Chapter 484: The Experiment Officially Begins

The weekend passed.

Monday, 9:00 AM, Xu Qingzhou's team held their first group meeting in an office specifically allocated by MIT.

MIT has multiple quantum nanofabrication platforms.

Xu Qingzhou's team was assigned to QuantumNanoFab, a small laboratory, with relatively old equipment, but it wins in being able to occupy most of the laboratory's time, occasionally sharing the use of equipment with other groups.

This can't be compared to the hundreds-of-square-meter school-enterprise cooperation laboratory newly built by James' team, but it can basically meet the experimental needs, such as graphene preparation, ALD deposition, thin film stripping, and other experimental content.

However, the final superconducting test and structural characterization analysis all need to be carried out in other laboratories.

This is very normal; the liquid helium recovery and magnetic shielding in the superconducting test system require special infrastructure, and there is no way to coexist with other equipment, while large characterization equipment like TEM, the price is there, and independent operation and maintenance are more economical.

Xu Qingzhou was still at the door when he heard Carson's voice in the office.

"Tsk tsk, our team hasn't started the experiment yet, and we've already become famous at MIT. Facts prove that my choice was indeed correct!"

Xu Qingzhou's expression was complex; sure enough, people who can streak are indeed extraordinary, and their brain circuits are indeed different.

Isn't the reason for becoming famous more because of the "talented" people in our team?

"Good morning, Professor."

"Good morning, everyone." Xu Qingzhou waved his hand, signaling everyone to sit down.

He didn't waste time either, directly entering the main topic.

"Traditional Nb3Sn thin film relies on rigid substrates, such as MgO, sapphire, but we use a new method this time, using graphene as a sacrificial layer, stripping the graphene after ALD deposition to obtain independent self-supporting Nb3Sn thin film, the thickness can be as low as 10nm..."

Xu Qingzhou said the general situation, and then asked: "Alright, I'll say this much, the rest are in the materials, does anyone have any additions?"

"I don't."

Sun Simin shook her head timidly; this was her first time participating in such an experiment, and her mind was blank.

"Me too." Ma Ma Ersi shrugged.

Xu Qingzhou's gaze looked at Carson, the other pillar in the team besides him.

Carson nodded, took over the conversation: "The materials and experimental plan are very complete, Professor. This is a money-burning experiment."

Xu Qingzhou had long thought of this point, saying: "In terms of funds, I will solve it."

Doing experiments, various problems will only appear when you actually do it.

Carson nodded, smiling and saying: "Then there is no problem at all."

Xu Qingzhou tapped his pen and said slowly: "We have four people, divided into two groups, responsible for testing at different times."

"Ma Ma Ersi and I are in a group," Carson said without thinking. After speaking, he apologized to Sun Simin: "Sorry, if my girlfriend smells the perfume on me, she might make the news again."

Sun Simin obviously also knew Carson's deeds, covering her mouth and nodding with a smile.

"Good."

Xu Qingzhou nodded slightly. Four people, he hadn't fought such a wealthy battle since his rebirth, and the personnel were more sufficient than when he did crystal experiments back then.

He continued to arrange work: "This week, our main task is to debug the equipment. Sun Simin, Ma Ma Ersi, you need to be familiar with the equipment this week, and at the same time, you must finish reading all the materials."

Doing experiments, you can't be as casual as usual, and as a leader, you often need to have an attitude of being duty-bound.

Graphene transfer system debugging, ALD system debugging, stripping and transfer system joint debugging, etc., all take at least a week.

Xu Qingzhou finished the work arrangement, the four of them changed into white coats, and drilled into the laboratory.

Monday, mainly for reaction chamber sealing verification.

Carson volunteered to be responsible for the operation.

"Start the vacuum pump, pump to the reference vacuum degree, let it stand for 1 hour, the pressure fluctuation is less than 5% to be qualified..."

Carson explained to Sun Simin and Ma Ma Ersi while starting the equipment.

The two rookies also took notebooks and *brush-brush* recorded.

Carson glanced at Xu Qingzhou who was standing by and not speaking, thinking to himself that Xu Professor is a mathematician after all, and has quite high attainments in theoretical physics, but in practical operation, he shouldn't be as skilled as me.

Having worked for his teacher for seven or eight years, Carson still had some confidence in laboratory operation.

Of course, he didn't feel that Xu Qingzhou knew nothing about these devices, because according to his understanding, Xu Qingzhou had also done physics experiments.

Debugging steps: Equipment initialization -> parameter configuration -> deposition cycle debugging -> AOI detection -> performance optimization process.

Time soon reached the afternoon.

"Why is the light on here? Leave it to me, a long time ago my supervisor and I used this kind of equipment, although... it's a bit different, but fixing it is no problem." Carson frowned.

Sun Simin and Ma Ma Ersi nodded to show they believed him.

Xu Qingzhou wasn't in a hurry either, checking the operation of the vacuum pump.

10 minutes passed.

Carson stared at the fault light and couldn't help but mutter: "This instrument should appear in a museum instead of here."

"Let me see."

Seeing Carson couldn't fix it for a long time, Xu Qingzhou decided to do it himself. The deposition system here is a relatively old Beneq TFS 200, which is not the same as the advanced equipment currently available.

He looked at the screen and soon found the problem: "Because the equipment is relatively old, the 0402 capacitor is identified as a resistor."

"Ah, found it just like that?"

Carson was a bit unbelievable.

"If you're lucky, it should be."

Xu Qingzhou manually adjusted the parameters.

Carson watched Xu Qingzhou operate on the side, his gaze sinking. How should he put it, Xu Qingzhou gave him the feeling of an old professor as soon as he started.

That's right, it's the kind of calmness he felt from his teacher, the confidence that everything is under control.

But... Xu Qingzhou isn't even as old as him, right?

Is this the common temperament of big shots?

Xu Qingzhou said at the same time: "This thing is like library classification relying on correct labels, drug dosage relying on accurate units, ALD system detection relies on the precise matching of component types and parameters. Once the registration information is wrong, the system will execute detection based on the wrong standard, leading to distorted results."

As soon as his words fell, the error prompt light disappeared.

In the laboratory, except for Xu Qingzhou, the three young people were all stunned.

No, it's fixed just like that?

Carson stared at the screen for a long time, confirmed there was no problem, and turned his head: "Professor, you... aren't you a mathematician?"

Only those professors with sufficient experience can find the problem at a glance.

"Obviously, my physics is also quite good." Xu Qingzhou gave the position to Carson and smiled lightly.

"..."

Carson was speechless, showing an expression of admiration, "Awesome."

Beside, Sun Simin and Ma Ma Ersi looked at each other, their eyes full of worship; although they didn't know how the professor found the problem, the operators on the screen were already impressive.
