Sangyeong University, Optical Lens Research Center, Ion Beam Polishing Technology Research Laboratory.
Su Zhe listened carefully to Bao Zhengyi's explanation.
Bao Zhengyi introduced the ion beam generator in detail and talked about the material composition of the ion beam.
From the generation of ions to acceleration, clustering, focusing, and finally projection to the processing part of the workpiece surface, the atoms or molecules on the workpiece surface are impacted out to achieve ion polishing.
Different ions, different energy obtained by ion acceleration, different angles of the projected workpiece surface, etc. will all lead to different results.
Then there is the material composition of the workpiece itself, that is, the lens of the optical lens being processed, which will also affect the final processing accuracy.
"In order to better analyze the processing process and grasp the underlying principles behind the technology, we installed full-band electromagnetic wave receivers, particle detectors, etc. around the ion beam polishing equipment. You see, these X-rays also detect Calcium atoms." Bao Zhengyi pointed at a screen and said.
Su Zhe looked at the waveforms and other information on the display carefully. The slope length of this X-ray was 1.25 nanometers, and he unconsciously combined the known relevant information in his mind.
For example, the material composition of optical lens lenses for processing workpieces is mainly silicon dioxide, with a small amount of calcium hydroxide, boron oxide, etc. added.
The material composition of the ion beam, the energy obtained by acceleration, the angle of incidence, etc.
Plus the environment in which the entire processing process takes place.
He was calculating quickly in his mind.
"Xiao Zhe! Why are you sweating on your forehead?" Bao Zhengyi turned his head and noticed the fine sweat on Su Zhe's forehead.
"Ah!" Su Zhe stopped calculating and raised his hand to wipe the sweat from his forehead.
We don’t know enough data to make any calculations.
"Xiao Zhe! Do you know which group this X-ray was generated from?" Bao Zhengyi asked tentatively.
Su Zhe turned his head and looked at the two circular windows and replied: "X-rays are produced by that group of negatively charged ion beams."
"You guessed it right, then do you know how these X-rays are generated?" After Bao Zhengyi finished speaking, he felt that he shouldn't ask this question because he was trying to make things difficult for others. After all, Su Zhe just graduated from high school.
He turned to look at Fan Xiaoming so that Fan Xiaoming could help Su Zhe. Just as Fan Xiaoming was about to speak, Su Zhe spoke.
"There are free high-energy electrons in the negatively charged ion beam. The high-energy electrons bombard the calcium in the workpiece. The electron layer of calcium absorbs the energy of the high-energy electrons. The electrons of the calcium atoms jump from the low-energy electron layer to the high-energy electron layer. At this time The electrons in the high-energy electron layer are in an excited state, and in a very short period of time, the electrons in the excited state transition to a low-energy electron layer, and the excess energy is spread out in the form of X-rays."
The more Bao Zhengyi listened, the more delighted he became. Knowing this meant that Su Zhe had learned very solid knowledge in high school and had done in-depth research. When he saw Su Zhe stop, he planned to praise Su Zhe, but he knew that Su Zhe stood He got up and continued speaking, which surprised him.
"There are oxygen atoms, silicon atoms, boron atoms, hydrogen atoms, calcium atoms, etc. in the workpiece being processed. The reason why I determined that X-rays are produced by calcium atoms bombarded by high-energy electrons is because of the wavelength of X-rays. Through calculation... "
Su Zhe talked about the energy levels of each electron layer of calcium atoms, estimated the energy carried by high-energy electrons, and calculated step by step. Finally, he calculated the frequency of X-rays. If you know the frequency, you will naturally know the wavelength.
Following Su Zhe's calculation, Bao Zhengyi and Fan Xiaoming opened their mouths.
Su Zhe reported a set of data, and the two opened their mouths wider.
Other people in the laboratory also gathered around, and these people also looked surprised.
From the conversation between the three of them, they knew that Su Zhe was a newly graduated high school student.
But with his current performance, no one could believe that the person standing in front of him was a high school student.
A lot of them can't do that.
After Su Zhe stopped speaking, after a while, Bao Zhengyi and Fan Xiaoming stood up.
"Xiao Zhe! Where did you learn this... from listening to lectures? That shouldn't be the case. Shangling University basically doesn't have such courses." Fan Xiaoming asked with a surprised look on his face.
"I taught myself." Su Zhe replied calmly.
"That's right, geniuses! They are all self-taught." Seeing everyone gathered around, Bao Zhengyi said with a smile, "Since everyone has gathered around, let me introduce to you, this is the South Gate of our city. A senior high school graduate from Nanmen No. 1 Middle School in the county took the college entrance examination this year and scored 100 in mathematics... That Su Zhe is the seeded winner of this year's top scorer in science."
He almost let it slip that Su Zhe's score of 150 on the math test couldn't be told outside. He almost hurt his lover.
He was not surprised at all by the knowledge Su Zhe had mastered. He was a genius! It's normal to know this.
After he finished speaking, everyone applauded and said at the same time.
"It's no wonder. It's not surprising that he is a super academic."
"I remembered. I saw that short video. It said that mathematics is not difficult and students can get 150 points. It turned out to be true."
"Geniuses are indeed no ordinary people."
…
Seeing that the applause had stopped, Bao Zhengyi coughed and said: "It's not too late today. Those who should go back to sleep should go back to sleep. Keep busy. The next three days are the most critical three days. If everyone just persists, we will soon be there." We can see the light of day, come on!"
"come on!"
Everyone dispersed, some people packed up and left the laboratory, and some people continued to stay at their workstations.
Bao Zhengyi looked at Su Zhe and said with a smile: "Xiao Zhe! You surprised me so much... You study hard during this period of time in the research center. When Xiaoming and I finish these three days, what do you want to learn? We will teach you. In these three days, you can get familiar with the R&D center and do other things. I don’t impose any requirements on you. You are a genius! You are all self-taught."
"Thank you, Professor Bao." Su Zhe said sincerely.
He originally wanted to continue saying that if Bao Zhengyi knew his true level, he could participate in the research and development of ion beam polishing technology, but Professor Bao said so and could only wait three days.
Bao Zhengyi nodded, looked at the time, turned to Fan Xiaoming, and said, "Take Su Zhe back to rest! It's already half past ten at night."
After saying hello, Su Zhe and Fan Xiaoming left the ion beam polishing technology research laboratory.
On the way to the office, Fan Xiaoming said listlessly: "The next three days are the busiest for us during this period. We have to stay in the laboratory 24 hours a day. We don't know the results of this time, which is the sixth time." What will happen? If it doesn’t work, the two months of work will be in vain.”
"The sixth time?" Su Zhe asked.
"Yes! It has failed five times before." Fan Xiaoming was a little disappointed. "By the way, when you get to the office, I will teach you how to use the data system of the R&D center. You can familiarize yourself with it in the past three days."
"Well... okay!" Su Zhe originally wanted to say that he participated in the development of the Guanxue lens, but thinking that this was the last three days of testing, he stopped talking.
Participating at this time will cause trouble.
When he came to the office, Su Zhe used his campus card number to log in to the optical lens research center data system. With Fan Xiaoming's prompts, he quickly learned to use it.
Afterwards, the two of them went to the cafeteria and had supper. It was already twelve o'clock when they returned to the dormitory. After washing, they went back to their rooms to sleep.
