Chapter 718: Even if it's bent, you have to straighten it out for him

Laboratory.

"Laser interferometer observations show irregular burrs or diffusion layers appearing at the plasma boundary, indicating that the plasma boundary blurriness exceeds the standard," Zhao Shengwen said helplessly.

Xu Qingzhou checked all the data on the computer and frowned: "The configuration control accuracy requirements for negative triangularity plasma are extremely high; the current data clearly doesn't meet the standard."

"There's no way around it. People say they cross the river by feeling the stones, but we're doing negative triangularity plasma without even stones to feel; we can only trudge through it."

Zhao Shengwen gave a bitter smile; he was really a bit anxious now.

Just a few days ago, the Princeton Maxwell team officially announced the completion of the superconducting thin-film project, with performance reaching a Jc value of 5.0×10^6 A/cm², on par with Xia Nation's technology, and it had already been successfully used in the US National Ignition Facility (NIF). It is expected that they will complete the world's first net energy gain recently.

That is to say, the output energy is more than the energy triggering the reaction.

The Americans have caught up, but their plasma is facing numerous difficulties.

"As the first person to eat crab, it's normal to take some detours."

Xu Qingzhou had a good mindset and checked the cross-section image of the electron microscope.

Traditional tokamaks have adopted positive triangular configurations since the 1950s, while negative triangularity was only a theoretical hypothesis. After 2010, spherical tokamaks, such as the UK's MAST, attempted negative triangularity but did not reach fusion temperature.

The core problem of fusion energy—plasma stability and thermal management—is where negative triangularity plasma has considerable advantages.

The problems are also obvious.

The technology maturity is not high, but the precision requirements for the equipment are ridiculously high. Just talking about the magnetic field coils, the positioning error requirement is less than 0.1mm, while the traditional requirement is only less than 1mm.

Material compatibility is also a problem; the existing tungsten-copper alloy divertor has its lifespan shortened by 40% under negative triangularity, which means they have to redesign the divertor.

According to the calculations provided by Zero Point Technology, due to the need for ultra-high-precision magnet systems and multiple redundant cooling units, the cost will basically reach 180% of a traditional tokamak, and maintenance costs will also increase by 50%.

Therefore, current large tokamak devices are still based on positive triangularity.

"I'll go back and think about it."

Half an hour later, Xu Qingzhou left with the data. Regarding configuration control accuracy, he had a vague idea and needed to go back and organize it.

He was now a brick; he could be moved wherever he was needed.

In the laboratory, watching Xu Qingzhou's departing back, Gong Yunfei couldn't help but sigh: "Working with Junior Brother always gives one a feeling of being rubbed against the ground."

The gap was too big.

"I thought of a sentence the teacher often said in high school."

Wang Wei agreed and said from the side: "Breaking down knowledge points and feeding them to your mouth... I never thought that even as a researcher, one could still have this kind of experience..."

"What are you two nagging about? Get to work and analyze the peak value of A2."

Zhao Shengwen glared from the side. Actually, he also thought of a sentence: the waves behind the Yangtze River push the waves in front, and the waves in front die on the beach. Trying to keep up with this kid's rhythm was really a bit strenuous.

Rongcheng, Human Resources and Social Security Bureau.

"I smelled the tea at the door. Old Meng, hurry and give me a cup of tea; I'm dying of thirst."

A middle-aged man wearing glasses walked in and sat down in a chair with a thud.

The person called "Meng Jie" asked with a smile: "Oh? A rare guest. How does Director Chen have time to come to us?"

"To pick up materials."

Chen Yunhao sighed and took two gulps of tea. "Someone is preparing to buy a house, and the higher-ups asked me to arrange it. Isn't this coming to you to get the talent identification materials?"

"Oh? A house, whose residence requires you, this director, to run around looking for it?"

Meng Jie was a bit surprised and added tea for Chen Yunhao again. ===== CHAPTER 719 =====
