Chapter 771 Research on Polarized Electromagnetic Fields
Compared to the daily routine of protesters "sneaking into" the underground collider pipeline at CERN, Xu Chuan is more concerned about the experimental data of the high-brightness LH-LHC collider's first "show of strength".
The collision experiment at the energy level of 35Tev is the first in the current physics community, and he is quite interested in this data.
Unfortunately, since they fell out with CERN, with the support of the old United States, the membership status they had fought for has been revoked.
In addition, the Chinese Physical Society and Chinese scholars have completely evacuated CERN, and even the restart of the LHC after the upgrade has no Chinese scholars to participate, so it is almost impossible to get this experimental data.
The only thing we can do now is to wait for the CRHPC to be completed and start the experiment ourselves.
Fortunately, the time is almost up.
Thinking of this, Xu Chuan showed a confident smile at the corner of his mouth.
The circular super-strong particle collider CRHPC, which he personally led and built, has a much higher energy level than the upgraded LH-LHC.
According to the theoretical data currently designed, the maximum collision energy level of CRHPC can reach 125Tev+, which is 10 times that of LHC. Even the upgraded LH-LHC is 3.5 times as powerful.
Although the performance of traditional detectors is weaker than that of the old LHC, the "weak light" detector designed by him personally for dark matter detectors is not weaker than the detector of 1LHC.
There are only two months left, and this heavy weapon in the physics world will be introduced to the world.
After the first round of 35Tev energy level collision test experiments, CERN attracted a large number of physicists, and it was also the beginning of the verification of the strong electric unified theory and the exploration of dark matter.
On the other hand, after maintaining the first stage of attention to the restart of CERN's work, Xu Chuan did not put his energy on this, but shifted his energy to the research of plasma and electromagnetic deflection shield.
Taking advantage of the last month or so that he can spend on this, he plans to focus his energy and lead the team to study the magnetic polariton electromagnetic shield, one of the plasma electromagnetic deflection shields.
See if he can make a breakthrough in this regard.
As for the arrangement of CERN's collision experiment, after the first round of tests, the verification of the strong electric unified theory will be carried out. In fact, there is nothing much to say, and he doesn't care too much.
Although there are many controversial voices on the Internet, some people think that this is competing with the CRHPC, which is about to be completed.
After all, CRHPC is about to be completed. In theory, China has the independent ability to verify the strong electric unified theory and gain this honor.
However, for the academic community, especially the theoretical physics community, it is not uncommon for other peers to take such public papers for verification, and it can even be said that the original author's permission is not required.
On the one hand, to verify papers in the theoretical physics community, it is often necessary to use various large-scale scientific research equipment, which is extremely difficult.
For example, the Higgs boson and Higgs mechanism of Mr. Higgs were found after the first upgrade of the LHC was completed in 2008.
That upgrade cost more than 1 billion MiGold. The value of 1 billion MiGold in 2008 is not comparable to the current 1 billion MiGold.
It can be said that the verification of this kind of top-level frontier physics theory is far more difficult than a physicist can solve. The only hope is the entire physics community.
Even if the entire physics community works together, there may not be hope.
For example, Edward Witten's string theory.
I am afraid that there may not be hope to see it in two centuries.
On the other hand, for the academic community.
The importance of the proposer of the theory is greater than the discoverer and research institution.
For example, the Nobel Prize, according to convention, the Nobel Prize will not award the medal to the discoverer of the particle, nor will it reward the researchers and institutions that operate the hadron collider.
The Nobel Prize is more "inclined" to be awarded to the proposer or improver of this theory.
Because in the general view of the academic community, the work of the former two is important, but not of decisive importance.
Of course, this is not an absolute situation, and sometimes there are exceptions.
In cases where the theorist has passed away or has won the prize, or has designed groundbreaking experiments and made outstanding contributions, the Nobel Prize may be awarded to others.
