Su Zhe took out his mobile phone, and it was a video call from Fan Xiaoming.

After connecting, Fan Xiaoming asked him where he was? Let him go to lecture hall 1, the technical presentation will start soon.

After hanging up the video call, he swiped his card and got off the plane.

Take his cloth tote bag and head to Lecture Hall One.

According to Fan Xiaoming, the technical report will introduce related technologies, mainly to introduce the application of related technologies.

In layman's terms, it's a show.

……

Lecture Hall No. 1 on the fourth floor of the library.

Niu Guanghui looked at the more than 100 good people attending the meeting, and felt a little uneasy.

Before coming, the teacher warned him and asked him to help Senior Brother Bao check it, but Senior Brother Bao was good, no matter how he asked, Senior Brother Bao would say two perfunctory sentences at most.

"Don't worry! We have really broken through the ion beam polishing technology, and it is definitely not an oolong. ”

It is not allowed to let him see the inspection data of the processed lens, let alone the process of the breakthrough of ion beam polishing technology.

Uneasy, he pulled his junior brother Bao Zhengyi to the side.

"Senior Brother Bao! The technical report will start soon, and you can honestly say that the ion beam polishing technology is not really a breakthrough, but you have just failed the sixth test, and I am worried about ......"

"Professor Niu! Do you think I'm stupid? Bao Zhengyi asked with a smile.

"Not stupid! But in terms of time...... It's too fast. Niu Guanghui said bluntly.

"It's a little faster, but the DYN-ion beam polishing technique is completely feasible, and you know, we didn't test one group, but two, and the results were exceptionally good." Bao Zhengyi replied with a smile.

"Two groups! The results of the test are the same as in the invitation letter, and the mirror surface has reached the peak and valley value of 0.09 nanometers of surface accuracy and the surface roughness of 19 picometers? Niu Guanghui smiled.

At first, he was not worried that Bao Zhengyi was fake, but that the results of the lenses tested in the invitation letter were just an isolated case, and that it was just a coincidence.

The two groups are different.

"Almost! I won't say much about it now, and I'll talk about it in a moment. Bao Zhengyi smiled, "Senior brother! This report will definitely surprise you. ”

"Surprise! What's the surprise? Could it be that the plasma EUV light source has broken through. Si Wenbo came up with a smile, "By the way, I just heard that this DYN-ion beam polishing technology is related to Su Zhe, is it true?" ”

Su Zhecai graduated from high school and came to Shangling University to study, how could it be related to DYN-ion beam polishing technology?

He was puzzled.

"DYN-ion beam polishing technology is related to Su Zhe, how can it be?" Niu Guanghui looked surprised.

"It's related, you'll find out in a moment." Bao Zhengyi said and looked at Si Wenbo, "Congratulations!" Professor Si, with the optical lens, the synchrotron radiation EUV light source you have made can be used in the EUV lithography machine, which is really gratifying. ”

"Rejoice and rejoice!" Si Wenbo laughed for a while, and his face became serious again, "To be honest, I really hope that the plasma EUV light source researched by Professor Niu can break through, after all, the synchrotron radiation EUV light source we made is too energy-intensive, and even if we build an EUV lithography machine, it is not competitive in the world." ”

Although he and Niu Guanghui are competitors, when the synchrotron radiation EUV light source project was established, he knew that the project he did was just a backup, just to cope with the current situation.

He knew very well in his heart that everyone wanted to see a breakthrough in plasma EUV light sources.

Hearing this, Bao Zhengyi and Niu Guanghui looked at each other and looked at Si Wenbo with some surprise.

"What? You don't think that I still think about my own interests in the face of major problems! Underestimate me. Si Wenbo said a little smugly, "I said Lao Niu! Tell me about your problems and see if I can give you some advice. ”

"This ...... All right! We sat back and said. Niu Guanghui hesitated for a while, but still agreed.

Just as he was walking back, he saw Su Zhe and pulled Su Zhe and Si Wenbo to sit together.

When Bao Zhengyi saw this scene, he wanted to laugh in his heart.

The two professors showed off in front of Su Zhe for a while, but they were killed by Su Zhe, and the picture was ......

He looked at the time, there were still five minutes before the start of the technical presentation, and looked at the more than 100 people who were discussing at the scene.

I thought to myself, these people would definitely be surprised when they knew that the DYN-ion beam polishing technology was independently developed by Su Zhe.

He looked at Su Zhe, who was sitting with Senior Brother Niu and Si Wenbo, and looked forward to what kind of surprise Su Zhe could bring him? Is the discovery really worth several Nobel Prizes, as Su Zhe said?

……

Su Zhe was a little confused!

As soon as I entered the No. 1 lecture hall, before I could see how many participants there were, I was pulled over by Professor Niu Guanghuiniu and Professor Si Wenbosi.

After the three of them sat down, they listened to Professor Si Wenbo Si say to him: "Su Zhe! How much do you know about optics? Is there an undergraduate level? ”

"Yes!" Su Zhe nodded.

"That's good! After a while, when I discuss the plasma EUV light source with Professor Niu, you should pay attention to it, how much can you remember, how much you can learn, which will be good for you in the future. Si Wenbo advised.

"Good!" Su Zhe nodded, "That, isn't it a technical report meeting for a while?" We ......"

"There are only a few valuable words about the technical report, and the important information will be placed at the beginning and the end, and the rest of the time is on display, and it doesn't matter if you listen to it or not." Niu Guanghui said with some embarrassment.

"Got it!" Su Zhe understood that this technical report would really be as Fan Xiaoming said, it was used to brag and show off.

Seeing this, Niu Guanghui began to whisper: "This plasma EUV light source uses infrared light with a wavelength of 10.6 microns to irradiate tin droplets, and then ......."

Su Zhe listened carefully, he knew that the reason why Professor Niu gave a comprehensive introduction to the principle of plasma EUV light source was to take care of him.

After listening, he had a preliminary understanding of plasma EUV light sources.

The CO2 laser produces infrared light with a wavelength of 10.6 microns, which then irradiates tin droplets, which absorb 10.6 microns of infrared light and release ultraviolet light with a wavelength of 13.5 nanometers, and finally converge ultraviolet light.

After Niu Guanghui's quick introduction, Bao Zhengyi stood on the stage and shouted loudly.

"Everyone, be quiet! The technical presentation will begin immediately. ”

……

"Everyone has traveled thousands of miles to Shangling University, so I won't mess with you. Let's talk about the results of the seventh test. ”

"Looking at the big screen, our seventh test was done by two groups at the same time, one of the test results in the invitation letter, the lens accuracy reached 0.09 nanometers of surface accuracy peak and valley value and 19 pitrometers of surface roughness, and the other group is not bad, reaching 0.08 nanometers of surface accuracy peak and valley value and 18 picometers of surface roughness."

As soon as Bao Zhengyi's words fell, the participants in the lecture hall were boiling.

"Two groups! That's stable! ”

"I thought the accuracy in the invitation was high enough, but I didn't expect the other group to have a peak-to-valley value of 0.08 nanometers of surface accuracy and an surface roughness of 18 picometers."

"This ...... This is a bit exaggerated, much better than Europa's Chase, and now it's really going to change. ”
