Chapter 386: Not Just a Hundred Minutes!

Accompanied by the instructions in the main control room, the modified Dawn fusion device started its steps again.

This is a steel giant, with ultra-high temperature plasma of hundreds of millions of degrees in its abdomen, slowly moving towards the door called "Hope".

After countless simulations by the supercomputer, the external field superconducting coils that have been readjusted and even replaced are adjusting the confinement magnetic field in the chamber of the Dawn fusion reactor stably as expected.

The simulated high-temperature plasma composed of helium-3 and hydrogen is rotating in the chamber, just like the earth is pulled by the gravity of the sun, traveling on a predictable orbit.

Time passed bit by bit, and soon it came to forty-five minutes.

This is a key node. The last operation test stopped here. The reason is that the temperature of the first wall and the load on the high-temperature plasma that occasionally escapes the control of the confinement magnetic field have approached the limit.

As for now, judging from the various data detected in the main control room, the situation seems to be good.

Looking at the various data on the console, Xu Chuan also heard the work reports of various groups.

[The current confinement magnetic field is stable and the external field coil is in good condition! 】

【.】

【The neutron wall load of the first wall has reached 0.27MW/㎡. The current plasma load increase is expected to damage the first wall material in six hours! 】

【.】

One report after another sounded in his ears. Xu Chuan listened carefully and analyzed the relevant data.

After confirming that the current state of the Dawn Fusion Device was good, he issued the order to "continue to operate".

It must be said that after re-adjusting the external field coil and re-optimizing the control model of plasma turbulence, the state of the Dawn Fusion Device was much better than he expected.

The problems of slight magnetic surface tearing and plasma magnetic islands that existed in the simulation operation of helium-3 and hydrogen high-temperature plasma were suppressed in this operation.

So that the temperature and load rise rate of the first wall were much lower than the first operation experiment.

Sure enough, the fusion type fusion device is the way out for controlled nuclear fusion.

Of course, whether the optimized Dawn Fusion Reactor is as good as in theory and whether it can support the important task of controlled nuclear fusion still needs to be seen in the subsequent deuterium-tritium operation experiment.

That is the real test.

Time passed by little by little, and in the blink of an eye, it was close to 11:45 noon.

Since the experiment started at 9:30 in the morning, the control of the high-density plasma in the chamber of the Dawn Fusion Device has exceeded two hours.

In the main control room, after confirming that the operation of the Dawn Fusion Reactor was still good, Xu Chuan re-issued the order.

"Stop the simulation operation of helium-3 and hydrogen!"

"Received!"

Two hours of high-density plasma simulation operation, combined with the data of various monitoring indicators of the main control console and the reports of each group, are enough to prove the excellence of the optimized Dawn Fusion Device.

Two hours is not its limit!

But for Xu Chuan, this operation experiment has achieved the first goal, and the next step is real combat.

With the Dawn Device stopped running, each group and unit quickly became busy again.

To switch the operation mode from the simulated high-density plasma experiment of helium-3 and hydrogen to the real deuterium-tritium raw material fusion experiment is not a simple replacement of raw materials.

In this process, many equipment that were not prepared before had to be connected or adjusted, such as the helium ash filter, the adjustment of the water-cooled divertor, the adjustment of the plasma turbulence CNC model, and a series of other things that needed to be prepared and processed.

Even though a series of preparations had been done a few days ago, there were still many things to deal with today.

Even though it was almost noon and it was time for lunch, none of the members of the project teams left their work posts.

Of course, lunch still had to be eaten.

After all, there was a tough battle to fight in the afternoon.

The lunch boxes prepared in advance were delivered to the main control room and the staff at various posts on time at twelve o'clock.

Except for some work that needed to be checked immediately after the operation stopped at dawn, everyone took the lunch boxes and ate them, including Xu Chuan and several news media reporters who came to do follow-up interviews and reports.

People are iron and rice is steel, and they will be hungry if they don't eat.

Especially at such an extremely important moment today, everyone has to stay in good condition.

After hurriedly eating a box lunch, Xu Chuan drank half a bottle of mineral water. After suppressing the food in his throat, he quickly turned around and got back to work.

The preparations started at noon and lasted until 3:30 in the afternoon, when the relevant equipment and adjustments were finally processed.

Standing in front of the main control console, Xu Chuan looked at the re-adjusted Dawn fusion device. On that steel behemoth, it was obvious that some not-so-big changes could be seen.

He took a deep breath, looked at the time, and said calmly: "Each team reports on the work progress!"

[The external field coil has been adjusted! ]

[The plasma turbulence CNC model has been adjusted! The Dawn supercomputer is in good condition! ]

[The water-cooled divertor has been adjusted! ]

[The ICRF heating antenna is in good condition! ]

[The first wall test system is in place]

[.]

The reports sounded powerfully and excitedly in the main control room.

Everyone knows that this afternoon's test means that China's controllable nuclear fusion field is about to enter a new stage.

Xu Chuan stood in the main control room, listening carefully to the reports one by one. After the feedback from all groups was completed and confirmed to be correct, he took another deep breath and calmly issued new instructions.

"Attention all groups! The second round of testing is now starting!"

"receive!"

"receive!"

"."

With the issuance of new instructions, the Dawn Fusion Device woke up from its slumber again and began a new round of changes.

External current supply!

Liquid nitrogen and liquid helium flow in!

Supercomputers and CNC models start running!

The steady-state magnetic field rises steadily.

Goals that had been achieved before began to be repeated again. The adjusted plasma turbulence mathematical model controlled the external field superconducting coil to generate a new confinement magnetic field in the Dawn Fusion Device.

The helium 3 single particle electromagnetic detection system, which has never been used before, is also online.

As each requirement and stage was met, Xu Chuan's heartbeat accelerated involuntarily.

"Report! The current status of the Daybreak Fusion Device has reached the expected goals, and the relevant equipment is in good operating condition. Deuterium and tritium raw materials can be introduced at any time for ignition experiments."

Zhao Hongzhi, who was responsible for the overall status of the Daybreak Fusion Device, came up to report the situation.

Xu Chuan nodded and said calmly and forcefully: "Put in one milligram of deuterium and tritium raw materials! Start the ignition operation experiment!"

As the instructions were issued and responsible for various tasks, the personnel in each group of control rooms quickly became busy.

"The deuterium and tritium raw materials have been introduced!"

Upon hearing this report, Xu Chuan looked at the main console, held his breath involuntarily, and clenched his hands.

Whether it's successful or not depends on what happens next.
