In the auditorium, the applause was deafening.

Liu Feng withdrew amid applause, and was interviewed by the media at the door of the auditorium.

After he was interviewed by the media, Principal Xue Hongyun walked over to him with several school leaders and professors.

With a warm smile on his face, Principal Xue stepped forward and shook hands with Liu Feng and said, "Thank you Professor Liu for this vivid speech to our school!"

After hearing this, a few students who walked by couldn't help but feel a pain in their eggs, from the beginning to the end of this lecture, they didn't feel anything vivid at all!

Liu Feng smiled and said modestly: "Where is it, it's just that some of my understanding of the grand unified theory and dark matter antimatter is still too boring." ”

At this time, standing next to him, an old professor smiled and said: "Where is it boring? I listen to it with relish! If you want to count the research on dark matter and antimatter in China, who can have such a level as you? You have benefited a lot, you have benefited a lot!"

Liu Feng shook his head embarrassedly: "It's too famous, you are Academician Tian Xuelin Tian, right? Hello, hello, I have admired my name for a long time." ”

"Hello, hello," holding Liu Feng's hand and shaking it, Academician Tian Xuelin said with a smile, "I have long heard that Professor Liu Feng is young and promising, but I didn't expect it to be even younger than I imagined!

Liu Feng smiled and said, "Tian Lao, you are joking, with your current age, you can continue to work for at least 30 years!"

"Haha, it's a joke, if you continue to work for 30 years, you won't be old and immortal!" Academician Tian joked with a smile.

The retirement age of academicians of the Chinese Academy of Sciences is generally around 70 years old, but it usually depends on the individual, and if you feel that you can't do it anymore, you can naturally apply for retirement. Seeing that he is about to turn 70 years old this year, he can still work for another 5 years at most, 30 years?

Shook his head.

The two of them talked and laughed as they walked towards the office next door.

Originally, President Xue planned to bring the team of school leaders to come with him, but Liu Feng politely declined his proposal on the grounds that he "didn't want to disturb the daily work of Sichuan University".

If you don't keep it secret, you will lose your minister.

The antimatter project was still only in his mind, both professionally and confidentially, and there were too many laymen to follow him, and it was not convenient to talk about many things.

Following Academician Tian Xuelin to the nuclear physics laboratory, Liu Feng briefly turned around under his leadership, chatting about the Great Unified Theory and the recent big moves in the field of high-energy physics abroad, and chatting about the domestic super collider project.

When it came to the super collider project, Academician Tian Xuelin's face was full of emotion.

"After more than 10 years of argumentation, we finally have our own super collider in China! Alas, the old director Quanxia has knowledge, and he can also turn a blind eye. ”

The old dean in the mouth of Academician Tian Xuelin is Academician Hu Jimin, the former director of the Institute of High Energy. The Beijing Positron Collider was built during his tenure, and Academician Tian Xuelin was a student of his old man at the beginning, but it is a pity that the old academician has passed away for nearly 10 years.

Liu Feng also nodded: "Yes, Academician Hu didn't know how much effort he put into the Super Collider project, but he didn't have a holiday." ”

Academician Tian shook his head: "Forget it, don't talk about this." Thanks to your grand unified theory, a new particle has been discovered over there, outside the scope of the Standard Model, and the existence of the Higgs dice has also been confirmed by the people of country M; according to the timetable of these people, in the next 20 years, they will conduct systematic research on supersymmetric particles, dark matter and antimatter, if nothing else, around 2030, there will be explosive technological breakthroughs in high-energy physics, fortunately our country has launched the super collider project, otherwise, the gap will be wider and wider. ”

Liu Feng nodded in agreement: "It is precisely because the country has seen this that it has increased its investment in high-energy physics." ”

Academician Tian Xuelin shook his head and sighed a little: "Yes! It's a pity that I'm already old, and I can't follow in your footsteps, and I can't see that day!"

