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 relax their vigilance because they knew very well that the running time of 1,000 seconds was just a limit of the current Tokmak device, not the end point they wanted.
After 30 minutes, the entire device was still running as usual, but Su Yichen did not dare to slack off at all, because as the running time was longer, the probability of the equipment being in the highest. At the same time, this is also the best time to collect first-hand experimental data. The following data is constantly collected and summarized at all times. These data are the general control basis for future formal molding machines. As more data is collected, the more complete the database transmitted to the computer. The primary intelligent software of the control system can rely on this data to improve itself, thinking that the official equipment will be fully controlled in the future.
The experts present all understand this principle very well. In fact, this kind of database has been widely used in CNC machine tools. The more perfect the database, the higher the precision and intelligence of CNC machine tools will be. Moreover, the overall control system used by 863 plan is designed by Su Yichen. His primary intelligent software is of course far inferior to the intelligent brain of Pioneer, but at present, it has exceeded the highest level of similar software abroad.
An hour later, the device was still operating normally. At this time, the leader who came to inspect the work had already smiled. Needless to say, the 863 plan has made a major breakthrough. Judging from the current operating time, if it was announced publicly 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 the beginning to show his encouragement and praise to the scientific researchers, but then he saw that everyone was busy at work, and this was already at the bottom of his mouth and swallowed it back. The importance of the 863 plan was personally advised by the leader before the leader came, not to mention that even Mr. Lin is now taking action, and Chief Engineer Chen Yuan, and the unknown Director Su were analyzing the data. It was too inappropriate to speak in such a serious occasion as usual. Thinking of this, the leader could only smile bitterly and shake his head and continue to stay silently.
Nine hours passed in a blink of an eye, and the time gradually went from afternoon to late at night. The technicians in all aspects of the monitoring have changed a group of people to ensure the accuracy of the monitoring data. Even the leader couldn't stand it and went to report the situation to the leader early. However, Su Yichen, Chen Yuan, and Lin Dong were still sitting in the center of the console, closely monitoring the operation of the device.
By 4 a.m., the tired Lin Dong was persuaded by Su Yichen and Chen Yuan to go back. After all, he was old and had a bad heart. Staying up late like this could easily damage his health. Besides, no one knows how long the device can last. Maybe for one day, two days, or even longer, Lin Dong can't stop resting here.
Lin Dong himself definitely doesn't want to leave, but Su Yichen said it right. Judging from the current situation, the actual test cannot be stopped for a short time, and the next time will be long. If he is exhausted and cannot see the results, wouldn't Lin Dong leave a lifelong regret?
After persuading Lin Dong to rest, Su Yichen and Chen Yuan continued to stare. At 8 am the next morning, Lin Dong, who had only had a rest for less than 4 hours, rushed back and asked about the situation as soon as he entered the laboratory.
"The magnetic field beam beat system was partially adjusted at 5:11 am, and everything else was normal." Su Yichen, who had not closed his eyes all night, handed a record to Lin Dong who had just sat down, picked up a cup of strong tea in front of him and drank it.
Looking at the recorded data, Lin Dong nodded slightly. The situation was much better than he had imagined. He felt relieved. At this time, he noticed that Chen Yuan was not there. After asking, he realized that Chen Yuan, who could not stand it half an hour ago, had temporarily gone to rest.
"You go to bed too, I'm staring here." Lin Dong advised looking at Su Yichen with red eyes.
Su Yichen shook his head: "I'm fine. The first 24 hours are the most important part. I'll go to rest after 24 hours."
Lin Dong, who knew Su Yichen's personality, did not advise him after hearing this, because he knew that since his old friend decided, the matter would not change, and what Su Yichen said was right. 24 hours is the most critical time. As the soul of this project, Su Yichen would never leave and rest in the middle. If he was 30 years younger... no! If he was 20 years old, he might make the same decision as Su Yichen.
Chen Yuan didn't take a long break, but just took a 2-hour nap and came back. Then the three of them watched the device operation together, waiting for the 24-hour arrival.
When the 24-hour period arrived, the entire device was still operating normally. At this moment, the three of them breathed a sigh of relief at the same time, and finally showed a grin of relief on their faces. It can be confirmed that the 863 plan's project for controllable thermal nuclear fusion is basically successful, so the next step is to check the maximum duration of the current device.
In the next few days, the three people, together with the entire team of technicians, kept rotating observations. Although every minute of the incident was a surprise, everyone hoped that the surprise would last. However, when the entire device was running until the morning of the fifth day, Su Yichen decided to interrupt the actual test due to several problems.
Based on the final end time calculation, the new controllable thermonuclear fusion device ran for a total of 116 hours, 27 minutes and 08 seconds from ignition to end testing, which was nearly 420 times higher than the previous 1000-second run time of the Tocmak device. This is an unquestionable breakthrough and also proves the complete feasibility of the "Su-Adams" theory from theory to practical application.
When the final test situation was reported to the head, the overjoyed head enthusiastically commended all the technicians of the entire 863 program on the phone, and also affirmed the achievements of Su Yichen and the 781 Center. At the same time, he promised to continue to increase support for Su Yichen's research work, including the various projects of the 781 Center, and give Lin Dong and Su Yichen more and greater autonomy.
Although Su Yichen expressed his gratitude for these, he did not 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. However, Su Yichen is more concerned about the further improvement of the controllable thermonuclear fusion device. Although the entire experimental ignition test was successful, there were many problems exposed during the operation, which was also the reason why Su Yichen decisively decided to stop the test after 116 hours.
According to the current collection of test data and actual equipment analysis, there are three main aspects that need to be adjusted.
First: The problem of laser ignition control system, which is mainly reflected in the laser emitter. Since the new device adopts segmented continuous ignition, the stability of the laser emitter is not enough during long-term operation. Although it runs well in a short period of time, the longer the running time, the higher the error value of the adjusted parameter value. Although there is an intelligent system for fine-tuning control, this problem cannot be avoided due to the inherent shortcomings of the laser emitter.
Second: The combined structure of several vacuum chambers. Judging from the current situation, there is still room for improvement in the combined vacuum chamber. Using data as a reference to continue to adjust the mechanism of the combined vacuum chamber, it can further improve the entire device.
Third: and the most critical point is energy conversion. According to Su Yichen's design, the energy conversion of the device should theoretically reach up to 80% efficiency, and the experimental ignition test only maintains about 55% to 58%. Although this proportion is far higher than all Tokmak devices at present, it also satisfies Lin Dong and others, but in Su Yichen's view, this is far from enough. The large amount of energy generated by thermonuclear fusion is directly wasted nearly 25%, which does not include the theoretical consumption loss. It should be noted that the lower the efficiency of energy conversion, the more accumulation it will be within the device. This is not only a waste of energy, but also an unstable factor in the operation of the device. Therefore, Su Yichen decided to redesign the energy conversion system to reduce energy consumption, thereby improving operating efficiency and reducing the unstable factors that the device may cause.
