Through a special logistics unit, Xu Chuan sent the samples to Daya Bay.
All that's left is to wait.
Although the slow neutron irradiation experiment is not particularly time-consuming, it does take some time to prepare the work and process the relevant data.
This period of time seems to be extremely long for the researchers in the Computational Materials Research Laboratory who are full of expectations.
Especially Zhao Guanggui, after a night's rest, he went to Xu Chuan's office the next day to start consulting on the situation.
Although Xu Chuan could understand the expectation and eagerness to know the results, it had to be said that the frequency with which Professor Zhao came to disturb him was almost interfering with his normal work.
After all, he is the general person in charge of Qixia's controllable nuclear fusion project. In addition to the first wall materials, there are other problems waiting for him to solve or distribute.
Fortunately, the wait did not last long.
With the highest priority marked, in early March of the Gregorian calendar, the Daya Bay Neutron Radiation Laboratory Center conducted the first batch of slow neutron irradiation experiments on zirconium oxide carbon composite materials.
After waiting for another three days, the relevant analysis data and the samples after slow neutron irradiation were transported back to the Qixia Controlled Nuclear Fusion Project through logistics.
"The test results from Daya Bay are out."
After the result report of the slow neutron irradiation experiment was sent to Xu Chuan's office, Xu Chuan called Zhao Guanggui and told him the long-awaited news.
In less than five minutes, Zhao Guanggui rushed over quickly.
"Academician Xu, how are the test results?!" Zhao Guanggui asked in an excited and urgent tone as soon as he entered the door.
Xu Chuan smiled, pushed the test report forward on his desk, and said with a smile: "Read it yourself."
Hearing this, Zhao Guanggui couldn't wait to reach out and take the test report from his desk, and started to read it.
He was very clear about sending materials to Daya Bay for testing.
Due to time constraints, as many as twelve sets of materials were sent.
These twelve groups of identical materials were subjected to different slow neutron irradiation tests in different irradiation scenarios at the same time, in order to obtain data at the same time and save time.
Of course, along with these materials, other control materials also enter the test site, such as Austrian steel, tungsten-molybdenum alloy, ceramics, etc.
These control materials are commonly used as structural materials or first wall materials in fusion devices, and can better reflect the neutron radiation resistance of the test materials.
[A set of irradiation conditions: pwr pressurized water-cooled reactor, irradiation temperature is 702k, fast neutron injection amount 5.1x102?/cm2]
[A group of irradiated materials: experimental group (zirconia carbon composite material) control group (austenitic steel, tungsten gold)],
[A group of dpa production rates: experimental group (0.17%), control group (2.4%)]
[One group of neutron penetration: experimental group (99.98%), control group (67.44%)]
[Self-healability of a set of frenkel defect pairs:...]
One item of experimental data quickly flashed across his eyes, accompanied by almost uncontrollable joy and excitement.
In the first wall material, whether it is the generation rate of dpa, the penetration of neutrons, or the self-healing properties of frenkel defect pairs, they are all very important indicators.
It is especially important for the first wall structure designed for the Dawn Fusion Experimental Device.
The first is the dpa production rate. In radioactive detection, the dpa index is usually used to indicate the number of dislocations of each atom. This does not require too much explanation.
The penetrability of neutrons represents an indicator that high-energy neutron beams can stably penetrate materials, and is the key to their ability to bombard lithium targets with high-energy neutron beams, obtain tritium, and achieve tritium self-sustainment.
As for the self-repairability of the frenkel defect pair, it represents a parameter of the degree of self-repair of the damaged lattice after being bombarded by high-energy neutrons.
Judging from the detection data passed back from Daya Bay.
no doubt!
They succeeded!
The material suitable for the first wall of controllable nuclear fusion has been successfully manufactured!
Although this was only a slow neutron irradiation test, it set a historical record.
Because, in the past, no matter which country, or which research institute or laboratory, has never produced a neutron radiation-resistant material that is comparable to the data in the test report in hand.
Clenching his fist tightly, Zhao Guanggui looked at Xu Chuan with an extremely excited expression.
"Academician Xu..., we..." He opened his mouth and hesitated in excitement.
Xu Chuan smiled. Compared to the excitement of Zhao Guanggui in front of him, he was much calmer.
"Judging from the experimental detection data of slow neutron irradiation in Daya Bay, we have indeed succeeded."
"But..." After a pause, he continued: "Compared to the real deuterium and tritium fusion in the controllable nuclear fusion reactor chamber, the neutron irradiation experiment over Daya Bay is both energy level and
Or the temperature and other conditions are not enough.”
"The highest neutron energy level in Daya Bay is only 1.2 mev, while the energy level of each neutron beam released in the controllable nuclear fusion reactor chamber is as high as 14.1 mev. And in terms of temperature, the test temperature is the highest.
It’s just 720k, which is nearly two thousand degrees lower than the real experiment.”
"So, don't be so happy. Our goal is to apply the first wall structural material of the Dawn fusion reactor, and this can only be regarded as a phased achievement."
"After it passes the complete test of the Daybreak Fusion Device, it will be completely timely to celebrate."
Of course, although this material is indeed a staged research result at present, its value is also quite astonishing.
Among other things, in the field of nuclear fission, the excellent performance of this material can largely replace cladding structural materials.
After all, although the production of carbon nanotubes is difficult, it is not very expensive.
Traditional cladding materials, such as those made of beryllium gold mixed with graphite, uranium 238 and other materials, are highly toxic both in themselves and in the smelting process because of the beryllium gold. If you are not careful, you will
Serious casualty accident.
And this kind of zirconium oxide carbon composite material has no problem holding it in your hand and playing with it.
