Yang Jie then came to another user control room, and saw that Victor and others were also doing experiments, and Victor and others were working on a new catalyst for fuel cells.

They used scanning tunneling microscopy and X-ray photoelectron spectroscopy of ambient pressure to study the structure and composition of the catalyst according to the actual conditions.

Yang Jie also chatted with everyone about technical things for a while before leaving.

After inspecting the seven line stations, the time also came to more than 10 o'clock in the evening.

When Yang Jie was about to go to a nearby residential area to rest, Chen Fangtong, the leader of the Yanjing Municipal Party Committee, also hurried over.

The somewhat depressed man's face was red at this time, and he could smell the smell of alcohol from a distance.

"Oh, Yang Shao, I was entertaining the representatives of South Korea in the evening, and when I heard you coming, I slipped away halfway, and I didn't have time to greet you, I'm really sorry!"

Chen Fangtong held Yang Jie's hand and said loudly.

"I also rushed back on a temporary basis, I also finished seeing this laboratory just now, and I will visit you tomorrow. ”

Yang Jie said with a smile.

"Yang Shao is also rare to come, I should come to talk to you. ”

Chen Fangtong said with a smile, paused and asked, "Where is Yang Shao going?"

"I'm going to rest in the residential area here, why don't you go there and have a cup of tea together?"

"That's a good idea!"

Chen Fangtong said with a smile.

When going to the nearby residential area, Chen Fangtong also said with emotion: "I didn't expect this large-scale laboratory of divine light source to be built so quickly, faster than these countries in Europe. ”

"We have to be fast, we have a lot of experiments to do in Huaxing Group, and it would be too much time to go to the laboratory over there to do experiments. ”

"Yes, not only Huaxing Group has a large number of experiments, but also many domestic scientific research institutions have a lot of experiments to do, and a very critical large-scale laboratory like this is too important......"

Chen Fangtong nodded and said: "The construction of this light source facility in Jinshan City has been delayed for a long time, so it's no wonder that Yang Shao wants to start anew." ”

The Jinshan City Light Source Project is a project led by Xu Kunlin, the former mayor of Jinshan City, but there has always been a dispute between him and Geng Jianbiao, and the latter has been pressing the project out of personal grievances over the years as the mayor of Jinshan City and the leader of the municipal party committee.

And since he joined the Standing Committee, he has not said a lot of bad things about Huaxing Group and secretly engaged in sabotage, but Huaxing Group has always been operating legally, and the customers are mainly consumers and enterprises, plus the communication between Huaxing Group and these central bigwigs is still very smooth, but it did not let this person do anything bad.

Yang Jie smiled, he didn't want to expand on this topic, and said: "For this matter, Chief Li Kaiyuan has criticized me, and whether Shenguang Light Source Co., Ltd. can succeed in the future depends on your support!"

"Haha, Yang Shao, please put a hundred hearts, I must make this science park and innovation zone successful, and I will not allow others to obstruct and interfere casually. ”

Chen Fangtong said with a firm face: "To be honest, if I just want political achievements, I can hand over a beautiful report card by pulling some projects, but I think the third-generation synchrotron radiation light source is the big scientific device that Yanjing City needs the most." ”

"Although there is now a large positron collider in Yanjing City, a large scientific device, but this large scientific device for so many years has actually produced limited scientific and technological achievements, to the 60s of the last century, physicists have discovered more than 100 kinds of particles, so many years, scientists in this area of research progress is too slow, many are conjectures, can not be verified by such a device. ”

At this stage, scientists cannot observe the real situation inside the nucleus, and they can only use a collider to break up the electrons by impacting and crushing these electrons, and then use special instruments to record the energy spectrum of the particles inside to discover the particles.

It's just that these particles are unstable particles, and most of them are fleeting, and they are extremely difficult to observe, record, and describe, let alone capture and preserve.

At the same time, new particles will be produced before and after the collision, and they are all unstable particles, in short, after the collision, all the particles left behind are conventional stable particles or particles with unstable half-lives, which is meaningless for research.

Even if a new particle is found by luck, it can only be a supplement to the original physical theoretical model based on the new particle, and scientists still do not understand what the interaction between these particles is, so they can only make some conjectures, and these conjectures need to be constantly collided to verify.

Because scientists did not have the means to visually observe the inside of these electrons, the construction of the collider facility can be said to be one of the means.

At the same time, scientists continue to develop light sources for observing molecules and atoms, with the aim of figuring out what's going on inside molecules and atoms.

Scientists are now working the fourth generation of light sources, known as X-ray lasers.

In the memory of Yang Jie's previous life, this light source was the first to be created by Eagle Sauce, and it was also in April 2009 that Eagle Sauce's linear accelerator coherent light source was born at the National Accelerator Laboratory in California.

The 130-meter-long giant laser accelerates electron energy from 4.3 geV to 136 geV by the last kilometer of a 2-mile-long linear accelerator, taking 2 hours to start the device each time. The plant took three years to complete, and it took almost 10 years from the time the plan was proposed to the completion of the preparations.

It is also the world's first free electron laser that emits hard X-rays, with an output wavelength tunable between 0.15~1.5 nanometers, and each pulse contains 10 trillion X-ray photons.

With this powerful tool, scientists can use it not only to solve the mystery of the atomic structure of viruses and cells, but also to create three-dimensional images of nanoparticles, record chemical reactions, and observe the reaction processes inside the particles.

With this device, scientists can see what happens after the electron collides, which is a more advanced tool for basic physics research.

The third-generation light source can clearly "see" the molecules, atomic appearances and chemical bonds, while the fourth-generation light source can "see" the activities of various particles inside the atoms very clearly, which is of absolute significance for thoroughly understanding the laws of the universe.

This is also a super tool that scientists dream of, and it is of great practical significance for various technical fields.

Although Yanjing had a large scientific device such as the Positron Collider in the 80s, it also provided a synchrotron radiation light source, which operated in a special mode for synchrotron radiation part of the time, and the overall performance in the special mode roughly reached the level of the second-generation light source.

In addition, the National Synchrotron Radiation National Laboratory light source facility at the University of Science and Technology can only provide second-generation light sources.

Yang Jie's investment in the construction of this set of light source facilities can provide extreme ultraviolet light source, which is already very close to the X-ray wavelength, which can be regarded as a soft X-ray laser light source, which is only one step away from the fourth generation light source, and can also be regarded as the fourth generation light source, which is the most advanced light source in China at this stage.

Chen Fangtong naturally attaches great importance to this.
