80s Returning Doctor

"That is to say, there are very few people who can think like you. Who doesn't like the top scientific research equipment!" For example, if he can get this opportunity, he is not sure whether he can stand the temptation.Can't think, can't think, he will definitely stay in Huaguo in this life, and he will dedicate his life to Huaguo.

"Everyone has their own love, I can't represent others." Since returning to China, too many people have asked him these questions, and He Jing just feels very tired and bored about this, and doesn't want to continue to respond at all.The fact is that he has already returned to China, he has made a choice, and everything is over.

Seeing that He Jing was not interested, Zhou Chenghe changed the subject with a wink, "Brother, you are going to teach next semester, have you decided what class you want to teach?"

He Jing shook his head, "It's not confirmed yet, let's see how the department arranges it then!"

Zhou Chenghe nodded clearly. He Jing is only a lecturer now, and he probably won't join him until the associate professors above are selected. The courses that can be selected should be relatively basic.

"Then you should also pay attention. It is estimated that the course schedule will start in half a month. You can ask early, and you can take the initiative. Like our project team, the project stage report is on Monday morning, so It’s best not to schedule classes on Monday morning. In addition, we often go to the processing factory for technical maintenance on Wednesday afternoon, and it’s best to avoid this point, and there’s nothing else.”

"Thank you, I understand." He Jing was a little moved, this junior brother can be said to be really good to him.

"You're welcome, you're welcome, you're my senior brother, I deserve it all." Zhou Chenghe smiled shyly, he was hugging his thigh in advance.

After eating, the two returned to the laboratory. He Jing didn't have the habit of taking a lunch break. He poured a glass of water and sat in his seat before continuing to read the materials.

One day is enough for He Jing to read all the materials, record some of his thoughts by the way, and improve these thoughts.But after all, it was the first day of work, so He Jing did not leave as soon as the off-duty time came, but planned to continue to improve the information in hand.

One of the most important functions of the cyclotron is its medical application, which can produce radioactive isotopes, which can be used to make radiopharmaceuticals.It can also perform medical imaging. In the future, many large hospitals will have their own cyclotrons, and its importance is obvious.Having a more advanced cyclotron is also crucial to the development of medical care, not to mention nuclear physics.

It has been more than 1930 years since the cyclotron theory was proposed in 50, and several systems have also been developed.Huaguo has been committed to this research since the founding of the country, and even built the first cyclotron in 1958, producing 33 radioactive isotopes. Since then, related research has continued to make breakthroughs.Of course the research is endless and they need better equipment.

At present, the isochronous cyclotron with superconducting magnets is popular in this era, which greatly increases the efficiency of the accelerator and produces more elements.Moreover, the application of superconducting technology has made the volume of the machine smaller, and the operating cost has also been reduced a lot.

What Professor Qiu and the others are currently doing is to use superconducting technology to apply it to isochronous accelerators. Many technologies have already been broken through, but innovation is a very difficult thing.It is difficult to create a technology, but it is even more difficult to make a new breakthrough in a technology.

Under the dim light, He Jing drew the internal structure diagram of the accelerator with a pencil on white paper. Zhou Chenghe, who was sitting next to him, had already got off work. He was the only one in the laboratory at this time. He Jing was very focused, like It's like you can't feel the movement around you.

There was a sound of stomping, and the leather shoes fell on the floor with a dull sound. Professor Qiu walked into the office with a briefcase. He rubbed his brows tiredly. He was very tired of the day's meetings.But the sudden thought made him unable to bear to go to the verification tomorrow, so he came directly to the laboratory.He was very surprised when he approached the office. The warm yellow light came out from the door. It stands to reason that there should be no one in the office today.

He walked in lightly, and was surprised to find that the person staying in the office was actually Dean Han's senior student whom he met yesterday, Dr. He who had just returned from studying in country M.Oh, by the way, he came to their project team to report today.

He didn't want to disturb the people who were very focused and busy, but he was really curious. He walked behind He Jing carefully, and his eyes fell on the structure diagram of He Jing's pen. He raised his eyes and looked carefully. is a diagram of the internal structure of a cyclotron.

He stood still and waited patiently for He Jing to continue drawing. Parts slowly appeared on the white paper, and Professor Qiu's eyes became more and more hot.

He Jing paused for a while, the long-term posture made him a little uncomfortable, he shook his shoulders left and right to relax, and he planned to rest for 2 minutes.

"continue."

