The entire area of the laboratory covers an area of more than 12 acres, except for the first 5-story building, the third floor is used as a supercomputer placement site, and the upper fourth floor is transformed into a canteen, and the original physics laboratory on the first floor has also been moved to the newly built laboratory.

The materials laboratory and the physics laboratory are in the same building, and the underground is deeper than the biological laboratory, with 8 underground floors and 3 floors above ground, and the future stellarator device will be placed on the lowest floor.

Although controlled nuclear fusion will not cause a fission reactor disaster even if there is an accident, the leakage of plasma with a temperature of tens of millions of degrees Celsius and 100 million degrees Celsius is not a small safety accident.

Walking into the materials laboratory located on the negative 3rd floor of the basement, Hu Feng, who was studying by Lu Yi, asked, "Brother Hu, how is the situation?" ”

The instruments and equipment of the materials laboratory have already arrived, and the researchers are still recruiting for interviews outside, and now only Hu Feng and a few assistants he invited are conducting research in the laboratory.

"Mr. Lu......"

"Just call me Lu Lu or Dr. Lu."

Lu Yi interrupted, his doctorate had already been completed, so that he could just replace the title of Mr. Lu, who was full of copper smell.

"Uh...... Then I'll call the boss. ”

Hu Feng still knows that some people are sophisticated, calling Lu Lu is not good, and calling Dr. Lu too awkward, so it is more appropriate to call him the boss according to the title of professor when he was studying for a master's degree and doctorate.

"At present, the material used in Max Planck Labs' spiral 7-X coil is a copper oxide type superconducting material, which has a good critical parameter of magnetic field strength and a good critical current parameter.

However, its poor thermal conductivity makes it exponentially more difficult to keep copper oxide coils at superconducting temperatures, which also leads to a series of engineering problems and insufficient magnetic field strength. ”

Hu Feng showed a parameter report to Lu Yi, the so-called critical parameter of the magnetic field, which refers to the exit of superconductivity when the magnetic field strength on the surface of a superconductor reaches a certain value.

The same is true for the critical current parameter, when the current inside the superconducting coil reaches a certain limit, the superconductor will also exit the superconducting state.

As for the other critical temperature parameter of superconductors, this does not need to be explained, and the need to cool down with liquid nitrogen baths at all times explains this phenomenon.

"What's in your mind?" Lu Yi somewhat agreed with Hu Feng's words and ideas.

The fundamental purpose of the materials laboratory is to serve the stellarite for controlled nuclear fusion, so the research direction should not be to develop various new materials, but to study materials that are more suitable for controlled nuclear fusion devices.

"Graphene."

Hu Feng took another report again, but this time Lu Yi did not take the report, and said directly with a frown: "The matter of achieving superconductivity of double-layer graphene at a temperature of 1.7 Kelvin announced in March 18 last year? ”

"yes, that's it." Hu Feng nodded with some surprise.

"As far as I know, the superconductivity of graphene at that time was reflected in the two-dimensional overlap, not to mention how to study qualified carbon-based superconducting materials, it is a big problem to form this carbon-based superconducting material into a wire without losing superconductivity."

Studying controllable nuclear fusion, Lu Yi has always paid attention to the relevant international theoretical discoveries and technological breakthroughs related to this aspect, and then during this period of study and soaking in the laboratory, he himself is a scientist whose potential is about to reach 90 and belongs to the genius level researcher, and he knows all the disadvantages of graphene superconductivity proposed by Hu Feng.

"No, boss."

Hu Feng shook his head: "The real significance of graphene superconductivity is that it proves that metal materials are not necessarily required to have superconductivity, and other materials may be superconducting materials, which makes the idea of superconductivity research much broader."

Carbon-based superconducting materials, it may have a lot of promise, or it may just be a flash in the pan.

However, under the premise that metal-related superconducting materials are bottlenecked and various parameters cannot meet the needs of nuclear fusion devices, we can consider shifting the focus of research to carbon-based superconducting materials. ”

[System, how many points of theoretical data of carbon-based superconducting materials?] 】

A new technology must have a theoretical framework, and data-level parameters are the basis for guiding the actual operation, unless the material of the technology is accidentally knocked over or the wrong button is struck.

Of course, this is no more difficult than the algorithm data in the IT industry, and there are still great difficulties in converting such material technology into practical applications.

For Lu Yi, the existence of the system, in addition to discovering the potential of scientists, is also a touchstone.

There are theories on the other side of the system, which proves that this direction is feasible.

The higher the redemption points, the more useful the technology corresponding to this theoretical data is for the current civilization as a whole.

[Host, 5.43 million points, your points are insufficient]

I don't know if it was Lu Yi's delusion, he felt the system's answer hesitate.

[System, have you secretly raised prices, or are your prices inflationary again?

The theoretical data of gene error replication is only 1.2 million points, which contains the mystery of the cancer terminator and the theory of the key to genetic optimization! 】

Lu Yi subconsciously and neatly questioned the system, which has become his instinct after knowing that the system belongs to information life and has autonomous consciousness.

After all, an information life with self-awareness lives in his mind, who would not be suspicious and suspicious, and always subconsciously guard, Lu Yi was not turned into a neurotic by such a moment of insecurity, which can be regarded as his heartless character.

"Boss? ...... owner"

The system ignored Lu Yi's occasional nervousness, and Hu Feng saw Lu Yi fall silent for a while, thinking that he had a problem with his thoughts, and couldn't help shouting.

"It's okay, I'm thinking about what kind of structure carbon-based superconducting materials need to form a wire coil without losing their superconducting properties."

Lu Yi waved his hand, and finally believed in Hu Feng, a scientist's demonic thinking with a potential of 95.5, and the information reflected in the point exchange price of the low forcing system in this regard.

"Next, the focus of your research will be in accordance with your plan, Brother Hu, of course, we can also allocate a part of the research force for conventional metal superconducting materials, and the number of researchers recruited now is enough to support these research projects.

I would like to reiterate that the person in charge of the research is Hu Feng, the person in charge of your project research, and you are all at the behest of Brother Hu in the research, and my opinions are for reference only. ”

"Boss ......"

Hu Feng shouted with some excitement, but before he could say anything, he was interrupted by Lu Yi: "Brother Hu, you know the materials better than me, and leaving professional things to more professional people to do is the principle of my laboratory here, otherwise why did I ask you to come over and let you be the person in charge of the project research?"

You have the sole discretion to decide on matters related to laboratory research, just ask your assistant to give me a report on the progress of the experiment every week, you can apply for any equipment and instruments you need, and you can also find me or Xu Ying for other administrative and life matters. ”

Lu Yi's words expressed great trust in Hu Feng, which Hu Feng had never felt before......
