Chapter 538: No Obvious Radiation Damage!
Huaguo, Jinling.
STAR Device Research Institute.
"This is coming in?"
Following Lu Zhou past the gate of the research institute, Hou Jinli looked around with some curiosity.
Although he has been coming to Jinling from the University of Science and Technology for more than half a year, and the project is somewhat related to the Star stellarumer, this is the first time he has come here.
Before that, he had only heard some rumors about the institute at best.
For example, the institute is currently being secured by the military districts in the region.
For another example, maps such as Baidu and Gaode cannot be navigated here.
However, when he came in today, he found that the situation here was completely opposite to what he had imagined......
The security here doesn't seem to be as tight as it seems?
Lu Zhou smiled: "Otherwise? ”
Hou Jinli scratched the back of his head embarrassedly.
"I thought the secrecy would be tighter."
At least it's like subway security, take a metal rod and sweep it twice on your body or something.
"The security department in the station is a member of the army, so you can rest assured that you can't get close to it at all. As for confidentiality...... If even you can see it, then it's not a secret," Lu Zhou said, raising his chin towards the side of the road, "See there?" ”
"Where?"
Subconsciously looked towards where Lu Zhou was pointing, but Hou Jinli didn't see anything except a knee-high green belt.
“…… What's there? ”
Lu Zhou: "There's a camera hidden there, you can't see it." ”
Hou Jinli was stunned: "Then how can you see it?" ”
Lu Zhou: "I've seen the surveillance video. ”
Hou Jinli: "......"
From two blocks away to here, the surveillance along the way is basically dead-end.
Not only that, but on the basis of manual review, it is also paired with face recognition and big data analysis. If a non-resident wanders around the area for a long time, without even being close to the institute, someone will come and talk to him.
And this level of security is also recent.
After all, China is now in an increasingly delicate position within the ITER organization, and the United States' interest in controlled fusion technology gives reason to believe that they may have some crooked ideas to try to obtain relevant information from outside the negotiating table.
In any case, it's right to be careful.
And these things don't need Lu Zhou to worry about.
Naturally, someone will do it for him in a place where he can't see.
With Hou Jinli through the access control at the mouth of the tunnel, the two went straight to the laboratory embedded in the mountain.
By the time the two arrived, the researchers in the lab had basically arrived.
After a month's overhaul, the STAR unit has been restored to its best condition.
Although the word "best" may have to be put in quotation marks, after all, the swelling of the structural material cannot be completely eliminated, but with the experience of the previous pilot fire, this time as long as the fuel injection dose is controlled, it should not be a big problem.
Take 10,000 steps back, even if there is an accident......
That's worth it, too!
Although the internal neutron irradiation environment of the stellarator and the tokamak is similar, there are still subtle differences. Aside from the ethereal honor of "witnessing history", this is why he chose the Star device instead of the East or other tokamak devices for his experiments.
Seeing Lu Zhou appear at the door of the laboratory, Sheng Xianfu, who was in charge of the on-site command, immediately walked over and reported the situation here to him.
"All the preparations have been completed, and the experiment is ready to begin."
Lu Zhou: "Did you put the sample in?" ”
Sheng Xianfu: "It's already been put in." ”
Lu Zhou nodded: "Then let's get ready to start." ”
Sheng Xianfu: "Yes! ”
There is no superfluous communication.
After receiving the order, Sheng Xianfu immediately returned to work.
Hou Jinli took a deep breath and looked at the experiment that was about to start, his whole body was tense and almost trembling.
40 billion scientific research project, he has never participated in such a major project.
If the device fails, will he be held responsible? If the LPC-1 material didn't work, or if they missed a peak during XRD testing of the sample, the experiment went down the drain......
Although these were impossible things, it still made him feel numb.
After all, he had never thought about these questions before he stepped into this laboratory.
Glancing at Lu Zhou's back, Hou Jinli fell into deep thought.
If he felt this heaviness just by standing here, then what kind of pressure did Professor Lu bear?
I always feel terrible just thinking about it......
Looking at the busy staff in the laboratory behind the floor-to-ceiling windows, Academician Pan, who was standing next to Lu Zhou, frowned, and a little worried look appeared in his eyes.
"Are we really going to use the Star device for this experiment?"
