China on June 24 completed the main structure of the Jiangmen Underground Neutrino Observatory (JUNO) in the southern province of Guangdong.
On June 24, the installation of the main structure of the Sinonu Experimental Detector in Jiangmen, Guangdong, China was completed.
The main structure consists of a giant spherical stainless steel mesh that will support JUNO's core equipment – a spherical detector as tall as a 13-story building, covered with 20,000 light-detecting photovoltaic tubes and filled with 20,000 tons of liquids with a special formula.
The main structure consists of a large spherical stainless steel mesh shell that serves as the core device supporting the JUNO detector – a spherical detector up to 13 stories high, covered by 20,000 photomultiplier tubes and filled with 20,000 tons of specially formulated liquid.
The entire structure was built in the center of a water tank located under a large cave in Jiangmen City. Engineers will use a pedestal to install acrylic spheres in layers from top to bottom inside the steel mesh. At the same time, photovoltaic tubes and other parts will also be attached to the steel mesh. Once completed, the acrylic sphere will be filled with a gleaming liquid, while the water tank will cover the entire detector to protect it from the natural radiation of the surrounding rocks.
The entire structure is built in the middle of a pool of a large underground cave in Jiangmen City. Engineers mounted plexiglass balls from top to bottom in a stainless steel mesh using a lifting platform. At the same time, photomultiplier tubes and other components will also be connected to the stainless steel mesh. When complete, the plexiglass ball will be filled with liquid scintillators and filled with water to completely cover the entire detector to protect it from radiation from surrounding rocks.
Neutrinos, also known as "ghost seeds", are elementary particles with a mass so small that they were once thought to have no mass. It is the second most abundant particle in the universe after the photon.
Neutrinos, also known as "ghost particles," are elementary particles of very small mass that were once thought to be massless. It is the number of elementary particles in the universe second only to light particles (photons).
As neutrinos pass through the detector, a very small portion of them interact with the liquid, producing flickering light detected by photovoltaic tubes in the form of neutrino signals for further calculation and study. Besides neutrinos from nuclear reactors, JUNO can also study neutrinos from supernovae, the Sun, Earth and our atmosphere.

The JUNO Observatory is operated by the Institute of High Energy Physics of the Chinese Academy of Sciences. Its power supply comes from the Yangjiang and Taishan nuclear power plants, both of which are more than 50 km away.

The $305.3 million ghost particle detector is expected to be completed and put into use by 2023, making it the second-largest neutrino testing facility in China. It is designed to detect and measure the quality of neutrinos with unprecedented accuracy and resolution, helping scientists better understand their mass, how they can change their identity midway through oscillations, and solve many mysteries about this basic but highly elusive particle.
The $305.3 million Spectre Particle Experiment Detector is scheduled to be completed and operational in 2023 and will be the second largest neutrino experimental facility in China. It is designed to discover and measure neutrino masses that do not yet have precision and resolution, help scientists better understand how they transform between oscillations, and solve the mystery of many elusive elementary particles.

I have to admit, China is too good.
I have to admit that China is fantastic

Growing too fast.
It's moving too fast

Don't go, you don't come, you don't do it. Dare to invest in educational science, dare to bear losses, take decades to research ... Then it will reap the fruits.
If you don't go, you won't come, and if you don't do it, you If you dare to invest in science education, dare to suffer losses, dare to spend decades of research and exploration, you will have gains.

China's basic research has gone so far, just to see that the value of more than $300 million for a machine to find something that seems worthless in life is enough to understand countries with little money can not follow.
China's scientific research has made great strides, and it only needs to see that they spent more than $300 million to build a machine to find something that seems worthless in life, and those poor countries will never be able to follow.

Too much money... The inventions of the world will be verified by China!
It's so rich... Those world inventions will be witnessed by China!

The truth is that I don't like China, but I have to admit, they do a lot of things.
In fact, I don't like China, but I have to admit that they can do a lot of things.

There's always someone coming in anyway.
No matter what, there will be criticism.

Seeing that people have DUNE also does JUNO. It's good to think about it, but when you'll be able to do something first.
Seeing that others have it, I want to do it myself, although the idea is very beautiful, but before that, you can make something first.

China is both rich and good, and it's hard to compete with China!
China is rich and powerful, and it is really difficult to compete with China!

It is very welcome for China to build the Neutrino Observatory. Thanks to the scientific knowledge from the West & their meticulously documented design, today countries race to experiment with science... Congratulations to China on following in the footsteps of the factory from the EU & US for its research contributions...
Very supportive of China's construction of neutrino detectors. Now that countries are racing to conduct scientific experiments, we have the opportunity to learn about Western scientific knowledge and those rigorous designs, and congratulate China on its contribution to scientific research in close succession with the European Union and the United States.
