94: From Technological Warfare to Space Empire

Chapter 122 Let's do this for three days! We'll completely drain him!

Professor Yang said, "We failed more than 300 times, but we analyzed the reasons for each failure."

"Some problems stemmed from misdirection, some from equipment malfunctions, and some from operational errors."

He handed this thing to Lin Yu.

"In the end, it's just a notebook of wrong answers."

"Take it if you need it; these things might help you avoid some detours."

This thing embodies three years of youth and three years of sweat from many people.

Lin Yu carefully put it away, then looked at Professor Yang with gratitude.

"Thank you, Teacher Yang."

"We won't take the equipment for free; we'll use our funds to purchase it."

Professor Yang patted him on the shoulder.

"Alright, get the job done!"

"Make the BEC so that we old guys can see it with our own eyes."

"What is the fifth state of matter?"

Lin Yu nodded vigorously.

"must!"

Just then, the sunlight streamed in through the window and shone on them.

The midday sun was extremely intense.

It felt hot against my skin when exposed to the sun.

Many students were still there, gathered in twos and threes to discuss things, some inside and some outside.

Several of Professor Yang's students were also peeking in this direction.

Doing scientific research in this era is extremely difficult.

No money, no equipment, no resources.

Only passion and perseverance.

And the purest love for science.

Now, this passion, this perseverance, and those simple, cutting-edge research methods—all contribute to this journey.

Everything will come to him.

Now, he has arrived.

BEC, Bose-Einstein condensate.

The fifth state of matter.

Let him do it!

a few days later.

In late March, spring was in full bloom in Beijing.

In the old laboratory building of the Institute of Physics, Chinese Academy of Sciences.

It was a scene of bustling activity and great activity.

When Lin Yu received Academician Zhou's call, it was already the eighth day after that lecture at Tsinghua University.

During this period, Chief Hou and Engineer Chen from Sinopec handled most of the inquiries from people all over the country about unleaded gasoline.

-

Lin Yu was finally able to go out and go back to the factory for some fresh air.

Academician Zhou had already called Beihang University and the military compound, and finally found Lin Yu on a landline at Hongxing No. 2 Factory.

On the other end of the phone, the old academician's voice carried a rare hint of urgency.

"Xiaolin, all the equipment is ready, come and take a look?"

Lin Yu hadn't expected Academician Zhou to act so quickly!

With all the equipment in place and the lab set up, they can get started!

Lin Yu couldn't bother continuing to instruct everyone in the factory.

Wearing the factory uniform, he dashed out as fast as he could.

He ran alongside shouting, "Zhang Guoqiang! Zhang Guoqiang!"

"Let's go! Pick me up and take me to the Chinese Academy of Sciences!"

When Lin Yu arrived at the Institute of Physics.

He followed the person Academician Zhou had sent to meet him at the door and ran all the way to the laboratory.

When I pushed open the door to the specially modified laboratory, I was stunned.

The laboratory was densely packed with all kinds of instruments.

The optical paths for the six laser beams on the optical platform have been set up.

The mirrors, beam splitters, and waveplates were all adjusted neatly.

The vacuum system was also humming.

The titanium sublimation pump and the ion pump are connected in series and are working.

The magneto-optical trap appears to be the same system that Professor Yang taught him a while ago.

It is made of oxygen-free copper coil.

Academician Zhou stood in front of the optical platform, surrounded by seventeen or eighteen young people and three or four senior professors.

Upon seeing Lin Yu approach, Academician Zhou's usually stern face broke into a rare smile.

He waved to Lin Yu.

"Come on, let me introduce you. These are some promising students I picked from physics and Tsinghua University."

"A few of them were recommended by Lao Yang."

"From now on, you'll study BEC with us."

Lin Yu glanced at the young faces.

The younger one is in his early 20s, and the older one is almost 30.

Their eyes all showed respect for Lin Yu.

Whether it was the unleaded gasoline or Academician Zhou's introduction, they all understood what a genius scholar the young man in front of them was.

Lin Yu was introduced to the Institute of Physics by Academician Zhou. There were people from Peking University and the Chinese Academy of Sciences in the institute.

Those who came from Tsinghua University had all attended his lecture.

"This is Xiaolin, Lin Yu. You should have all heard of him."

Academician Zhou introduced Lin Yu to the group of people.

"He has the final say on the next experiment."

The young men nodded respectfully.

Lin Yu didn't say much. After a brief greeting, he went to the optical platform to check each item one by one.

The laser is a Titanium Gemstone laser manufactured by Spectra-physics.

This is probably the best equipment that can be obtained domestically.

The vacuum chamber is made of stainless steel that has been cleaned by electrical discharge.

Lin Yu checked the parameters and found that the gas release rate could be controlled at 10 to the power of 10 Pa per liter per second.

The magnetic field gradient design of the magneto-optical trap is also fine.

Lin Yu checked each item one by one, silently calculating the parameters in his mind.

The equipment that Academician Zhou prepared is perfectly fine; theoretically, it's all feasible.

But once you actually start doing it, nobody knows what problems you'll encounter.

After a brief examination, Lin Yu nodded to Academician Zhou.

"Old Zhou, there's absolutely no problem."

Seeing that Lin Yu fully agreed, Academician Zhou also breathed a sigh of relief.

"Shall we check the experimental protocol first?"

Looking at the arrangement of various equipment, Lin Yu said what he had thought about countless times: "We'll use 87 atoms."

"Its wavelength is exactly 780 nanometers, with a large scattering cross section and high cooling efficiency."

"Moreover, its spin is an integer, a boson, which is suitable for BEC."

Several students quickly took notes.

Finally, Lin Yu talked about the cooling solution.

"Duoplet cooling is used first, followed by polarization gradient cooling, and finally evaporative cooling."

Lin Yu drew a simple diagram on the paper.

"The magneto-optical trap first captures the atoms, reducing their size to a few million Kelvin."

"Then we use a compressed magneto-optical trap to increase the density, and finally turn off the laser."

"At this point, a pure magnetic trap can be used to imprison them."

"By directing the laser radio frequency evaporation, it can be cooled down, causing it to reach even lower temperatures."

Lin Yu clapped his hands, drawing everyone's attention.

That's roughly how things went.

However, it's quite troublesome to deal with.

After Lin Yu finished speaking, the students looked at each other, and someone asked in a low voice, "When do we start?"

Lin Yu glanced at Academician Zhou, but the old academician waved his hand.

"You're the overall commander, you make the decisions."

Upon hearing this, Lin Yu didn't hold back at all.

Since he's being appointed as the overall commander, the sooner the better.

The laboratory is completely sealed.

Lin Yu had already changed his clothes when he entered the room.

"Then let's start today."

"Let's vacuum the air first."

"We'll talk about other things once we reach 10 to 11 Pa; that process will take at least 3 days."

The experiment cannot be completed in a short time.

Lin Yu led the group forward at a slow pace.

But the first accident still occurred a week later.