"This is the best choice," Lu Zhou nodded, and said with a blank face, "If the LPC-1 material proves to be effective, I will immediately start the construction of the demonstration reactor." ”
"Is the liquid lithium neutron recovery system solved?" Academician Pan glanced at Lu Zhou unexpectedly, "There are also magnetofluid generator sets." These two questions are critical, right? ”
Lu Zhou: "In my opinion, it is completely feasible to solve it while constructing. At least compared to neutron irradiation resistant materials, these two problems are not critical difficulties. ”
Academician Pan: "I don't know why you're in such a hurry, but now there are five or six years to go until 2025. It is important to seek speed in stability, but in any case, stability is still the first priority...... Don't rush it. ”
"Hmm," Lu Zhou nodded, "I see." ”
Academician Pan shook his head.
He knew that Lu Zhou didn't listen to his advice, and the sentence "I know" was mostly just a polite perfunctory. Perhaps because he is used to working alone, this person is too assertive in his research.
However, there is no other way for him to believe it now.
After all, he has been far away from the front line of research work for too long, and only the prestige of the so-called pioneer is left in this field.
It's nothing to help beat the side drum outside of research, and sometimes Lu Zhou can help make up for the lack of tactfulness in dealing with other research institutes.
But in specific experiments...... I really can't give any advice.
With a sigh, Academician Pan looked at the steel behemoth behind the floor-to-ceiling window.
Now all he can do is pray.
……
More than two dozen samples were installed in the reflection chamber.
This time, there was no camera to record everything, let alone a reporter interview.
Because Lu Zhou deliberately mentioned to the city government when he reported that the key content of this experiment involving fusion research is not suitable for publicity.
Fortunately, he mentioned it.
Otherwise, the city party committee really has plans to send reporters to do propaganda for him.
Taking a deep breath, Sheng Xianfu looked at the table below.
After getting Lu Zhou's eye signal, he ordered in a deep voice.
"Let's start experimenting!"
Almost as soon as he finished speaking, liquid helium began to inject into the SG-1 superconducting magnet, soaking the circle of graphene wires that surrounded the outer orbit of the stellarator.
As the resistivity of the outer field coil drops dramatically, a huge current begins to pass through the coil, and with the assistance of the control coil, a perfectly closed magnetic field is formed along the orbit of the stellarite.
Confirming from the computer that the magnetic field form is intact, Sheng Xianfu continued to order large.
"Fuel it!"
A mixture of 1 mg of deuterium-tritium was injected from the catheter into the inside of the reaction chamber.
At the same time, the microwave heating unit begins to heat the gas molecules in the reaction chamber.
Almost at the moment when the gas molecules were ionized into plasma, a brilliant film like an aurora was spread inside the geometrically beautiful reaction chamber track.
It looks like a fluttering cicada's wings, as if a wisp of dust can shatter it.
However, the heat contained in it is enough to cut through all the armor in this world.
Fortunately, it is controlled by an invisible hand......
The magnetic field confines the plasma and remains stable.
The temperature and density of the plasma continue to climb until it is close to the tipping point of fusion ignition.
At this moment, everyone's fists couldn't help but clench.
In an instant, the white light in the lens flickered, and the picture turned snowflake white.
At this moment, in the orbit of that stellar, the most terrifying energy of this planet is brewing.
Although this process only lasted less than three seconds......
"Turn off the microwave heating device!"
As the heating device is switched off, the heat is continuously removed by the deflector, and the fusion reaction comes to an abrupt halt.
After waiting for the device to cool down, the staff in protective suits quickly entered the reaction chamber and removed valuable samples from it.
These samples are sent to a dedicated testing chamber for testing of their DPA values, HE residues, and other attributes.
At the same time, the personnel in charge of overhauling the equipment also rushed into the equipment and began to evaluate the damage to the structural materials, first wall materials, deflectors and other components.
Looking at the samples that were sent to the testing room, Hou Jinli also followed and assisted the researchers of the STAR Research Institute to complete the testing work.
In less than an hour, the test results were in.
The moment the report was brought to the lab, almost everyone gathered around, whether they could read it or not.
The hand holding the report was trembling, Hou Jinli looked at Lu Zhou, and then at the researchers he had never met at the scene, and said excitedly: "...... The neutron beam basically passes through the material, and the interstitial atoms basically backfill the origin grid! All the data show that the material has excellent resistance in the high-energy region neutron irradiation environment, and there is no obvious irradiation damage! ”
Sheng Xianfu held his breath.
Academician Pan's eyes widened.
Everyone present was moved by their expressions and their faces were happy.
The neutron beam basically passes through!
No significant radiation damage!
Hearing this sentence as well, the corners of Lu Zhou's mouth hooked up with a smile.
This is probably the best news he has heard this year!
