Scholar’s Advanced Technological System

The bubbles in the liquid can be stably suspended and periodically pulsed, driven by a certain sound field. On the other hand, when the phase is collapsed, bubbles can produce millions of volumetric compression ratios and high temperature high pressures over the order of picoseconds. When the drive sound pressure is high enough, the bubble emits light, which is called acoustic emission.

With appropriate driving conditions, acoustic luminescent bubbles can remain spherical, and non-linear vibrations can accurately repeat millions or hundreds of millions of cycles. It is precisely this characteristic that provides a possible way to achieve controllable fusion in relatively cold conditions.

At this moment, in the Jinling Institute of Higher Studies.

The centre of the acoustic laboratory of the Institute of Physics has been temporarily recruited by the controllable fusion miniaturization research team led by the Ark. A transparent container measuring approximately three inches in radius is placed on the laboratory table in the central area of the laboratory.

The entire transparent container is filled with clear and viscous concentrated sulfuric acid, high-power ultrasound generators are connected to both sides of the container, and a variety of precision instruments and equipment are displayed around the entire set of devices, ready to collect experimental data at all times.

Because the phenomenon of acoustic luminescence occurs in picosecond-level flashes, it is difficult for a typical laboratory camera to gather all the flash information, especially at the moment when the bubbles collapse to a minimum.

For this experiment, the Ark even borrowed the only "locked phase integral photographic imaging experiment system” from the Golden Loud Acoustics Institute.

In addition to some special acoustic experiments, the system is generally used to study anti-submersible sounds. If it weren't for the face of the ark, the director of the acoustic institute would never have agreed to lend the equipment.

Standing next to the experimental device, he had completed the experimental preparation of the grand constitution and turned his attention to the ark standing beside him.

The ark nodded and said.

“Let's get started. ”

“Yes.”

Taking a deep breath, Sheng Xianfu walked to the nearest computer and quickly tapped a few buttons.

As a short mosquito sound passes, the high-power ultrasound generator begins to release ultrasound waves carrying huge amounts of energy into the solution.

Confirm that the sound pressure in the working fluid has reached the standard of 5 atmospheres and the ship immediately continues to command the way.

“Inject xenon! ”

“Yes!”

With the injection of xenon, a bubble slowly rises from the bottom of the container and floats in the center of the container driven by a sound field.

Immediately thereafter, the power of the ultrasound transmitter begins to gradually amplify, and the sound pressure applied to the bubbles increases as well.

As soon as the sound pressure on the bubbles reaches 15 times the standard atmospheric pressure, the xenon bubbles floating in concentrated sulfuric acid are like a bright light, flashing instantly from purple to white!

Seeing this scene, the researchers surrounding the experimental device showed a glimmer of joy on their faces.

Although this is only a test of the experimental device, and there is still a long way to go to true success, this is undoubtedly a good start.

The air bubbles suspended in the working liquid flashed continuously by 10 groups of light, and photographs were collected in the luminescent state by means of a locked phase integral imaging experimental system. Several acoustic physics experts from the Institute of Advanced Studies immediately analyzed the photographs to determine the luminescence temperature and power by spectrum.

After receiving experimental data from Sheng Xianfu's hands, the Ark looked briefly at it.

The light-emitting power is around 130W, flashing for a moment, but it's also quite astonishing. As for the peak bubble surface temperature, the most prominent group reached a horrific figure of 1.5 million Kelvins, just like a star floating in solution!

Of course, this data is not necessarily accurate.

After all, bubble collapse is an instantaneous thing, and it's not easy to measure the temperature indirectly, let alone reduce the data error.

“The results of the first phase of the experiment were successful, get ready for the next phase,” put the experiment report on the table, the ark continued to tell Sheng Xianfu standing next to him, “add a neutron shield layer to the container and prepare to inject deuterium mixture gas! ”

Sheng Xianfu nodded seriously: "Yes! ”

The first phase of the experiment was only to test whether the device was designed to be reasonable, to provide sufficient sound pressure for the bubbles to reach temperatures of more than one million Kelvins in an instant.

Now it seems that their experiments have been successful.

When the xenon floating in the working liquid is compressed to a point that is not visible to the naked eye, the energy at one point releases more dazzling rays of light than the point on the star.

While millions of Kelvin-level temperatures are still far from ignition conditions for controllable fusion, conditions that contribute to controllable fusion are not limited to temperature alone.

Sound pressure acting on the bubbles not only brings millions of Kelvins to the bubbles, but also terrible density!

Density, too, is a condition for fusion reactions!

At the behest of the ship, the researchers in the laboratory placed a transparent container in a black box made of neutron shielding material and shut down the lock-phase integral imaging experimental system, followed by a repeat of the previous experimental steps.

However, the incoming gas was changed from xenon to deuterium mixture, and the ultrasound power was increased from the original magnitude to a new magnitude!

The experiment continues.

While the black box blocks people's eyes, it doesn't stand in the way of anything.

Something doesn't need to be seen intuitively, and intuitive data is more reliable than anything else.

The data collected were immediately analysed in detail by the researchers who removed the containers filled with concentrated sulfuric acid from the black box and were responsible for the identification of radiation damage and neutron amplification rates.

Standing next to the researchers, the ark quietly awaited the results of the experiment.

That's about half an hour passed by.

Finally, the result came out.

“The observations are out!” There was a strong blessing on his face, and the researcher quickly handed over the completed experimental report to the Ark, reporting excitedly on his face, "By detecting the irradiation damage on the surface of the neutron shielded material, there was sufficient evidence to allow the surface to bombard the surface of the material with 2.5MeV of neutrons during the experiment… the neutron amplification rate was estimated at 1.7%! ”

“Confirm that the fusion reaction occurs! ”

The moment I heard that, everyone in the lab had an exciting look on their face, and I could barely cheer.

Especially Sheng Xianfu, excitedly squeezed his fists.

This experimental idea works!

There was no more exciting news for him.

Of course, while the results of the experiment were very encouraging, the experiment itself was not optimistic in terms of data on neutron amplitude.

From previous experiments, they had at best observed signs of fusion reactions, which were still far from being used for stable, controllable fusion reactions.

Staring at the data in the experimental report, Professor Li Changxia concentrated: “The neutron amplification rate is still too low to achieve stable operation of controllable fusion... this level of sound waves may not be enough. ”

The ship nodded in agreement with the location, saying: "You are right, under the current conditions, it is difficult to achieve a stable controllable fusion response. And to do that, we have to replace the working liquid. ”

Professor Li Changxia: “What kind of work fluid do you intend to try? ”

The ark shook its head: "I don't know, but I do have a possible idea. ”

“Thoughts? ”

“Yes," the ark nodded, "why don't we try the liquid metal if the conventional liquid at room temperature can't meet the requirements? For example, liquid lithium, I think it is a worthwhile choice...”