He Jing was startled, turned his head quickly, and then stood up quickly, unexpectedly seeing a person he didn't expect at all, "Professor Qiu?"

Professor Qiu raised his chin towards the drawings on the table, "Continue to finish drawing."

"Oh, good." Although he didn't know why this person came back in this era, He Jing sat down very obediently, and continued to draw quickly with a pen in his hand. This blueprint was originally thought of by him. Not much to think about.

About 10 minutes later, He Jing completed the last line. Before He Jing put down his pen, Professor Qiu leaned over and took the drawing from He Jing's desk to his hand.Professor Qiu didn't speak, but just looked at the blueprint in his hand intently.The atmosphere was a little stagnant, and it was not good for He Jing to disturb him, let alone continue to sit, so he also stood up, just standing quietly beside Professor Qiu.

As time passed, He Jing always felt a little uneasy, as if he was facing the most important exam in his life.Even though he is from the 21st century and has more advanced knowledge, naturally it seems to stand taller than these people.But the reality is that these people are much greater than him, and what they have is richer than what He Jing has, and they are objects that He Jing needs to look up to.

Finally, Professor Qiu moved his eyes away from the blueprint and landed on He Jing. He shook the blueprint in his hand, "Is this what you think of yourself?"

He Jing nodded, "I have been in contact with cyclotrons in country M before. Most of them are drawn based on real objects, and some are my own ideas." Even though I have been in contact with real objects, there are still many uncertainties about the specific internal structure. Some of the blueprints were indeed thought up by He Jing himself.

Professor Qiu nodded knowingly. After all, He Jing came back from abroad. He must have been exposed to many research projects in the past four years. It is normal to see the cyclotron. The rare thing is his own thoughts. It is very good at this age. up.After confirming that the person in front of him should be a person with real talent and learning, Professor Qiu's attitude towards He Jing also eased a lot.

"The drawing is very good. How do you think about this place? The fringe magnetic field?"

I was tested!He Jing was excited in his heart, but he was very patient on the surface, "The design of the fringe magnetic field can change the ion orbit of each stage of the accelerator tube... This is more conducive to aligning more molecules."

"Then how much ion energy do you think can be achieved with this design!"

"If the experimental environment is ideal, I think it can at least reach 20 to [-] times the natural radiation energy!"

Professor Qiu raised his eyebrows in surprise, "How did you come up with this number?"

He Jing smiled confidently, "Now the latest accelerator in the world can reach about [-] to [-] times, and I have added variable control to the drawing. If we can break through this technology, I think the energy can Breakthrough to the value I said."

"This is superconducting technology!" Professor Qiu was not very optimistic.

"Huaguo has already done related research. I know that the Institute of Atomic Sciences has made many breakthroughs in this technology. We can seek each other's help to tackle difficulties together."

After He Jing finished speaking, he found that Professor Qiu had a dignified face, and he was a little worried. He seemed to be talking too much accidentally. As a newcomer who had only joined the project team for a day and hadn't even done a preliminary experiment, he seemed to be talking too much.However, he does not regret it. If he can cooperate with the Atomic Research Institute as soon as possible, he believes that they can produce results faster, and there may be major technological breakthroughs.In this era, the news is still too backward, and it is difficult to achieve a sufficient optimal allocation of resources.

Time passed quietly, and just when He Jing felt uneasy and couldn't help moving his feet to speak, Professor Qiu laughed and nodded to He Jing with satisfaction, "It seems that you did a lot of homework before you came back. He even inquired about the atomic research institute."

Oops, I seem to have slipped my mouth. How could he, a person studying abroad, be better informed than people in China?His mind turned quickly, and he immediately thought of a person, "I have a classmate who works in the Institute of Atomic Sciences, and we have been communicating."

He does have such a classmate, and the relationship is indeed very good. Even after studying abroad, he has been communicating with each other, but the things about work are just exchanges of ideas. Of course, He Jing does not know the specific projects, but it is enough. up.

Professor Qiu had no doubts at all, and just nodded casually to He Jing's explanation. What he was more concerned with now was whether He Jing's idea could be realized.

"You think we should work with them?"

Of course, with a good partner, it will get twice the result with half the effort. "They have an advantage in superconducting technology. If we can break through as soon as possible, we can reduce research costs and production costs. After that, we can produce medical cyclotrons as soon as possible. Only by reducing the cost of use will more patients be able to Enjoy the benefits of this device.”
