of all mankind. At present, fusion devices made in several other countries, including the latest one in the United States, cannot be used to power the "asteroid impactor".

There is not much time left for mankind!

In the main control room, everyone looked at each data through the monitoring equipment.

"Start ignition!" Du Xingyu pressed the button. Ignition here refers to heating the fusion reactor.

Only when the reaction raw materials are heated to hundreds of millions of degrees Celsius can the fusion reaction occur.

The raw material deuterium tritium is stored in the center of the Spherical Tokamak under the constraint of the magnetic field.

The laser igniter began to heat the raw materials. Hundreds of lasers hit the target position almost at the same time. The temperature of the reactants rose rapidly from thousands of degrees Celsius to tens of thousands, tens of millions, until it reached more than 100 million degrees Celsius!

"How about the inner wall?" senior researcher Luo Yongzhen was worried that such a high temperature, even without direct contact, would be a very harsh test on the inner wall. If the inner wall is melted, the test will fail directly.

The fusion reaction has begun. Countless particles impact the isolation layer. The divertor diverts the charged particles in the discharged shell layer to a separate room. The charged particles bombard the baffle and become neutral particles, which are pumped away. At the same time, a large number of neutrons escaped and hit the inner wall.

Huge energy is being generated. At this moment, "Jinwu" is gradually waking up!

"This is just the beginning!" Du Xingyu whispered. "High temperature plasma has been generated. Pay attention."

At this time, the discharge reaction has begun, and a strong current is released through the output device.

"Start to output!" people are looking forward to it. At least so far, Jinwu device has begun to output energy.

"The cooling system is stable."

"The output frequency increases by 2 million% in ten seconds... The Q value has reached 1.7!"

"External radiation is within the safety value."

Time is still in the past. It's too early to say that the experiment was successful!

"Fifty minutes!" a researcher became excited when he looked at the time. The output time has exceeded the nuclear fusion reactor in the United States and become the most in the world!

"The energy released has exceeded 49 times the input!"

"Are we going to succeed this time?" when everyone was full of expectations, the instrument showed that the fusion reaction began to weaken.

"What's going on?" Zhou Ziang wondered.

"The high-temperature plasma is reduced! The temperature in the device is falling, and the nuclear fusion reaction is about to stop!" Du Xingyu frowned. Although they have broken the world record this time, they still failed to succeed in one fell swoop.

"Failed again?" someone's face darkened.

"No." Du Xingyu did not lose heart and encouraged the public: "nuclear fusion has been stable for nearly an hour. This time the problem should not be big. First cool the device and then detect the problem."

"Come again!" every researcher here has experienced countless failures. This blow is nothing. They soon regrouped and began to look for problems.

At two o'clock in the morning, at the Atomic Energy Research Institute, Du Xingyu detected the residual materials of nuclear fusion and finally found the problem.

"It's waste!" said Du Xingyu. "After fusion, the temperature of alpha particles in the plasma decreases and helium ash is produced. Our magnetic constraints are too strong, so that helium ash cannot be discharged in time. When it accumulates to a certain amount, the fusion reaction stops. It's like burning a boiler, there are too many ashes and the combustion cannot continue."

"So we need to find a new magnetic confinement scheme to discharge helium ash under the condition of ensuring plasma control!" the nearby nuclear physics expert immediately understood his meaning.

"Yes!" Du Xingyu immediately began simulation research. He said confidently: "tomorrow, tomorrow we will be able to come up with a new scheme!"

The next day, the Jinwu project carried out a new scheme transformation and started the nuclear fusion control test again.

……

The meeting of the human Guardian alliance has reached its fifth day, and a new scheme has been generated.

This time, all parties acquiesced in the emergence of plans such as PlanB and Planc. Because countries have found that perhaps mankind can not resist the disaster of asteroids.

If things really get to the worst, mankind will send some elites into space, build cities on Mars and wait for the disaster on earth to pass.

Of course, this is only the final plan. At present, we still focus on united efforts to tide over the crisis. Up to now, every country dare not reserve any more and will cooperate fully.

So the assembly began to elect the supreme commander of the guardian alliance.

"At present, we have four candidates, namely, cosmologist barkhaus from Germany, space defense expert O'Connor from the United States, astrophysicist Peter vinocchio from the hairy bear country, and Mr. Du Xingyu, a famous scholar in many fields in China." the supporters of the conference announced.

With regard to the selection of commanders, all parties agreed that we should break the Convention and let professional leaders be non professional, so these experts were nominated. As for other matters, it is natural for competent people in relevant fields to help deal with them.

Du Yuxing became one of the candidates although he did not appear in person. After all, he put forward the whole "Death Star crisis response plan", and he is leading several successful projects at present.
