Su Zhe followed Qian Sanduo out of the office building of the experimental center.

"Your University of Science and Technology is really powerful, it has a big scientific device like a synchrotron radiation light source independently, and the teachers and students of your school are so happy that they don't have to go to Shencheng and Yanjing to queue up for relevant experiments." Walking on the road, Su Zhe said with some surprise.

In China, there are only three synchrotron radiation devices in existence and operation, which are located in Yanjing, Shencheng, and Badu.

Badu's synchrotron radiation device is the most special, owned by HKUST.

"Happiness is a blessing, but the cost of construction and maintenance is not a small amount." Qian Sanduo sighed, "Just two years ago, it cost 800 million, for this money, my teacher doesn't know how many people I begged, pitiful!" ”

Badu synchrotron radiation device is the second generation of synchrotron radiation light source, not to mention that it cannot produce hard X-ray light sources, but also consumes special energy.

After the third-generation synchrotron radiation light sources in Yanjing and Shencheng were put into use, fewer people applied for their use, and their income naturally decreased.

The maintainable funds are still required, and the use of teachers and students in the school can only be maintained by the school.

When the synchrotron radiation experimental center was about to become unsustainable, the school committee unanimously decided to let his teacher Huang Weicai take over the position of director.

You must know that whether it is the director or the deputy director, in the past, it was only an academician who could do it, but I didn't expect it to fall on the head of his teacher, a full professor.

Having said that, his teacher Huang Weicai is also ruthless, and after taking over the synchrotron radiation experimental center, the first thing he did was to upgrade.

The school provides a fund of 100 million, and the total cost of upgrading is 800 million, a difference of 700 million.

His teacher asked Bao Zhengyi, a rich second-generation junior brother, for a sponsorship of 100 million, and the other 600 million was asked by his teacher from one company to another.

As a participant in the whole process, he is well aware of the difficulties of his teachers.

He was embarrassed to say these to Su Zhe.

Su Zhe looked at Qian Sanduo, who was depressed, and didn't speak anymore, but thought about it in his heart.

Whether it is the ZDY-impact atomic model or the ZGZ-atomic vibration model, a large number of experiments are required.

The former requires electrons from the low-energy region to the high-energy region, and the latter requires a tunable light source from far-infrared light to hard X-rays.

He thought that the synchrotron radiation light source would be the most suitable.

The semi-abandoned positron collider of Lingzhou Institute of Technology can still be renovated.

……

The two of them walked some distance to a large circular structure with a long tail.

"In front of me is the main part of the synchrotron radiation experimental center, and if you look down from the air, the experimental center looks like a tennis racket." Qian Sanduo said with some pride.

"It's spectacular!" Su Zhe sighed.

"You see that the straight part is 110 meters long, which is an electron linear accelerator, the large annular part is the main electron storage ring of the synchrotron radiation device, with a circumference of 420 meters, and there is also an intensifier with a circumference of 160 meters in the large ring, and on the periphery of the large ring is the synchrotron radiation beam station and the experimental station." Qian Sanduo explained, "Actually! Both the electron storage ring and the intensifier are ring-shaped electron accelerators, and in the beginning, the electrons are in the ......"

Qian Sanduo explained in detail the working principle of the synchrotron radiation device, and Su Zhe listened carefully.

The electrons are initially accelerated in the electron linear accelerator, then enter the enhancement in which they are further accelerated, and finally enter the closed loop of electron storage.

In the electron storage ring, synchrotron radiation light is emitted when electrons moving at high speed are deflected by a magnetic field.

The synchrotron radiation light is introduced into the beam station, where it is reprocessed according to the user's requirements, such as collimation and focusing, and then transported to the user's experimental station.

"Su Zhe! You've come up with high-precision optical lenses, which has been a huge help to us. Qian Sanduo said with a smile, "The higher the accuracy of the optical lens, the purer the monochromatic light we can parse...... Let's go, let's go in. ”

Coming to the entrance hall, Qian Sanduo swiped the access control with a card.

The two then put on button-sized radiation dosimeters.

"Su Zhe! The interior of the experimental center and the experimental station were not easy to visit, so we had to look along the surrounding passages. Qian Sanduo explained.

"Understood!" Su Zhe nodded.

He is not stupid either, now the synchrotron radiation device is in operation, and the entry of people inside is prohibited.

The experimental station is doing experiments and tests, and you are a stranger to visit it!

Su Zhe followed Qian Sanduo into the elevator, Qian Sanduo pressed three floors, and when he came out, there was a platform, and on both sides of the platform were passages.

Both the platform and the passage are separated from the main body by tempered glass.

He made his way to the edge of the platform and saw the busy researchers on the ground.

Looking at the ground, he estimated that the platform was fifteen meters above the ground.

"Su Zhe! The experimental station you see now is the No. 1 experimental station, and these people are doing three-dimensional analysis of biological macromolecules, the relationship between research institutions and functions. Qian Sanduo said, "Some people often say on the Internet that the synchrotron radiation device is a super microscope, and what they say is also reasonable." ”

"I've seen the video of the introduction." Su Zhe smiled and nodded.

"Let's go! Let's go around in circles. Qian Sanduo walked into the visiting channel, "At present, there are eight experimental stations in our experimental center, seven of which are in use, and one is idle, just so you want to use it." ”

Su Zhe followed behind and listened to Qian Sanduo's explanation.

"Of the seven experimental stations in use, three are used for external fees, and four are used by our school itself, so that we can just break even." Qian Sanduo said with a smile, "This time, Professor Bao Zhengyi Bao is generous enough, worthy of the rich second generation, and directly gave 20 million yuan for the use of the fee, excluding the renovation fee of the experimental station, our experimental center made a net profit of 18 million." ”

Su Zhe listened and watched, and found that there were really a lot of people in the No. 2 experimental station, roughly estimated that there were more than fifty people, and many of them still had small notebooks in their hands.

Seeing this, he asked puzzledly: "Why are there so many people in this No. 2 experimental station, I feel that these people are not here to do experiments, but like they are studying." ”

"You guessed it, these are undergraduates from various colleges and universities who are here for the summer camp." Qian Sanduo explained, "Look, the No. 3 experimental station is made of materials, the No. 4 experimental station is made of medicine, and the No. 5 experimental station is idle, which will be used for you after the transformation, and will be ...... later."

Su Zhe watched while listening to Qian Sanduo's explanation.

Soon, the two went around in a circle and returned to the platform where they started.

After reading this, Su Zhe was a little yearning, he wanted such a big scientific device.

He thought for a moment and asked Qian Sanduo, "How much does it cost to build such a synchrotron radiation device now?" ”

"Ah......" Qian Sanduo was a little surprised, "If you build it now, it will cost at least 1600 million, this is the third-generation synchrotron radiation light source, like the fourth-generation synchrotron radiation light source that Yanjing is building, the construction cost alone is as high as 300 million." ”

"Expensive enough." When Su Zhe spoke, he noticed that Qian Sanduo was looking at his phone, and he had looked at it several times at this moment.

"Of course, big science devices cost money, and that's a drizzle compared to the Large Hadron Collider." Qian Sanduo put his phone in his pocket a little anxiously.

"Is there anything wrong with you? You don't have to accompany me. Su Zhe reminded.

"Well, there's a lecture in lecture hall No. 3 in the library at seven o'clock in the evening, I want to listen to it, do you want to join us?" Qian Sanduo said embarrassedly.

It's already half past six, and with the time it takes to walk past, you'll miss the start time.
