Zhang Weiqing interviewee confessed pictures

In 2022, it was the tenth year of Zhang Weiqing's research on the research of free electronic laser.

Zhang Weiqing, who was just awarded the title of "Most Beautiful Science and Technology Worker" in Liaoning in 2022, was a researcher at the Dalian Institute of Chemistry Physics (hereinafter referred to as Dalian Huapi) of the Chinese Academy of Sciences. As a deputy chief engineer, he led the team to successfully develop the "Comprehensive Experimental Research Device based on the adjustable extremely ultraviolet light sources" (hereinafter referred to as Dalian related light sources). This is my country's first high -gain free electronic laser large -scale user device. It is also the only free electronic laser device in the world that works in extremely ultraviolet bands. It is the brightest source of extremely ultraviolet light in the world.

Speaking of these 10 years of scientific research, Zhang Weiqing laughed: "I never feel tired, because this is my interest, my hobbies, and my time in the laboratory is my happiest time."

10 years ago at the laboratory in the Laboratory of the Map Institute in Germany, it seemed to be reunited with the scenes working in the Dalian Institute of Huasian. Pass.

8500 kilometers to hear the mission call

In 2012, in the laboratory of the Map Society Institute in Munich, Germany, Zhang Weiqing, a "Humboldt scholar", was engaged in post -doctoral research.

For more than two years in Germany, Zhang Weiqing's study and life is colorful. He has been engaged in research in the field of physical chemistry since the undergraduate. In this direction, he has developed deeply, such as fish, and the overall research progress is very smooth.

At this moment, Zhang Weiqing suddenly received the information from doctoral supervisor Yang Xueming. "Teacher Yang said that the free electronic laser project -the relevant light source of Dalian is‘ recruiting soldiers and horses ’, asking me if I want to come back.” Zhang Weiqing said.

Zhang Weiqing stood at the bifurcation of the "two -choice". On the one hand, it is a familiar scientific research field, and continuing to study may soon achieve important scientific research results. On the other hand, the construction of the relevant light sources in Dalian is a new field of engineering, which is far from the basic science fields that they are familiar with. In the next many years, high -level papers may not be published as before, which will be a lack of scientific research career. Entering a new field of engineering is equivalent to entering the "virgin land", it is not easy to open territory here.

"At that time, the research on free electronic laser in China was mostly its own research and development. Related instruments existed as a test device. It could not be provided to users by 24 hours." Zhang Weiqing introduced. Only two or three units are running. In principle, domestic scientists can apply for a light source machine, but the probability of actually obtaining the machine is not high. "

If there is no high -brightness free electronic laser user device, many scientific research projects in this field will lack key tools, and the research process will be greatly delayed.

Thinking of this, Zhang Weiqing did not hesitate. After dealing with Germany's research work, he immediately embarked on a flight to the country.

At the distance spanning 8,500 kilometers, Zhang Weiqing obeyed the country's call and accepted difficult tasks, and resolutely moved towards this new field.

100 kilometers of ice days can't stop the Heat heart

Zhang Weiqing, who had just returned to China, was too late to rest, so he pierced into the project.

Thanks to the detailed planning of the team, the progress of the initial preparation stage of Dalian related light sources is smooth. Everything is ready, where should the "wind" be scraped? Where the equipment "landing" has become a problem that the team needs to solve.

After communication and coordination, the relevant light source of Dalian chose to settle in Changxing Island, Wafangdian, Dalian, a small island 100 kilometers from Dalian.

Before the construction of related light sources in Dalian, the team needs to conduct field surveys to understand the terrain conditions, and consolidate the foundation for subsequent research. In the winter of 2014, the construction of Changxing Island Park has just begun, and there is a lack of various supporting facilities. The inconvenient meal and accommodation conditions, no heating, hydropower facilities have no complete problems ... each of them follows, and test the psychological quality of the team personnel with the cold winter.

"But the project doesn't wait for anyone, we want to" grab "to install the equipment, save time to prepare later." Zhang Weiqing said.

Inadequate hydropower facilities, the team built temporary facilities by themselves. When installing and debugging the most critical, scientific researchers eat and live at the scene to ensure the progress of construction.

On the island 100 kilometers away from home, Zhang Weiqing and the entire research team used the hottest and purest scientific research to fight the cold outside.

In less than two years, Zhang Weiqing and the research team (the joint team of Dalian Chemical Institute and the Shanghai Institute of Applied Physics of the Chinese Academy of Sciences) overcame the various unfavorable conditions on the scene, experienced the fighting day and night, and gave up a lot of rest. Time has finally completed the development of major infrastructure projects and main light source devices, realized the first spontaneous radiation of light from the light source device, and set a new record for the construction of similar large scientific devices.

Zero -distance interest and occupation "do not distinguish"

In 2018, the relevant light source of Dalian passed the acceptance. Recalling the scene of acceptance, Zhang Weqing is still very excited to this day: "About 5 years, I devoted myself to this matter, just like" raising children "."

From the beginning of the greetings full of joy, to pouring all his efforts to pour in the future. In the past few years, Zhang Weiqing did research and did research and seriously engaged in scientific research. In the end, the project "Blossom and Result" cannot be separated from the word "persistence", and behind persistence, Zhang Weiqing has another "little secret". He told the Journal of China: "My teacher, Academician Yang Xueming said," I am a lucky person, I have been doing what I like in my life '. I have always resonated with this sentence. "Zhang Weiqing Since high school, he has been interested in science. During his college, he studied in the Department of Chemistry and Physics of the University of Science and Technology of China. During his Ph.D., he studied physics and chemistry in the Dalian Institute of Chemistry. It can be said that he has been dealing with this field for more than 20 years. To do scientific research, it takes a long time to work, and wants to be "long" and cannot be separated from the irrigation of "fertilizer". For Zhang Weiqing, energy originated from love.

Today, Zhang Weiqing has faded from tender, growing from a student to the leader and teacher of a scientific research team, and the team has grown from more than 10 people to more than 50 people. In this team where the average age is less than 35, he uses his love, concentration, and insistence to pass his energy.

"On the road of scientific research, Teacher Yang often encouraged me to pass on the passion and focus of his scientific research to me. I also hope to bring students more energy, let them do what they like, and create value by themselves." Zhang Weqing Say.

Time to become a sword, Zhang Weiqing will take his own love and belief to go to the farther mountain.
