Su Zhe followed Qian Sanduo out of the experimental center office building.
"Your University of Science and Technology is really powerful. It actually owns a large scientific device like the synchrotron radiation light source. The teachers and students of your school are so lucky. They don't have to queue up in Shanghai and Yanjing to do relevant experiments." Su Zhe walked on the road. Said with some surprise.
There are only three synchrotron radiation devices currently in operation in China, located in Yanjing, Shanghai, and Badu.
The synchrotron radiation facility in Badu is the most special and is owned by HKUST.
"Happiness is a blessing, but the construction and maintenance costs are not small." Qian Sanduo sighed, "The upgrade two years ago cost a total of 800 million. For this money, my teacher asked countless people for help. Poor ah!"
The Badu Synchrotron Radiation Facility is a second-generation synchrotron radiation light source. Not only can it not produce hard X-ray light sources, it also consumes a lot of energy.
After the third-generation synchrotron radiation light sources in Yanjing and Shencheng were put into use, fewer people applied to use them, and their income naturally decreased.
Maintenance funds are still needed, and coupled with the use of teachers and students on campus, the school can only subsidize money to maintain it.
When the Synchrotron Radiation Experiment Center was about to be unable to survive, the school committee unanimously decided to let his teacher Huang Weicai take over the position of director.
You know, whether it is the director or the deputy director, they could only be done by academicians in the past, but I didn't expect that it would fall to his teacher, a full professor.
Having said that, his teacher Huang Weicai was also ruthless. After taking over the Synchrotron Radiation Experiment Center, the first thing he did was upgrade.
The school provided 100 million in funds, and the total upgrade cost was 800 million, a difference of 700 million.
His teacher asked his second-generation rich junior brother Bao Zhengyi for a sponsorship of 100 million, and the other 600 million came from his teacher's company one company after another.
As a full participant, he knows how difficult it is for his teacher.
He was embarrassed to tell Su Zhe all this.
Su Zhe looked at Qian Sanduo who was in a low mood and said nothing more, but was thinking in his mind.
Whether it is the ZDY-impact atomic model or the ZGZ-atomic vibration model, a lot of experiments are required.
The former requires electrons from a low-energy region to a high-energy region, and the latter requires a tunable light source from far-infrared light to hard X-rays.
He thought long and hard about whether a synchrotron radiation source would be the most suitable.
Lingzhou Institute of Technology's semi-abandoned electron-positron collider can still be renovated.
…
The two walked a certain distance and came to a huge ring-shaped building with a long tail.
"What is in front of us is the main part of the synchrotron radiation experimental center. If you look down from the air, the experimental center looks like a tennis racket." Qian Sanduo said with some pride.
"It's so spectacular!" Su Zhe sighed.
"You see that the straight part is 110 meters long and is the electron linear accelerator. The large ring-shaped part is the main electron storage ring of the synchrotron radiation device. It has a circumference of 420 meters. There is also a circumference inside the large ring. The 160-meter-long intensifier has a synchrotron radiation beam station and an experimental station on the periphery of the large ring." Qian Sanduo explained, "Actually! The electron storage ring and the intensifier are both ring-shaped electron accelerators. At the beginning, the electrons exist……"
Qian Sanduo explained the working principle of the synchrotron radiation device in detail, and Su Zhe listened carefully.
The electrons are initially accelerated in the electron linear accelerator, then enter the enhanced accelerator for further acceleration, and finally enter the closed-loop electron storage ring.
In the electron storage ring, synchrotron radiation is released when high-speed electrons are deflected by a magnetic field.
The synchrotron radiation light is introduced into the beam station, where it is collimated and focused according to user requirements, and then transported to the user experiment station.
"Su Zhe! The high-precision optical lens you have developed is of great help to us." Qian Sanduo said with a smile, "The higher the precision of the optical lens, the more pure monochromatic light we can analyze... , let’s go in.”
Arriving at the entrance hall, Qian Sanduo swiped the access control with his card.
The pair then wore button-sized radiation dosimeters.
"Su Zhe! It is not convenient to visit the interior of the experimental center and the experimental station. We can only take a look along the surrounding visiting passages." Qian Sanduo explained.
"Understood!" Su Zhe nodded.
He is not stupid either. The synchrotron radiation device is currently in operation and no one is allowed to enter inside.
The experimental station is conducting experiments and tests. What's wrong with you, a stranger, coming in to visit?
Su Zhe followed Qian Sanduo into the elevator. Qian Sanduo pressed the button for the third floor. When he came out, there was a platform with passages on both sides of the platform.
Both the platform and the passage are separated from the main body by tempered glass.
He came 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 Experiment Station No. 1. These people are doing three-dimensional analysis of biological macromolecules and studying the relationship between organization and function." Qian Sanduo said, "Some people often say on the Internet that synchrotron radiation The device is a super microscope, which makes sense.”
"I've seen the introduction video." Su Zhe nodded with a smile.
"Let's go! Let's go around." Qian Sanduo walked into the visiting passage, "Currently, our experimental center has eight experimental stations, seven of which are in use, and one is idle, which you just want to use."
Su Zhe followed behind and listened to Qian Sanduo's explanation.
"Of the seven experimental stations in use, three are for external use and four are for our school's own use, so we can just break even." Qian Sanduo said with a smile, "Professor Bao Zhengyi and Bao are generous this time, and I am worthy of it." He is the second generation of rich people and directly paid 20 million in usage fees. Excluding the renovation costs of the experimental station, our experimental center made a net profit of 18 million."
Su Zhe listened and looked, and found that there were quite a lot of people at Experiment Station No. 2. It was roughly estimated that there were more than fifty people, and many of them had small notebooks in their hands.
Seeing this, he asked in confusion: "Why are there so many people in Experiment Station No. 2? It feels like these people are not here to do experiments, but rather to study."
"You guessed it right, these are undergraduate students from various universities who came to participate in the summer camp." Qian Sanduo explained, "Look, the No. 3 Experiment Station is making materials, the No. 4 Experiment Station is making medicine, and the No. 5 Experiment Station is making medicine. It's unused and will be renovated for you to use later..."
Su Zhe watched and listened to Qian Sanduo's explanation.
Soon, the two of them turned around and returned to the starting platform.
After reading this, Su Zhe felt a little yearning. He wanted such a big scientific device.
He thought for a while 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 we build it now, it will cost at least 1.6 billion. This is the third generation synchrotron radiation light source. Like the fourth generation synchrotron radiation light source being built in Yanjing, the construction cost alone is as high as Three billion."
"It's expensive enough." When Su Zhe said, he noticed Qian Sanduo looking at his mobile phone. He had looked at it several times in this moment.
"Of course, big scientific equipment costs money. Compared with the Large Hadron Collider, this is just drizzle." Qian Sanduo put his cell phone in his pocket anxiously.
"What's the matter with you? You don't need to accompany me." Su Zhe reminded.
"Well, there is a lecture in Lecture Hall No. 3 of the library at seven o'clock in the evening. I want to go to it. Do you want to come with me?" Qian Sanduo said awkwardly.
It's already half past six, and if you take the time to walk over, you'll miss the start time.
