Technology's opening live broadcast to build rockets

In the test site, the spherical tokamak device here is only twenty meters in diameter. Compared with the large-scale circulation fusion devices in other countries that weigh tens of thousands of tons, it is considered "small".

It is undoubtedly much more difficult to create high temperature and strong magnetic field in a smaller device and control the energy output of the fusion reaction.

In order to build this spherical tokamak device, more than 50,000 construction workers and experts worked hard in three years, overcoming various difficulties and breaking through more than 10,000 world-leading technologies!

In particular, new normal temperature and normal pressure superconducting materials, high temperature and high pressure superconducting materials and fusion device inner wall materials have become new milestones in the history of human materials!

"Golden Crow" is the name of the device, which means the "artificial sun" created by humans.

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

In the main R\u0026D team, Du Xingyu, Zhou Ziang and others seriously reviewed various data.

Although it has been simulated countless times on the computer, everyone is still unsure when it comes to actually conducting fusion reaction experiments.

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

"Let's begin." Du Xingyu whispered, he had been waiting for too long.

With a technology simulator, he has never spent five years working on a project. On the technology simulator, in order to reach the current level, he has consumed one billion energy points and conducted countless simulations. From materials to device design, every detail is a huge workload.

"Get ready to wake up the Golden Crow!" Although Zhou Ziang is old, his eyes are unwavering. He is already eighty-four years old and has only a few days to live. This may be the last big project in his life.

But as long as it can be done, it will definitely leave a mark in history, and there will be no regrets in this life!

The entire project team and more than 50,000 participants are paying attention. They were nervous and full of anticipation.

It can be said that this experiment is related to the future of all mankind. Now, fusion devices manufactured by several other countries, including the latest one in the United States, cannot be used to provide energy for "asteroid impactors."

There is not much time left for mankind!

In the main control room, everyone watched every piece of data through monitoring equipment.

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

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

The raw materials deuterium and tritium are stored at the center of the spherical tokamak device under the constraints of a magnetic field.

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

"How is the condition of the inner wall?" Senior researcher Luo Yongzhen was a little worried. Such a high temperature, even if there is no direct contact, will be very harsh on the inner wall. If the inner wall is melted, the test will directly fail.

The fusion reaction has begun to occur. Countless particles impact the isolation layer. The divertor diverts the discharged outer shell layer's charged particles into a separate chamber. The charged particles bombard the baffle and turn into neutral particles and are pumped away. At the same time, a large number of neutrons escape and hit the inner wall.

Huge energy is being generated, and the "Golden Crow" at this moment is gradually waking up!

"This has just begun!" Du Xingyu whispered, "High-temperature plasma has been generated, please pay attention."

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

"The output has started!" Everyone was looking forward to it. At least so far, the Golden Crow device has started to output energy.

"The cooling system is stable."

"The output frequency increased by two million percent within ten seconds... the Q value has reached 1.7!"

"Within the external radiation safety value."

Time is still passing, and it is too early to say that the test is successful!

"Fifty minutes!" A researcher looked at the time and became excited. This output time has surpassed the nuclear fusion reactor in the United States and became the longest in the world!

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

"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 asked in surprise.

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

"Failed again?" Someone's face darkened.

"No." Du Xingyu was not discouraged and encouraged everyone: "The nuclear fusion has been stable for almost an hour. The problem should not be big this time. Let's cool down the device first and then detect the problem."

"Come again!" Every scientific researcher here has experienced countless failures. This blow was nothing. They quickly regrouped and started looking for problems.

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

"It's waste!" Du Xingyu said, "After fusion occurs, the temperature of the alpha particles in the plasma decreases, producing helium ash. Our magnetic confinement is too strong, which prevents the helium ash from being discharged in time. When it accumulates to a certain amount, the fusion reaction stops. It’s like burning a boiler and there are too many ashes and the combustion can’t continue.”

"So we need to find a new magnetic confinement solution to expel helium ash while ensuring control of the plasma!" The nuclear physics expert next to him immediately understood what he meant.

"Yes!" Du Xingyu immediately started simulation research, and he said confidently: "Tomorrow, tomorrow we will definitely come up with a new plan!"

The next day, the Jinwu project underwent a new program modification and started nuclear fusion control tests again.

…

The meeting of the Human Guardian Alliance has reached the fifth day, and a new plan has been generated.

This time, all parties have acquiesced in the emergence of plans such as PlanB and PlanC. Because countries have discovered that perhaps, humans cannot resist the disaster of an asteroid.

If things really come to a worst-case scenario, humans will send some of their elites into space to build cities on Mars and wait for the disaster on Earth to pass.

Of course, this is just the last resort. At present, everyone is still focused on jointly weathering the crisis. Now, every country no longer dares to hold back and will fully cooperate.

Therefore, the assembly began to elect the supreme commander of the Guardian Alliance.

"Currently we have four candidates, namely the cosmologist Backhaus from Germany, the space defense expert O'Connor from the United States, the astrophysicist Peter Vinocci from the Bear Country, and the famous Chinese Scholar in many fields, Mr. Du Xingyu." announced the supporter of the conference.

Regarding the selection of commanders, all parties agreed that we should break the rules and let professional leaders be non-professionals, so these experts were nominated. As for other matters, naturally there are capable people in related fields to help deal with them.

Although Du Yuxing was not present in person, he still became one of the candidates. After all, it was he who proposed the entire "Death Star Crisis Response Plan", and he is leading several currently successful projects.
