The running time exceeded 1,000 seconds, and most of the people present looked relaxed, but Su Yichen, including Chen Yuan, Lin Dong and others, still did not let down their vigilance, because they knew very well in their hearts that the running time of 1,000 seconds was just a boundary beyond the current Tokmak device, not the end point they wanted.

After 30 minutes, the whole device is still running as usual, but Su Yichen does not dare to slack off, because the longer the operation time, the probability of the equipment appearing is also the greatest. At the same time, this is also the best time to collect first-hand real numbers, the following numbers are constantly collected and summarized at all times, these numbers are the general control basis of the future formal molding machine, with the more data collected, the more complete the number of data transmitted to the computer, the primary intelligent software of the control system can rely on these numbers for self-improvement, in order to prepare for the comprehensive system control of formal equipment in the future.

The experts present are very clear about this truth, in fact, this kind of digital library has been widely used in the current CNC machine tools, the more complete the digital library, the higher the precision and intelligence of the CNC machine tool. What's more, the overall control system used in the current 863 project was designed by Su Yichen, and his primary intelligent software is of course far inferior to the intelligent brain of the Pioneer, but at present, it has exceeded the highest level of similar foreign software.

An hour later, the device was still operating normally, and at this time the leaders who came to inspect the work had already smiled, needless to say, the 863 project had already made a major breakthrough, and judging from the current operation time, if it was publicly announced to the outside world, it would definitely cause a sensation around the world.

Clearing his throat, the leader wanted to say a few words at first to show encouragement and praise to the scientific researchers, but then at a glance, everyone was engrossed in their respective jobs, and the words that had reached their lips were swallowed back helplessly. The importance of the 863 plan, the leader personally told him before he came, not to mention that even Lin Lao is now personally out of the horse, and the chief engineer Chen Yuan, as well as the director Su who does not know the origin of the analysis of the number jù, it is really inappropriate to speak as usual on this kind of strict occasion, thinking of this, the leader can only smile bitterly and shake his head, and continue to stay silently aside.

Nine hours have passed in a blink of an eye, and the time has gradually changed from the afternoon to the late night, and the technicians in all aspects of the monitoring have changed a group of people in order to ensure the accuracy of the monitoring numbers, and even the leader can't stay up early to report to the chief. However, Su Yichen, Chen Yuan, and Lin Dong were still sitting in the center of the control platform, closely monitoring the operation of the device.

Waiting until 4 o'clock in the morning, the tired Lin Dong was persuaded by Su Yichen and Chen Yuan to go back, after all, he is old and has a bad heart, so staying up late is easy to damage his health, and no one knows how long the device can run now, maybe a day, or two days, or even longer, Lin Dong can't be allowed to stay here without resting.

Lin Dong himself definitely didn't want to leave, but Su Yichen was right, the actual test couldn't be stopped in a short time from the current situation, and the next time was still long, if he was tired and couldn't see the results, wouldn't Lin Dong leave a lifelong regret?

After persuading Lin Dong to go back to rest, Su Yichen and Chen Yuan continued to star, and when it was 8 o'clock in the morning the next day, Lin Dong, who had only rested for 4 hours, rushed back and asked about the situation as soon as he entered the real room.

"The magnetic field beam system was partially adjusted at 5:11 a.m., and everything else was normal." Su Yichen, who hadn't closed his eyes all night, handed a record to Lin Dong, who had just sat down, and casually picked up a cup of strong tea in front of him and drank it.

Looking at the number of records, Lin Dong nodded slightly, the situation was much better than he imagined, and he was relieved, only then did he notice that Chen Yuan was actually not there, and after asking, he realized that Chen Yuan, who couldn't stay up half an hour ago, also went to rest temporarily.

"You go to sleep too, I'm watching here." Looking at Su Yichen, whose eyes were red, Lin Dong persuaded.

Su Yichen shook his head: "I'm fine, the first 24 hours are the most important link, and I'll go to rest after 24 hours." ”

Lin Dong, who knew Su Yichen's character well, did not persuade him again after hearing this, because he knew that since he was an old friend, he would not change what he decided, not to mention that Su Yichen was right, 24 hours is the most critical time, as the soul of this project, Su Yichen will definitely not leave to rest halfway, if he is 30 years younger...... No! If you are 20 years old, you may make the same decision as Su Yichen.

Chen Yuan didn't rest for long, just took a 2-hour nap and came back, and then the three of them watched the operation of the device together, while waiting for the arrival of 24 hours.

When the 24 hours arrived, the whole device was still running normally, and at this moment, the three of them breathed a sigh of relief at the same time, and finally showed a relieved smile on their faces. Now that it has been confirmed that Project 863 has been largely successful for controlled thermonuclear fusion, the next step is to see how long this device will last.

Over the next few days, the trio, along with the entire team of technicians, rotated to observe, and while every minute that passed was a surprise, everyone hoped that the surprise would continue. But when the whole device was running until the morning of the fifth day, Su Yichen decided to interrupt the actual test due to several problems.

According to the calculation of the final completion time, the new controlled thermonuclear fusion device operated for a total of 116 hours, 27 minutes and 08 seconds from ignition to the end of the test, which is nearly 420 times higher than the 1,000-second operation time of the previous Tokmak device.

When the final test situation was reported to the chief, the overjoyed chief enthusiastically commended all the technical personnel of the entire 863 project on the phone, affirmed the achievements of Su Yichen and the 781 Center, and promised to continue to increase support for Su Yichen's research work, including the projects of the 781 Center, and give Lin Dong and Su Yichen more and greater autonomy.

For these, although Su Yichen expressed his gratitude, but he didn't value anything like glory and commendation at this time, as for increasing the support of the 781 center, this is of course a good thing, but Su Yichen is currently more concerned about the further improvement of the controllable thermonuclear fusion device, although the entire real ignition test was a complete success, but there are many problems exposed during the operation, which is why Su Yichen decided to stop the test after 116 hours.

According to the analysis of the number of tests collected so far and the actual situation of the device, there are three main aspects that need to be adjusted.

First: laser ignition control system problem, which is mainly reflected in the laser emitter, because the new device is to adopt segmented continuous ignition, in a long time of operation of the laser emitter stability is not enough, although the short period of operation is good, the longer the operation time, the higher the error value of the adjusted parameter value, although there is an intelligent system for fine adjustment, but because of the congenital deficiency of the laser emitter, this problem can not be avoided.

Second: the combined structure of several vacuum chambers, from the current situation, the combined vacuum chamber still has room for improvement, with the number jù as a reference to continue to adjust the mechanism of the combined vacuum chamber, the whole device can be further improved.

Thirdly, and most importantly, it is in terms of energy conversion. According to Su Yichen's design, theoretically, the energy conversion of the device should be able to reach a maximum efficiency of 80%, but the actual ignition test is only maintained at about 55% to 58%, although this ratio is far higher than all the current Tokmak devices, and it is also satisfactory to Lin Dong and others, but in Su Yichen's opinion, this is far from enough, and the large amount of energy generated by thermonuclear fusion is directly wasted by nearly 25%, which does not include the 20% of the theoretical consumption loss. You must know that the lower the efficiency of energy conversion, the more accumulation will be inside the device, which is not only a waste of energy, but also will cause the instability of the device's operation.