For example, the weak-electromagnetic unification theory was awarded to Weinberg, Glashow and three others in 1979, and was also awarded to Carlo Rubbia and Simon van der Meer in 1984.
The reason is that the latter two made decisive contributions to the large-scale project of discovering the W and Z field particles of weak interaction transmitters.
From these aspects, Xu Chuan is not worried that CERN will verify the strong-electromagnetic unification theory before CRHPC and take away his honor.
CRHPC, on the other hand, does not have much to do.
After all, CERN can really be said to have worked hard this time, completing the upgrade of the LHC before CRHPC.
However, these things do not need to be paid too much attention. Even if CERN completes the verification of the strong-electromagnetic unification theory first, what is left for CRHPC will only be more important in a sense.
Institute of Energy Research.
At this time when most people are preparing to go home after work, the lights in several laboratories in the corner of the Institute of Physics are still on.
Especially in the innermost laboratory, in a room of about 100 square meters, about six or seven researchers are surrounding the instruments on the white plastic table in the center of the empty laboratory.
Everyone's face can be seen to be obviously haggard, even dark circles and bloodshot eyes, but everyone's eyes are full of expectations, but more of disappointment.
The plasma wall in the plasma electromagnetic deflection shield technology was handed over by Xu Chuan to the researcher named Luo Ming, and the more difficult magnetic polaron electromagnetic shield was studied by him in the more than one month before the official start of CRHPC.
And the "simple" device that looks like a "router" on the white plastic table in front of them is their latest experimental product.
What is a magnetic field?
In layman's terms, this is a question that even a junior high school student can answer.
It is a special substance that cannot be seen or touched. It is not composed of atoms or molecules, but it exists objectively. The magnetic field has the radiation characteristics of waves and particles. It exists in the space around magnets or electric currents, so that the interaction between magnets can occur through the magnetic field as a medium, even if the two are not in direct contact.
The basic characteristic of the magnetic field is that it can exert a force on the moving charges in it. This force or torque comes from the influence of the magnetic field on the electric current and the magnet.
The electromagnetic shield in science fiction is based on this principle.
But science fiction is science fiction after all. To create such a shield, it mainly depends on two conditions.
The first is to have enough energy to supply electromagnetic shields and plasma shields for continuous work. Because the energy shield needs to ensure that there are enough particles flowing continuously in a fixed area.
This is easy to solve for the Xinghai Research Institute.
You can choose alternating current or direct current. The former can be directly powered by a controlled nuclear fusion reactor, and the latter can be provided by a large-scale lithium-sulfur battery field.
But the second point is difficult.
Putting aside energy, the most core point of various shields is to have the corresponding technical ability to control the shield device, to ensure that the particles in the energy of plasma shields, electromagnetic shields, etc. will not disperse, and to be able to control the particle flow direction of the energy shield in time against external attacks.
This cannot be done before the strong electric unified theory is perfected.
Very simple, the theory does not support it.
That is, before the strong electric unified theory is perfected, the monopole of plasma field and magnetic field is still just a speculation. The physics community does not know whether it really exists, nor does it know how to achieve it.
After the strong electric unified theory is perfected, the monopole of magnetic field and plasma field can be completed by the polaron system of the strong electron-phonon interaction system.
But theory is theory. If this theory is transformed into applied technology in a logical way, it is still a difficult problem.
The research team led by Xu Chuan needs to solve this difficult problem.
According to the strong electron-phonon interaction system in the strong electric unified theory, these days, they have manufactured a batch of magnetic monopole materials by controlling the reaction conditions and molecular structure, and made a test product with these magnetic monopole materials and conducted the first experiment.
The detailed experimental data is still being processed, but judging from the preliminary feedback from the computer, the expectation of this experiment may not be very good. The generated magnetic monopole field is not only not the magnetic field they want, but also may be extremely chaotic and difficult to stabilize.
This is also the reason why the disappointment on the faces of a group of people is greater than expectations.
Including Xu Chuan, he also frowned and flipped through the feedback data on the computer.
