Chapter 379: More transmit power! (four four)

There is not much time left for the "He-3" project team.
Everyone was like a clockwork clock, running against time.
Finally, with the efforts of everyone, a slightly rough prototype was finally completed.
The entire prototype is divided into two parts, one is an "atom gun" used to accelerate and emit helium 3 atoms, and the other is a target material installed in a vacuum chamber to receive helium 3 atoms. As for the computers and various observation components connected to the device, they are all necessary and need not be mentioned.
As for why the prototype is rough ...
That's because almost all parts of it are pieced together.
The acceleration orbit of the atomic gun was modified by a small particle accelerator eliminated by Argonne National Laboratory. The vacuum chamber used to confine the plasma is the experimental body that PPPL designed when it was studying stellarators.
The entire set of experimental equipment can heat the internal plasma to 7,000 degrees at most, which is far away from the high temperature of 100 million degrees. The electromagnetic field that binds the plasma is also more than an order of magnitude away from the 10T of the star simulator.
But even that is enough.
Any experiment starts with proving its feasibility. They don't need to complete a nuclear fusion ignition in this crude vacuum chamber, or even need to completely simulate the amazing density of the plasma inside the stellar.
They just need to successfully collect data from these plasmas and analyze the data to arrive at a more accurate "observation" conclusion than a plasma "diagnosis".
Finally, the problem of "method migration" is solved, so that this observation device can work on the stellarator.
In fact, Lu Zhou's original idea was that it would be nice if he could get the stellarators eliminated from the WEGA experimental group.
But he was just thinking about it, Professor Lazersson explicitly told him that the gadgets could not be bought with money.
In short, this prototype is considered complete!
The orbit of the particle accelerator is the "loading" of the atomic gun, and the target material that accepts helium 3 atoms is a tungsten-titanium alloy that is widely used in the impact experiments of high-speed charged particles. Behind the target material are probes with different sensitivities and functions for receiving impact data.
So far, although many problems have been encountered throughout the project, it has been generally smooth.
When the final commissioning was completed, Professor Lazersson was impatient to announce the start of the first experiment.
Researchers in the laboratory have endured countless days and nights for this project, and have paid countless hours of sweat. Now that the entire device has been assembled, they need a success to boost morale!
however……
Things are not going as smoothly as everyone thought.
The moment when the helium 3 atom was injected into the high-temperature pressure plasma, it was heated to the plasma state in a short time as expected. The detector connected to the outer wall of the simulation device also collected the helium 3 due to collisions and other reasons. Generated electromagnetic wave data.
Destiny seemed to make a joke with all the researchers here. The helium 3 atom emitted by the atomic gun did not pass through the plasma as expected.
No matter where it eventually shot, it did not hit the target material.
Apparently, they successfully fired bullets.
However, the bullet was not successfully recovered.
No doubt the first experiment failed ...
...
The 21st experiment is over.
The atmosphere in the laboratory was extremely heavy.
The probe installed behind the material still did not detect the signal from the helium 3 atom hitting the target material ...
Now that the experiment is running, they are facing the biggest bottleneck since the project began.
If the fired bullet cannot be recovered, the bullet will be meaningless.
The first to break the silence was an engineer with controlled nuclear fusion.
In an uncertain tone, he tentatively asked, "Will the sensitivity of the probe be insufficient? In fact, the impact has already occurred, but we have not observed it."
This is a possibility, if the collision signal is weak enough, it may indeed be ignored by the detector.
"Impossible," another plasma physics expert shook his head. "The waveform image of the electromagnetic wave is very obvious. In one third of the area, the energy of the helium 3 particles has already decayed beyond the threshold, and it need not be observed at all. It's off course ... you should be clear. "
The last word, this is an expert in plasma physics.
Without speaking, Lu Zhou nodded solemnly.
From the peak changes in the electromagnetic spectrum image, he has been able to make a judgment that the helium 3 atom as a bullet did not penetrate the plasma, but "missed" in the collision with the particles inside the plasma.
It may be confined in the electromagnetic field together with those plasmas, or it may break through the constraints of electromagnetic fields and plasmas, but the direction of motion has completely changed in continuous collisions ...
If the particles injected into the chaotic system cannot be observed, then it becomes a part of the chaotic system. Even if it still exists, it is still "missing" in the physical sense.
Research seems to be dead ...
"This idea may not work at all," took off the helmet, Professor Lazerson looked at the computer screen solemnly, and then looked at Lu Zhou. "The plasma used in the experiment only heated to 7000 degrees , The density is far from the density of the plasma in the stellar ... "
Professor Lazersson did not finish his speech, but the meaning was clear.
Even if the difficulty was reduced to this level, the helium 3 particles did not penetrate the entire plasma as expected. Not to mention that it is in a stellar orbit with temperatures reaching hundreds of millions.
After looking at the dark screen solemnly, and accompanying the laboratory researchers for a long silence, Lu Zhou said suddenly.
"We need a more powerful atomic gun!"
"Yes, we need a more powerful atomic gun. It is best to use the Swiss hadron collider as an acceleration module, plug our helium 3 to the moon rocket and let it hit the road. All the particles that came through broke through instead of knocking them out ... "Professor Lazelsson laughed with a mockery and shook his head." But you know, this is obviously impossible. "
"Not so exaggerated," Lu Zhou shook his head and continued. "I just calculated it. We just need to increase the acceleration electric field strength of the atomic gun to 1T. In theory, our He3 particles can penetrate the plasma. After that, hit the target material with a limited deflection angle. "
This has not been rigorously calculated, it is a conservative estimate based on experience.
1T may not be needed, but 1T is definitely enough.
"This is already exaggerated! The intensity of the constrained magnetic field of the star simulator is only 10T!" Tu Moxingzi flew across, Professor Lazerson finally could not help but growled, "Seriously, you mathematically calculate yourself Is there a concept for the data coming out? Do you know how expensive the superconducting materials and those used liquid helium are? "
After all, it is still a matter of funding.
Although PPPL is very powerful, it took a lot of money to build this laboratory, but the annual funding is actually only 40 million US dollars.
This money needs to be allocated to many projects, and the money that can be used for the "He3 Atom Probe" technology is probably less than $ 4 million.
They use the replaced old equipment to modify and recycle parts, not only to save time in customizing new equipment, but also to save money.
After all, every experiment they make is burning money.
Professor Lazelsson's mind ~ EbookFREE.me ~ even came up with a irritable thought.
Perhaps working with this guy was a wrong decision from the start.
The other engineers in the lab looked silent as Professor Lazelsson looked at his temper.
Lu Zhou's request is indeed too much, as if a rich man said to the poor, since bread is not enough to fill his stomach, why not eat cake?
No snoring, Lu Zhou waited quietly for him to finish everything.
He looked at Professor Lazelsson, whose beard was trembling with anger, before he coughed softly and said slowly.
"If, can I solve the funding problem?"-
(
Thanks to the leader of the "lost bookworm" for the reward!
Having said that these days have been erupting, can I just ask for a ticket? If I can, I'll ask ... for a monthly pass! !! !! )