"Where, the country and the people are still looking forward to you continuing to shine!"

The two quickly walked around the laboratory and came to Academician Tian's office.

Professor Tian instructed his students to pour two glasses of water, and Liu Feng was also a little thirsty, so he drank a glass and sat down on the sofa.

"Tian Lao, I haven't had the opportunity to visit you, speaking of which, I have a few questions about the "Pengning Ion Trap" when I came to Sichuan University this time, such as asking you, you are an expert in this area, I don't know if it's convenient?"

Tian Lao also drank the water, and then instructed the students to fill the water, smiled and said, "Don't be so polite, you ask." ”

Nodding, Liu Feng's face was solemn, and he said seriously: "In an ideal Pengning ion trap, the hyperboloid of the ring and the end rotation stretched, in the case of capturing positive (negative) ions, the end electrode is maintained at a positive (negative) potential relative to the ring, and this potential produces a "saddle point" when the potential well is generated, so this confines the ions to the center of the axis. ”

Therefore, most of the world's laboratories now rely on this method to constrain the dotted particles, but what if it is an antimatter particle? The electric field causes the ions to oscillate continuously when they move in the axial center, and the magnetic field used in conjunction with the electric field causes the charged particles to draw an outer rotor line in the radial plane motion, resulting in the "waiting zone" of the Penning ion trap There will always be a lot of lost matter particles, and when the two come into contact, there will definitely be a large-scale annihilation reaction, resulting in the antimatter particles are very unstable and easy to be knocked out of this axis, do you have any good solutions to solve it?"

After hearing this question, Tian Lao frowned, thought for a moment, and then spoke.

"I don't do much research on antimatter, I heard that the people of country M seem to have developed a solution to this problem, and when I was in the PPPL laboratory, I also saw similar research, but it was not successful. ”

"Yes, those papers were sent to the Physics Letters, and according to the content of the papers, the methods they used were basically to increase the strength of the electromagnetic field, but unfortunately the effect was not very good, and a lot of lost particles were still produced in the vacuum region. ”

Liu Feng continued.

Tian Lao nodded: "I don't know how the people of country M relied on the "Penning Ion Trap" to store antimatter particles for a few months, but maybe we can think differently......

Listening to the old man's answer, Liu Feng nodded thoughtfully.

Although Tian Lao did not have any research on the storage of antimatter, relying on decades of deep accumulation in the "Pengning ion trap" technology, the old man still proposed two solutions for him.

Although these two ideas still need to be verified by specific experiments, for Liu Feng, it is also a kind of enlightenment.

It is said that if there is an old man in the family, if there is a treasure, the ancients did not deceive me.

The harvest was full, and Liu Feng couldn't wait to return to the capital immediately and personally test these two solutions.

Seeing this, Tian Lao smiled and said in a relaxed tone: "Is there any more problem?"

"Thank you, Professor Tian, no. ”

Tian Lao nodded: "I also have a few questions I want to ask you......

Seizing this rare opportunity, Professor Tian also consulted Liu Feng on all the theoretical problems he encountered in his research.

As for the parts of these questions that he can answer, Liu Feng also answered them one by one.

As the minutes ticked by, the two sat in the office for almost two hours.

Glancing at the time, Academician Tian said embarrassedly: "I'm sorry, Professor Liu, I've delayed you for so long." ”

Liu Feng smiled indifferently: "Where, I also delayed you so much." What's more, I have learned a lot from communicating with you. ”

Academician Tian nodded, and suddenly said meaningfully: "Speaking of which, you have asked so many difficult questions about the constraints of the antimatter "Penning ion trap", the next step should not be to study antimatter, right?"

Looking at Academician Tian's smile like an old fox, Liu Feng sighed, thinking that he still couldn't hide such an old fox.

After a pause, he finally threw out an olive branch: "Academician Tian, if you are always in charge of researching the storage of antimatter, I don't know if you are interested?" 8)
