Scholar’s Advanced Technological System

This laboratory is an "industry" of the Max Planck Institute of Plasma Physics, but this type of global research is certainly not just a unit of the Plasma Physics Institute.

Lu Zhou has seen the list of cooperative research units, and the names of those research units alone are enough to fill a page of A4 paper. If the signature principle of the paper is the same, as long as everyone involved in the research has a copy, I am afraid that the first few pages of the paper will have to be freed up to write the signature.

However, compared to this large collaborative research group, the stellar as the research object seems to be "small".

Following Professor Kreiber's footsteps, Lu Zhou and Professor Keli Qing came to the radiation-proof isolation room and finally saw the whole picture of the spiral stone 7-X.

Quietly located in the center of the radiation-proof isolation room, the star-like device, about 3.5 meters high and about 16 meters wide, looks like the "Millennium Falcon" of Captain Han Solo, a smuggled cargo ship in "Star Wars."

It has just experienced a big war, and it is docking in the "Starport" at this moment, and it can only be repaired by technicians.

Approaching the past, Lu Zhou could clearly see that equipment of various sizes were densely scattered on the surface of the device, and countless cables spread from the equipment to all directions, seemingly tangled together.

"This thing ... how much does it cost?"

"It is said to be more than one billion euros." Looking at this device, Professor Klitzing, who was standing beside Lu Zhou, said with some envy, "If you count the R & D costs together, I am afraid it is an astronomical figure."

The funding of the Institute of Plasma Physics is especially enviable among colleagues in physics.

Obviously it is also the Max Planck Society, and it is also the Institute of Physics, but the condensed matter physics institute has a lot less funding than them.

I envy Gui En, and Klichen understands this.

After all, this kind of cooperative R & D project involving multiple countries is not only funding the German government, but countries around the world are throwing money at it.

"Is it so expensive?"

Lu Zhou smashed his tongue.

Originally, he was still a bit swollen and thinking about whether or not to come over to study and research, but now it seems that it is more realistic to have a Taiwan supercomputing ...

"Well, don't worry about how much money, the budget is not something we need to worry about," patted Lu Zhou's shoulder, Professor Kleiber said with a smile, "the final debugging has been completed, and the experiment is about to begin. Go to the observation room. "

...

Unlike experience at work, Hadron Colliders run underground at a depth of 100 meters from beginning to end. Unless they have a professionally qualified engineer, they cannot enter the pipeline at all.

What appears to theoretic physicists is only the data on the screen and the further processed images.

But now, in front of Lu Zhou, in addition to the detectors connected to various parts of the stellar, he can even observe the internal conditions of the orbit with the naked eye through a thing similar to a camera.

All staff are waiting in the observation room.

"Rail tightness test is OK!"

"Fill with protective gas!"

"After filling the protective gas, start the pressure measurement procedure!"

"..."

"The superconducting critical temperature is reached and the circuit is fully charged!"

"Magnetic field operation confirmed normal!"

After listening to the reports from the research groups, Professor Kleiber immediately issued an order to start the experiment.

"ignition!"

The moment when the magnet current reached 15kA, the thyristor was quickly turned off, and the magnet current was transferred to the first-stage energy-dissipating resistor, generating a voltage of 2400V, causing the gas in the vacuum chamber to be broken down, thereby generating a plasma.

Lu Zhou saw through the screen that a layer of pale red film-like material formed a twisted ring in the twisted circular orbit.

To his surprise, the scene was quite beautiful.

"... The temperature of these plasmas will exceed hundreds of millions of degrees after peaking, which is almost equivalent to the interior of the star. No material can block this hot energy, even if you have searched the solar system, it is impossible." Looking in front of the screen, Professor Klitzing whispered beside him.

Lu Zhou asked casually, "How did the imitator do it?"

"Relying on twisted magnetic fields," explains Professor Klitzing, "we use magnetic fields to constrain them, restrain them in a limited space, and keep them away from the inner wall of the orbit. But even so, it can't hold on for too long ..."

While the two were talking, the experiment had entered the most critical moment.

With the secondary energy dissipating resistor, the thyristor switch closed, the voltage dropped to 1000V, and at the same time the current rose to the peak, and the entire track was suddenly filled with hot light, even if it was across the screen, it felt a bit dazzling.

However, this light did not last long.

In less than six seconds, the light suddenly slackened, and disappeared into the screen like an extinguished flame.

The star simulator in operation gradually stopped, but the observation room was quickly busy like boiling water.

Standing not far from the two, Professor Kleiber ordered the researchers in the observation room: "Collect the data immediately, check the condition of the equipment, and move fast!"

At the same time, the door of the radiation protection isolation room opened, and the staff wearing radiation protection clothing quickly entered the isolation room with various tools and began to check the condition of the track from a physical level.

Looking at Professor Kreiber who had taken off his helmet, Lu Zhou staggered slightly.

"That's over?"

"Yes, it's over," Professor Kreiber, who threw the helmet onto the table and walked over, said with a smile, "Now it only takes a few seconds to discharge at a time, and the longest I remember is about 6 seconds. , In the shortest time, only a few picoseconds. "

Lu Zhou's face was speechless.

"... I thought it would perform even more amazingly."

Professor Kreiber grinned: "In theory, it can make the discharge time longer, but now the target of the diverter filter has not been installed properly. If the discharge time is too long, it may cause excessive heat load to damage the first wall Materials. After another two years, the water-cooled deflector is installed and you can try a 30-minute pulse discharge. "

The discharge time here refers to the time during which the basic magnetic field configuration can be maintained in one discharge, which is the so-called pulse time of one discharge.

30 minutes is the goal set by Spiral 7-X at the beginning of the design ~ www.readwn.com ~ If it can be done, the impact on the entire nuclear fusion project will undoubtedly be huge, and it will even affect the international community on nuclear fusion Selection of mainstream technology routes for engineering.

After all, the mainstream choice is the tokamak device, but the tokamak device has fallen into a bottleneck in the discharge time.

At present, the longest discharge record held is 102 seconds of the "EAST" of Huaguo, which almost marks the ceiling of the technical route of the Tokamak device on the "discharge time". If you want to raise this ceiling by an inch, You have to pay an expensive price.

Looking at the device, a thoughtful expression appeared on Lu Zhou's face.

Suddenly, a whimsical thought came to his mind.

If the system is to price magnetically constrained nuclear fusion technology, how many points do you need for a mature stellar drawing? -

(It's better to get cold today. I'll try to break out tomorrow. I can't go down with salted fish like this. In short, let's talk about it first ...)