"Academician Xu, the complete and detailed experimental data has been printed out."
The door of the laboratory was hurriedly pushed open, and a researcher in a white coat walked in quickly, holding a thick stack of paper documents in his hands.
This was Li Kaichang, the researcher who was previously assigned to be responsible for the electromagnetic field of magnetic polaritons. After finishing the experiment, he couldn't wait and ran to the printer room in person.
A group of people quickly surrounded him. After Xu Chuan took the first stack of already divided experimental materials from it, the others rushed forward and divided up several copies of the materials printed at the same time by different printers.
"The situation is not optimistic."
Flipping through the experimental data in his hand, Xu Chuan sighed.
Li Kaichang, who had already read the detailed experimental data in advance in the printing room, nodded and smiled bitterly: "It's really not good."
What he didn't say was that this was not only not good, but it was terrible.
They used RbCI crystals to conduct a strong coupling polaron experiment, but judging from the data, the magnetic field strength was acceptable, but the magnetic flux, magnetic saturation, hysteresis, and magnetic polaritons were difficult to describe.
The hω (Mev) value of the magnetic polariton strength was only 10.2718, and the α (A°) value was only 1.92.
According to theory, the two data they designed should at least reach 30+ and 5+ to meet the basic requirements.
If this technology is to be applied to achieve plasma and electromagnetic deflection shields, the hω (Mev) of the magnetic polariton strength must reach 100+, and the α (A°) value must be 10+.
In other words, judging from the current experimental data, they are ten times away from real application.
Looking through the detailed experimental data in his hand, Xu Chuan looked at it and asked Li Kaichang, who was responsible for the research and development of magnetic polariton electromagnetic fields: "Do you have any ideas about these data?"
Li Kaichang frowned and thought for a while, then said with some hesitation: "Theoretically, the most direct correlation between the various indicators of the strong magnetic polariton electromagnetic field lies in the crystal material used to make it, whether it is an RbCI crystal. reason?"
Xu Chuan nodded and said: "There may indeed be some problems in materials, but RbCI crystal is almost the most suitable material choice we can find at present. We don't have many suitable choices among low-dimensional polarons."
After thinking for a moment, he continued: "Contact the Information Research Institute to model low-dimensional polaron materials through the strong electron-phonon interaction system and related experimental data to see if we can use supercomputing Let’s look for suitable materials.”
Li Kaichang nodded and said, "Okay, Academician Xu."
Xu Chuan thought for a while and said: "How is the situation of borrowing the large-scale SQUID superconducting quantum interference magnetometer from the Chinese Academy of Sciences?"
The SQUID superconducting quantum interference magnetometer is mainly used to detect DC magnetic susceptibility signals. There are many types of equipment of this type. Xinghai Research Institute has them, but not large ones.
It is probably too late to temporarily purchase and build such an experimental environment, so we can only borrow the laboratory space from the Chinese Academy of Sciences to make a more detailed judgment on the magnetic polariton field.
Li Kaichang: "The relevant application work is being carried out by Dean Wen Yuanhang. Dean Wen has given feedback before and has contacted the Chinese Academy of Sciences. The problem should not be big."
Just as he was talking, the door to the laboratory was pushed open, and Wen Yuanhang walked in while the two were chatting.
"Academician Xu, Team Leader Li."
After saying hello with a smile, he quickly said: "As for the application to borrow the large-scale SQUID superconducting quantum interference magnetometer test site from the Chinese Academy of Sciences, I have received a reply from the Chinese Academy of Sciences and the other party has agreed. .
After hearing these words, the frown on Xu Chuan's face finally relaxed a bit, and a smile appeared on his face.
Throwing the experimental data report in his hand on the table, he said: "That's it for today's experiment. Prepare the materials and equipment. Next, we will go to the Chinese Academy of Sciences to continue the experiment."
Li Kaichang nodded with a serious expression.
"yes!"
