The ignition was originally scheduled for the next day, but because Lin Dong and a certain leader who received the news were going to the scene in person, the time was moved back by four hours, and it was not until 13:55 in the afternoon that the final preparations began at the scene.

Su Yichen and Lin Dong talked softly, and then nodded slightly to Chen Yuan, who was not far away, indicating that they could start.

Although Su Yichen is the core figure of the 863 project from design to implementation, Chen Yuan is the chief engineer of the 863 project anyway, so it is more appropriate for him to issue today's official ignition test order.

Chen Yuan was very grateful to himself for this honor, and he knew very well that this official ignition test was the most glorious moment that could leave a lifetime in his scientific research career, and its importance was no less than the great achievements of his predecessors in the past. Facing everyone's attention, Chen Yuan took a deep breath, took a half step forward, and then announced loudly with a voice trembling slightly from excitement: "Project 863, a controlled thermonuclear fusion device, the first official ignition test preparation!" ”

The scene was silent, but everyone's eyes were on Chen Yuan. Chen Yuan calmed down and continued: "No. 1 vacuum chamber! ”

"Vacuum chamber No. 1 is ready!"

"Vacuum chamber two!"

"Vacuum chamber No. 2 is ready!"

"Number three......."

"Vacuum chamber No. 3 is ready to complete ......!"

"Magnetic field beam system!"

"The magnetic field of the beam pulse is normal!"

"Pressure."

"Normal pressure!"

"Electromagnetic range."

"Range is normal!"

"Laser ignition device."

"The laser ignition is normal!"

"Accelerator."

"The accelerator is normal!"

"Computing control system."

"The computing control system is normal!"

"Energy Conversion System."

"The conversion system is fine!"

"Cooling system."

"The cooling system is ...... normal!"

With Chen Yuan's confirmation and the repetition of the technicians on the scene, the entire real room echoed with the answers between them, and although Lin Dong, who was standing beside Su Yichen, maintained his composure on the surface, he could show the excitement and anticipation in his heart from his hands holding crutches.

Gently put his right hand on the back of Lin Dong's hand, Su Yichen nodded to him with a confident smile, Lin Dong calmed down his already boiling heart, but his eyes still stayed on the device in front of him.

"The final countdown is 90 seconds and ready!"

"The 90-second countdown begins, 89...... 88…… 87…… 86……。 ”

The red LED light danced the countdown of time, and when the number on it finally jumped to 0, Chen Yuan raised his right arm and waved it downward, and the order to ignite was officially issued.

The start ignition button was pressed, and there was a buzzing sound in the quiet room, which came from inside the device, and everyone knew that this was a normal reaction to the start of the device, and the humming did not last too long, as the vacuum chamber and the magnetic field beam reached the critical point at the moment, the accelerator began to operate, and the laser ignition device was running at the same time.

The sound of "pop" came relatively suddenly, and it sounded like a small firecracker exploding, and the leaders who came to inspect the work entrusted by the chief were suddenly startled and just wanted to ask if there was something wrong. At this time, Li Chen, who was accompanied by a technical expert, whispered to the leader on the side that this sound was a normal reaction of ignition, confirming that the deuterium atoms ejected by the accelerator had started the fusion reaction at the high temperature generated by the laser ignition device.

"This reaction doesn't cause problems with the device, does it?" The leader asked with some trepidation.

Li Chen couldn't laugh at this question, didn't this leader know that this was originally a controlled thermonuclear fusion device? He didn't know how to explain this kind of layman, and after thinking about it, he could only tell him that there would be no problem with this qiē, and according to the current number of ignition runs, it was within the control range.

"That's good...... That's good. In a relaxed tone, the leader seemed to feel that he was also making a big fuss, he smiled self-deprecatingly, looked around weakly, and only relieved when he found that everyone did not notice his gaffe just now, but continued to look at the device and the number of feedback.

The ignition is running normally, which is a good start, not only Chen Yuan himself, who is in charge, but also everyone present is excited. However, this does not represent the success of the actual test, as the design will need to test the sustainability and stability, including the energy efficiency gain and loss ratio of the energy conversion, to determine whether it is truly successful.

The responsible personnel were working nervously, and the number of jù was summarized by the control system, and finally quickly passed to Chen Yuan. At this time, Chen Yuan was not reserved, he directly asked Su Yichen and Lin Dong to watch the number together, although he was the chief engineer, but Chen Yuan himself knew that compared with Su Yichen and Lin Dong, especially Su Yichen, he was the real soul of this project and plan.

"Pay attention to the rhythm of the ignition frequency, and observe and report the operation of the vacuum chamber at any time." Su Yichen was not polite, took a few glances and directly issued this order, and the technicians in charge of these two aspects immediately followed up and adjusted according to Su Yichen's requirements, staring at them to death.

"How's the energy conversion?" Lin Dong focuses on another aspect, the ultimate goal of controlled thermonuclear fusion is to complete the energy conversion to replace the primary energy currently used. If this step is not achieved, or if the energy consumed by the entire device in operation exceeds the energy it converts, then even if the actual test is successful, it will be a failure in some sense. What's the use of a device where the input is greater than the output and has no practical value?

"Elder Lin, look." Chen Yuan hurriedly handed a number jù to Lin Dong, and after Lin Dong took it, he looked down and immediately looked up and asked, "Is there a problem with counting jù?" ”

"Absolutely no problem!" Chen Yuan replied categorically, with a proud smile.

"Good! All right! Lin Dong also smiled, from this number to confirm that the actual energy conversion rate of the current controllable thermonuclear fusion device has reached more than 50%, don't look at this number is inconspicuous, in fact, it is already very remarkable. You know, in 1970, the former Soviet Union improved the original tokmak device and achieved the first energy output, but what is this energy output? According to the energy gain factor, the Q value, this Q value is about 1 part per billion, which can only be measured with the most advanced equipment at the time.

After decades of research, this Q value has risen to 0.6, but the Q value does not mean a qiē, and if the controllable thermonuclear fusion device wants to enter the practical stage, then its operation time and completeness must be guaranteed on the basis of maintaining the Q value.

This is especially true of the running time, which is also an important part of today's actual testing. As time passed, when the time displayed by the LED digital light was about to reach 16 minutes, many people looked at the beating numbers at the same time.

Previously, the Chinese Tokmak device had a running time of 1,000 seconds, and 1,000 seconds was converted to 16 minutes and 40 seconds. Now that this duration is about to expire, it will be interesting to see whether it will be a miracle or an abrupt end.

16 min 36 sec...... 37 seconds...... 38 sec...... 39 seconds .......

In the last few seconds, the time passed so long, holding my breath and staring intently at the beating of the numbers, when the numbers finally crossed 40 seconds in an unstoppable attitude, and when it was displayed at 41 seconds, the scene suddenly erupted into jubilation, no matter what happened next, now they have created a miracle.