In addition, it can also be applied in some high-tech fields such as nuclear energy, rockets, military industry, aerospace, etc.
Top-notch materials are just like this. Even if the use requirements are limited, they can be applied in many fields.
After hearing what Xu Chuan said, Zhao Guanggui, who was overly excited, gradually calmed down.
He smiled and said: "Academician Xu, you really have too high demands on yourself. To be honest, if I had independently developed this material before, I would have celebrated it with a big banquet for three days and three nights."
"This kind of material is enough to publish two or three top SCI journals."
Speaking of this, Xu Chuan smiled and shook his head, then remembered something, and then said: "Oh, by the way, you mentioned this, there is something else."
Xu Chuan tapped his fingers lightly on the table and said: "As for this material, judging from the neutron irradiation test data over Daya Bay, you also know that it has properties on the first wall of the controllable nuclear fusion reactor.
Huge application potential..."
"So for now, until our controllable nuclear fusion is completed, or until it is completely confirmed that this material cannot be used as a first wall material, the relevant papers cannot be made public for the time being."
When Xu Chuan spoke, Zhao Guanggui probably guessed what the elder in front of him meant.
In fact, it doesn't matter. Whether it is in a university, a national laboratory, or a private research institute, as long as the research results, such as patents, are completed by these units that have signed the contract, they basically belong to the research institute and experiment.
room.
Whether these are in the materials industry or other fields, these are industry practices and are stipulated in contracts, and there is nothing to dispute.
As for the researchers who made this achievement, they usually receive project bonuses and one or several papers written during the research process.
Of course, if you are one of the top experts, such as the academician Xu in front of you, if he is invited to participate in a project at a private research institute or university, you will have the opportunity to get a share of the results.
That is, he can share a portion of how much the results are sold for.
Generally speaking, it ranges from one to ten percent. The specific situation depends on the researcher's contribution, reputation, status and other things.
But many times, especially for researchers like him who have participated in national key projects, after making results, considering project confidentiality, patents, other related projects, etc., the paper may appear to be in their own hands.
Delay for a period of time before making the announcement public.
Or sometimes it may even happen that it cannot be disclosed or even applied for a patent.
However, for the vast majority of scholars and researchers, especially in China, papers are their hope, the materials and tools they use to build bridges to climb higher, and their qualifications!
Whether it is a promotion or a professional title evaluation, for example, to be promoted from associate researcher (deputy senior) to researcher (senior), what is needed is a top-level SCI paper.
But there is no way. Many times, especially when working on confidential projects, in order to avoid providing help to competitors, papers on experiments or projects that have significant help are usually postponed or stopped, or are only published in confidential form in China.
, there will be no opportunity to fully disclose it until the end of the project.
Although the paper is not complete experimental data and reports, and only partial data and related information are recorded above, these things are enough to provide competitors with a feasible idea.
Of course, when such a situation generally occurs, research institutions or laboratories will usually compensate the relevant researchers.
What is more common is that more bonuses will be given after the project is completed, and more scientific research funds will be allocated for the next project, etc.
In addition, there are also more awesome rewards. He once had a colleague who was also engaged in material research and development with an academician. After completing the work, he also found that the material had been classified and the paper he wrote could not be made public.
Then the academician directly threw the two material papers he had written to him.
The result is one top-level sci paper in exchange for two top-level sci papers.
For a scientific researcher, this kind of thing is probably a blessing from heaven.
After all, many times the evaluation of professional titles or promotions depends on the number of papers you publish and the grade of journals.
Under the same grade, one article is replaced by two. Isn’t this pie in the sky?
To be honest, if possible, he, Zhao Guanggui, would also want this!
Of course, it is also acceptable to postpone the publication of the paper if it is not possible to pay more bonuses.
After all, it is the result of a super project such as controllable nuclear fusion, and it is in the field of first-tier materials, so its influence is naturally huge.
Of course, these compensations are actually based on good trends, or meeting a good boss.
Sometimes, if you don’t have an idea and encounter a relatively bad leader or boss, you will be cheated.
You young man, don’t be so utilitarian, it’s just a paper. Anyway, you still have so much time for scientific research. As a human being, you must have a spirit of collective dedication and know how to be grateful. The research institute will give you a salary and a bonus.
I have provided you with clothing and housing for so many years, and I have given you so much scientific research funding as promised, but it is just for a paper. Are you still being wronged?
If you, young man, go back and work hard, you won't be wronged in the laboratory later. Don't waste your time on fame and fortune.
To be honest, these types of things are actually pretty good.
To be more serious, I will directly take your first work and the thesis you wrote, give you a second work, and then talk about bonuses and performance. If you talk back and get exposed, you may be fired directly.
These phenomena also exist in academic circles.
Of course, Zhao Guanggui was not worried about this happening to the person in front of him.
In the eyes of this old man, what does a piece of sci mean?
Computing is a top-level SCI paper such as "Nature" and "Science", and it is nothing in the eyes of this elder.
After all, don’t you look at how many top world problems he has solved.
He has solved two of the seven millennium problems in mathematics alone.
What he was more concerned about was how he would compensate the elder for his arrogance.
.......
Opposite me, Xu Chuan saw the expectation on his face, smiled and said, "Don't worry, the relevant compensation results will not disappoint you."
"Whether it's material bonuses or related honors, I won't treat you badly."
"Including the paper, for now, my personal opinion is to postpone the publication, but it needs to be discussed later. If it is later confirmed that the paper cannot be made public, the institute will compensate you for at least two top sci-fi papers in the material direction.
, both the first author and the corresponding author can write your name, and it will be counted as your independent research."
Upon hearing this, Zhao Guanggui's eyes lit up and he blurted out: "I am willing to obey the arrangement!"
